Dynamic Memory Allocation

 Dynamic Memory Allocation

Dynamic memory allocation allows you to allocate memory at runtime using functions like malloc, calloc, and realloc. This is useful when you need to work with variable-sized data structures or manage memory efficiently.

#include <stdio.h>

#include <stdlib.h>

int main() {

    int* numbers = (int*)malloc(5 * sizeof(int)); // Allocate memory for 5 integers

    if (numbers == NULL) {

        printf("Memory allocation failed.\n");

        return 1;

    }

    for (int i = 0; i < 5; i++) {

        numbers[i] = i + 1;

    }

    for (int i = 0; i < 5; i++) {

        printf("%d ", numbers[i]);

    }

    free(numbers); // Release the allocated memory

    return 0;

}
