preprocessor directives

Comment

/* These are preprocessor directives in C. They might sound like quite a mouthful, 
   but they're simply instructions that tell the compiler to include libraries.
   These libraries contain a set of pre-written functions and tools, making it easier 
   to perform various tasks without reinventing the wheel. */

#include <stdio.h>   // Library for standard input/output operations
#include <stdlib.h>  // Library for memory management and general utilities

// It is preprocessor directives that allow access to these sets of functions

int main(void) {
    printf("Hello, World!\n"); // printf is imported from stdio
    
    // Allocate memory for an array of 10 integers using malloc from stdlib
    int *var = malloc(10 * sizeof(int)); // malloc is imported from stdlib
    
    // Check if malloc was successful
    if (var == NULL) {
        printf("Memory allocation failed!\n");
        return 1;  // Exit the program if memory allocation fails
    }

    // Assign values to the allocated memory
    for(int i = 0; i < 10; i++) {
        var[i] = i;
    }

    // Print values stored in allocated memory
    for(int i = 0; i < 10; i++) {
        printf("%d ", var[i]);
    }
    printf("\n"); // Newline for cleaner output

    // Free the allocated memory to prevent memory leaks
    free(var);

    return 0; // Indicate successful program completion
}
