What are the six stages that typical c programs go through to be executed?

Answer 1

First of all the source code is get compiled and the object code is returned i.e.binary code(machine language).Then the Linker, a computer program that takes one or more objects generated by a compiler and combines them into a single executable program. Now when the program is executed then the .exe file is first loaded into the memory and then executed by the processor.

In short the steps are:

1.Compilation

2.Linking

3.Loading

4.execution

Answer 2

Every C++ program contains one or more functions, one of which must be named main . A function consists of a sequence of statements that perform the work of the function. The operating system executes a program by calling the function named main. That function executes its constituent statements and returns a value to the operating system. Here is a simple version of main does nothing but return a value: int main()

{

return 0;

}

The operating system uses the value returned by main to determine whether the program succeeded or failed. A return value of 0 indicates success. The main function is special in various ways, the most important of which are that the function must exist in every C++ program and it is the (only) function that the operating system explicitly calls. We define main the same way we define other functions. A function definition specifies four elements: the return type, the function name, a (possibly empty) parameter list enclosed in parentheses, and the function body. The main function may have only a restricted set of parameters. As defined here, the parameter list is empty;

The main function is required to have a return type of int, which is the type that represents integers. The int type is a built-in type, which means that the type is defined by the language. The final part of a function definition, the function body, is a block of statements starting with an open curly brace and ending with a close curly: {

return 0;

}

The only statement in our program is a return, which is a statement that terminates a function. When the return includes a value such as 0, that value is the return value of the function. The value returned must have the same type as the return type of the function or be a type that can be converted to that type. In the case of main the return type must be int, and the value 0 is an int. On most systems, the return value from main is a status indicator. A return value of 0 indicates the successful completion of main. Any other return value has a meaning that is defined by the operating system. Usually a nonzero return indicates that an error occurred. Each operating system has its own way of telling the user what main returned. == Having written the program, we need to compile it. How you compile a program depends on your operating system and compiler. For details on how your particular compiler works, you'll need to check the reference manual or ask a knowledgeable colleague. Many PC-based compilers are run from an integrated development environment (IDE) that bundles the compiler with associated build and analysis tools. These environments can be a great asset in developing complex programs but require a fair bit of time to learn how to use effectively. Most of these environments include a point-and-click interface that allows the programmer to write a program and use various menus to compile and execute the program. Learning how to use such environments is well beyond the scope of this book. Most compilers, including those that come with an IDE, provide a command-line interface. Unless you are already familiar with using your compiler's IDE, it can be easier to start by using the simpler, command-line interface. Using the command-line interface lets you avoid the overhead of learning the IDE before learning the language.

Answer 3

For TurboC:

First save the program you have written . then press Alt+f9 check weather there are any errors rectify them . This is called compiling the program . then press ctrl+f9. enter the input you desire to . this is called running the program

if you use getch() function the output comes at the time of running the program

or else you need to press Alt+f5. you will get the desired output

Answer 5

Write the C program (any editor will do); compile and link it; run the resultant executable.
