Answer 1

Explanation:

The execution time of a function, a particular code segment, or a process is calculated using the clock() function. This function is available time.h. The following example may help you to understand the fact clearly.

#include <stdio.h>

#include <time.h>

#include <math.h>

int main()

{

double a, b, c;

printf("Enter the loating point base value \n");

scanf("%lf",&a);

printf("Enter the loating point power value \n");

scanf("%lf",&b);

printf("%lf, %lf",a,b);

// Calculate the time taken by fun()

clock_t t;

t = clock();

c=pow(a,b);

printf(" Value = %lf",c);

t = clock() - t;

double time_taken = ((double)t)/CLOCKS_PER_SEC;

printf("pow() took %.8lf seconds to execute \n", time_taken);

return 0;

}
