Are flowcharts and pseudocodes the same with algorithms?
firstly u hv knw what is algorithm;
when u write a program for any problem then there is many step by wgich we get to solution.so there is the way to express called algorithm in which we have many catogries which inlude flowchart,pseudocodes,and any coding language.
so,1stly there is no diff between flowchart n algo. becoze flowchart is type of this.
in flowchart we simply make drawing hw is process ll go as like ll flow of water from source to sink.
in pseudocoding we use our tongue language to express all mainly step not each line.
so.this is overall answer.
hv any confusion further write me on my board.
thank u.

Define Process With a Block diagram explain various states a process resides in?
In computing, a process is an instance of a computer program, consisting of one or more threads, that is being sequentially executed[1] by a computer system that has the ability to run several computer programs concurrently. A computer program itself is just a passive collection of instructions, while a process is the actual execution of those instructions. Several processes may be associated with the same program; for example, opening up several instances of the same program often means more than one process is being executed. In the computing world, processes are formally defined by the operating system (OS) running them and so may differ in detail from one OS to another. A single computer processor executes one or more (multiple) instructions at a time (per clock cycle), one after the other (this is a simplification; for the full story, see superscalar CPU architecture). To allow users to run several programs at once (e.g., so that processor time is not wasted waiting for input from a resource), single-processor computer systems can perform time-sharing. Time-sharing allows processes to switch between being executed and waiting (to continue) to be executed. In most cases this is done very rapidly, providing the illusion that several processes are executing 'at once'. (This is known as concurrency or multiprogramming.) Using more than one physical processor on a computer, permits true simultaneous execution of more than one stream of instructions from different processes, but time-sharing is still typically used to allow more than one process to run at a time. (Concurrency is the term generally used to refer to several independent processes sharing a single processor; simultaneously is used to refer to several processes, each with their own processor.) Different processes may share the same set of instructions in memory (to save storage), but this is not known to any one process. Each execution of the same set of instructions is known as an instance- a completely separate instantiation of the program.

Did that help?
Example of non-numerical data?
All computer data is numeric (they are digital computers after all). However, non-numeric data would include character arrays (strings) and objects that model real-life or abstract concepts, such as shapes, animals and people.
Structures can be defined as a tool for handling a group of logically related data items. They are user-defined and provide a method for packing together data of different types.
Structure Student
'declaring a structure named Student
Dim StudentId As Integer
Dim StudentName As String
'declaring two fields of different data types in the structure
End Structure

What is the meaning of statement missing in function main in c language?
Every C program must have a function, named main(), which is where the program starts execution. If there is no function main(), the computer does not know where to start running the program. The function main() must also do something; if it is just empty, some smarter compilers will note that there is nothing for the program to do, and will give this sort of error message to indicate that you forgot to tell the program what to do.
What are loop detectors are use to do?
A smoke detector detects smoke, a fire detector detects fire. A loop detector, surely, detects a loop.
Many detectors are also based on a loop of wire. For example, loops within the tarmac detect the presence of a car (a mass of ferromagnetic material) and triggers or promotes a change if the lights from red to green. Other sensors use loops as aerials, for example in theft-prevention systems used in shops.
In the context with computer programming, one can envision a variety of methods to detect a loop which fails to terminate (and unintentionally endless loop, or one which doesn't terminate in a timely fashion). Critical loops can be monitored for a maximum number of iterations or a maximum duration.
