C_Variables.c

Here’s the updated C code with added documentation and an explanation:

#include <stdio.h>

/**
 * @brief The main function demonstrates basic variable usage and printing in C.
 * 
 * This function initializes an integer variable, assigns it a value, and prints that value.
 * 
 * @return int Returns 0 to indicate successful execution.
 */
int main() {
    int myVar = 5;  /**< Integer variable initialized with the value 5. */

    // Print the value of the integer variable
    printf("Variable value: %d\n", myVar);

    return 0;   /**< Return 0 to indicate successful execution. */
}

Explanation

1. Variable Initialization:

   • int myVar = 5; declares an integer variable myVar and initializes it with the value 5.

2. Printing the Variable:

   • printf("Variable value: %d\n", myVar); prints the value of the integer variable myVar. The %d format specifier is used for printing integer values in C.

3. Return Statement:

   • return 0; indicates that the program has executed successfully. The value 0 is returned to the operating system.
