program execution time calculate in c

#include <stdio.h>
#include <time.h>

int main() {
    clock_t start, end;
    double cpu_time_used;

    // Record the start time
    start = clock();

    // Your program logic goes here

    // Record the end time
    end = clock();

    // Calculate the execution time
    cpu_time_used = ((double) (end - start)) / CLOCKS_PER_SEC;

    // Display the execution time
    printf("CPU Time Used: %f seconds\n", cpu_time_used);

    return 0;
