A basic structure of a C program typically consists of: 1. **Preprocessor Directives:** These are lines of code that begin with a `#` symbol. They are instructions to the compiler to include certain files or libraries before compiling the program. 2. **Main Function:** Every C program must have a `main()` function. It serves as the entry point of the program where execution begins and ends. Inside the `main()` function, you write the instructions for the program to perform. 3. **Variable Declarations:** Before using any variables, you declare them. This involves specifying the data type and name of the variable. Variables hold data that can be manipulated within the program. 4. **Executable Statements:** These are the actual instructions or statements that perform the desired tasks. They can include assignments, calculations, conditionals (if-else), loops (for, while), function calls, etc. 5. **Return Statement (optional):** The `main()` function typically ends with a `return` statement, which returns an integer value to the operating system indicating the success or failure of the program. The absence of a `return` statement implicitly returns 0, indicating successful execution. Here's a simple example: ```c #include int main() { // Variable declaration int num1, num2, sum; // Executable statements printf("Enter two numbers: "); scanf("%d %d", &num1, &num2); sum = num1 + num2; printf("Sum: %d\n", sum); // Return statement return 0; } ``` This program prompts the user to enter two numbers, calculates their sum, and then prints the result. Finally, it returns 0 to indicate successful execution. read less

It typically consists of sections such as preprocessor directives, global variable declarations, function prototypes, the main function, and user-defined functions. A clear structure ensures logical flow, improves code modularity, and promotes code reusability.

A typical C program follows a structured format. It starts with preprocessor directives, including header files and macro definitions. Next comes the main function, where execution begins. Within main, variables are declared, and statements are written to define program logic. Functions may be declared before or after main, containing reusable code segments. Comments enhance code readability and document its purpose. Finally, the program returns an integer value to the operating system via the return statement at the end of main. This structured layout facilitates organization and maintenance of C programs.
