C Programming
Questions related to the C Computer Programming Language. This ranges all the way from K&R to the most recent ANSI incarnations. C has become one of the most popular languages today, and has been used to write all sorts of things for nearly all of the modern operating systems and applications. It it a good compromise between speed, power, and complexity.

What is getche command in c language?

What is C program execution life cycle?
C Program Development lifecycle!
C Program Development Cycle
A C program typically passes through four steps of development.
The solid lines show inputs into each step of the development cycle. Compile and Linkage Editor operations are performed by the C for AIX product, which also lets you specify what optional outputs are produced. Optional outputs are shown in the diagram by the broken lines. Descriptions of the steps follow below:
Design and Code
Involves designing a program to meet a specified requirement, and creating the programming language text files that will comprise the program source.
Compile
After checking for syntactical correctness, converts the programming language source files into machine readable instructions, where C variables are associated with memory addresses, and C statements are turned into a series of machine language instructions. The compiler can produces various forms of output, depending on the compiler options selected.
Linkage Editor
Links compiler output with external modules requested by the compiled program. C programs can use routines from C libraries or any object or archive file from the IBM XL family of languages. C programs can also use modules produced by the current or previous compilations. As well as linking the external modules, the linkage editor resolves addresses within the object module.
Run and Test
This stage can be both the final step in program development, or it can be an intermediate point in the program design and implementation process. A program's design commonly is further refined as a result of information gathered during testing.
binary search system
Does Percentage belong to interval continuous data type?

Write abstract class in c plus plus?

};
The main function of most Web browsers is to interpret (and display) Hypertext Markup (HTM).
The database environment refers to the components inside a database. Some of these include hardware, software, data, as well as the procedures.
What is a c-code to implement heapsort?
Heapsort(A) {
BuildHeap(A)
for i <- length(A) downto 2 {
exchange A[1] <-> A[i]
heapsize <- heapsize -1
Heapify(A, 1)
}
BuildHeap(A) {
heapsize <- length(A)
for i <- floor( length/2 ) downto 1
Heapify(A, i)
}
Heapify(A, i) {
le <- left(i)
ri <- right(i)
if (le<=heapsize) and (A[le]>A[i])
largest <- le
else
largest <- i
if (ri<=heapsize) and (A[ri]>A[largest])
largest <- ri
if (largest != i) {
exchange A[i] <-> A[largest]
Heapify(A, largest)
}
}
What are the functions of language?
Language has a variety of functions. Some of these include apologizing, asking a question, as well as expressing one's personal wishes.
Explain the allocation of memory cells when a function is called?
When you call a function, the stack pointer is adjusted to cater for the function's arguments (if any), the caller's return address (mandatory), the function's local variables (if any) and the function's exception handlers (if any).
What programs and applications run inside a window that can be opened closed or re sized?
All programs and applications run in a window, including console applications. However, with non-console applications, the programmer can choose the style of window by turning certain features on or off, such as whether it has a border or not, whether it is sizeable or not, whether it can be moved or not, and so on. In some rare cases, the programmer might expose some of these style options to the user so they can choose their own style of window.
How do you write c program of moving average?
