How do you write a program to check the mistakes in paragraph?
This is no mean feat; actually no spell-checker / grammar-checker does a perfect job. Something simple you could do is just to check whether each word is in a dictionary. The data structures you use will depend on the programming language chosen, but having your dictionary in an array would definitely be slow - you may want to use something like a hashtable or a binary tree instead. However, an array can work for a proof of concept. If you write your program this way, something like an "Ode to the Spelling Checker" should pass without errors - although it is full of errors. The "Ode to the Spelling Checker" uses words that are in the dictionary - but the wrong word in each case, for example "eye" instead if "I", and "tolled" instead of "told". I paste a copy of the Ode here, for your easy reference - you'll have to read it out loud to make sense out of it! Eye halve a spelling chequer It came with my pea sea It plainly marques four my revue Miss steaks eye kin knot sea. Eye strike a quay and type a word And weight four it two say Weather eye am wrong oar write It shows me strait a weigh. As soon as a mist ache is maid It nose bee fore two long And eye can put the error rite It's rare lea ever wrong. Eye have run this poem threw it I am shore your pleased two no It's letter perfect awl the weigh My chequer tolled me sew.
Where is the tallahatchie bridge?
The Tallahatchie Bridge mentioned in the song "Ode to Billie Joe" was in Money, MS (about 10 miles north of Greenwood, MS). This is the bridge that Bobbie Gentry was crossing in the 11/10/1967 LIFE Magazine article (P. 99). It collapsed on 06/19/1972, supposedly after it was set afire by vandals (according to Wikipedia). It was replaced by the current concrete bridge. Here's an article about the original bridge's collapse:"Money Bridge Collapses, Greenwood Commonwealth, 06/20/1972, P. 1 (with 2 pictures)MONEY - The TallahatchieRiverBridge here collapsed between 11:30 and midnight Monday and presumably joined Billy Joe MacAllister in the muddy waters of the Tallahatchie.Leflore County Deputy Sheriff Ricky Banks said he received a call from Sheriff Rufus Freeman about 12:15 a.m. today telling him the bridge had collapsed.Leflore County Second District Supervisor Ray Tribble had called Sheriff Freeman earlier when two boys who had been fishing discovered the bridge had collapsed. The two boys reportedly had gone upstream to fish and upon returning to Money found they couldn't get over the collapsed span in the Tallahatchie River.Tribble and his county road foreman Homer Hawkins then blocked the bridge off at the approaches on each side to prevent anyone from driving into the river.""[Caption under photos] - BRIDGE OUT AT MONEY - The middle section of the Tallahatchie river bridge at Money tilted towards its upstream side as it collapsed Monday night. The steel suspension bridge was built in 1927. Staff Photos by Steve Bailey. "The bridge used in the movie "Ode to Billy Joe" did not cross the Tallahatchie River. It was located at Rising Sun, MS (about 10 miles south of Greenwood on the Yazoo River (Old Roebuck Road and CR 512). About 2 miles north of Greenwood (South of the original bridge), the Tallahatchie River and the Yalobusha River join to form the Yazoo River. The movie bridge was demolished in 1987 and replaced with the current concrete bridge.Also note: The song never mentions that Billy Joe DIED. It just says that he jumped off the Tallahatchie Bridge. Jumping off the original bridge from the song, however, would impale the jumper, as the waters are filled with sharp rocks.The movie depicts Billy Joe's body being pulled from the water from the north side of the movie bridge (Yazoo River). The movie flaw here is that, if Billy Joe drowned, his body would have floated upstream (against the current).
What are the design principles in BASIC programming language?
