Below is the explanation of the above program. With a description explaining the program’s meaning and use.
1. What is meant by the structure of a program?
The structure of a program is defined by its control flow, as structures are built up of blocks of codes. These blocks have a single entry and exit in the control flow.
2. What is the structure of C program syntax?
Any C Program can be divided into header, main() function, variable declaration, body, and return type of the program.
3. Why C is a structured program?
C is a structured programming language because it divides the programs into small modules called functions which makes the execution easier.
Jan 16, 2023 · This section of a C program’s structure comprises the code’s primary purpose. The main () function is when the compiler begins running code. It may make use of user-defined functions as well as built-in and global variables. The main () function’s return type is not required to be an int and can alternatively be void.
There are three basic steps involved in compiling a C program: preprocessing, compilation of C source code to machine code (or assembly) (also called object code), and linking of multiple object files into a single binary executable program. Each of these steps are described below. The three basic steps when compiling C programs are ...
