How do I time my C program in Clion? Is there an option I can use to to tell me how long long my program took to run?

You can measure the time of your code from inside your C program.

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

int main() {
    clock_t start = clock();

    int n = 100; 
    int i=0;

    clock_t stop = clock();
    double elapsed = (double) (stop - start) / CLOCKS_PER_SEC;
    printf("\nTime elapsed: %.5f\n", elapsed);
    return 0;
