What is a C program’s structure?
a) Preprocessor directives, functions, and variables
b) Only functions and variables
c) Only main function
d) None of the above
Answer:
a) Preprocessor directives, functions, and variables
Explanation:
A typical C program consists of several components: preprocessor directives (such as #include), global variables, functions, and the main() function. The preprocessor directives are processed before the compilation begins, and they often include files or define constants. The main() function is the entry point of the program, where execution starts.
The structure of a C program is important because it dictates how the code is organized and executed. Properly structuring your program ensures that it is readable, maintainable, and efficient.
