include include int main clockt begin clock double x double

#include #include int main() clock_t begin = clock(); double x; double sum; for (x =-1e10; x

Solution

#include<stdio.h>

#include<conio.h>

#include<time.h>

int main()

pthread_t my_thread;

void *function_thread()

{

clock_t begin = clock();

double x, sum;

for (x= (-1e10*2) ; x<(1e10*2);x++)

{Sum = sum + 1e-10;}

clock_t end = clock();

double exec_time = (double)(end-begin)/CLOCKS_PER_SEC;

printf(“sum %f execution time : %f\ ”,sum,exec_time);

}

//loop to call the thread function 4 times .

for(int i=1;;i<=4;i++)

{

pthread_create(&my_thread[i],NULL,,&function_thread,);

}

}