4.1 Design TradeoffsConceptual design involves a series of tradeoff decisions among significant parameters - such as operating speeds, memory size, power, and I/O bandwidth - to obtain a compromise design which best meets the performance requirements. Both the uncertainty in these requirements and the important tradeoff factors should be ascertained. Those factors which can be used to evaluate the design tradeoffs (usually on a qualitative basis) include:ReliabilityExpandabilityProgrammabilityMaintainabilityCompatibilityAdaptabilityAvailabilityDevelopment Status and CostRecommended practices for achieving reliability are given in section 4.5. The remainder of these features are discussed below.Expandability measures the computer system's ability to conveniently accommodate increased requirements by higher speed or by physical expansion, without the cost of a major redesign (ref. 84). The original design of the computer should provide for this type of growth, especially with regard to the memory and I/O sections. The general procedure is to determine all the functions that foreseeably could be demanded of the computer system, such as by reviewing growth problems of past programs, and to establish a range of possible requirements for each of the functions, which may double the present requirement. If possible, the likelihood of these expanded requirements should also be estimated. Modularity is a desirable method for providing expandability and should be incorporated whenever feasible.Prorgrammability, or the ease of programming the computer, should be considered early in the design. Past experience has shown that a balance between programming simplicity and hardware complexity is essential to prevent the costs of programming from becoming overwhelming. For example, sufficient memory capacity should be provided to accommodate program changes necessitated by increased performance or mission requirements; memory architecture should be designed to facilitate programming; and hard-wired memories should be avoided if many program changes are anticipated, because of the time and cost involved in implementing the changes. Adequate addressing facilities without artificial boundaries and a simple subroutine linkage are recommended. Considerations of programmability should include the efficiency of the source language, of the object code, and of converting from the source language to the object code, and the ease of using the source language and obtaining a completely coded computer program. If the computer is to be programmed in flight, the use of a compiler should be considered. A standard programming language, such as JOVIAL, SPL, or CLASP, is desirable and should be utilized for future applications if available. The degree of software sophistication and the availability of support software should be considered during the design.Maintainability should not be neglected when designing the computer. Repair should be readily accomplished during ground operation, and if inflight maintenance is desired, this should be specified as a design requirement. Inflight repair or reconfiguration is closely associated with reliability and, as such, the extent of reconfiguration made possible will be dependent upon the reliability required. Malfunctions can often be detected by self-check programs; inflight repair can be effected by automatic switching, or by manual operation on manned missions. The tradeoff should consider the use of a degraded mode of operation. Generally, the recommended prelaunch maintenance procedure is to remove bad components or subsystems from the system and replace them with backup equipment. To facilitate manual maintenance, subassemblies should be pluggable, require a minimum of disassembly for access, and be replaceable without adjustment. The design should provide case of accessibility and should minimize the possibility of damage to other parts during maintenance. If replaced assemblies are to be discarded rather than repaired, maximum cost goals for a replaceable module should be established.Compatibility should be developed between the computer and its interfaces, software, power levels, and, where necessary, ground computers. Standard interfaces and power levels should be implemented. Interface compatibility reduces the need for data conversion with peripheral equipment and is highly recommended. Data compatibility between models of a computer family should be provided to simplify the design of peripheral equipment. This consideration is particularly important when computers of different performance and architecture are interconnected. Source and object code compatibility between the spaceborne and ground-based computers is advantageous to facilitate programming.Adaptability is defined as the ability of the system to meet a wide range of functional requirements without requiring physical modification. Adaptability is needed when requirements are not well defined or if it is anticipated that the computer will be applied to a variety of missions and/or a number of space vehicles. Although this is similar to the need for growth discussed under "expendability," in this case, potential requirements should be anticipated by providing reserves in memory capacity, computational speed, word length, and I/O capability. Moreover, the design should consider specific features which allow tailoring a basic machine to different situations, such as an adjustable word length through byte organized operations, alterable or unused operation codes, reserved fields within formats, and adjustable speed. Caution must be taken that the increase in computer capabilities is in accordance with other development considerations.Availability is the probability that the computer is operating satisfactorily at a given time. It is closely related to reliability and repair time and should be considered in establishing reliability requirements. Since it takes into account the time required for malfunction detection and reconfiguration or repair, availability is particularly important during time-critical mission phases.Development Status and Cost are complex management-related factors which can have significant effects on the design. They require the estimation of a number of items such as the extent of off-the-shelf hardware use, design risks in developing new equipment using advanced technologies, potential progress in the state of the art during the design and development of the computer, etc. In estimating cost, the manager should consider the total long-range expenditures as well as initial outlays, and also the cost of potential delays in developing advanced techniques, etc.In addition to the above qualitative factors, tradeoffs should be determined on the basis of specified quantitative factors, such as precision, speed, capacity, weight, volume, and power.
What is the difference between welding rectifier and welding transformer?
A rectifier is an arrangement of diodes (devices that only allow current to flow in one direction), half-wave or full-wave, that converts AC to pulsated DC. A capacitor (condenser) is used to smooth out the pulsated DC for a more true DC supply. A transformer is usually comprised of two coils of wire around an iron core that changes the ratio of input voltage/current to output voltage/current. It does this by induction (a magnetic field crossing through a coil of wire producing electricity). The Primary coil (the input) usually is a bit thicker and has less windings than the Secondary coil (the output).
