int i=0;
while(i<=100)
{
printf("hello world....\n");
i++;
}
For the above program, how can I find the total time of execution of while loop.

5The body of the loop is not executed. – BLUEPIXY Jun 16 '17 at 05:42

1For loop execution `while( i <= 100 )`. It's already been answered here: https://stackoverflow.com/questions/5248915/execution-time-of-c-program – Azeem Jun 16 '17 at 05:42

1Could have searched before asking the question. This has already been answered. – Zeokav Jun 16 '17 at 05:43

2That will be executed really, really fast :-) You probably want to change `while(i>=100)` into `while(i <= 100)` – Support Ukraine Jun 16 '17 at 05:53

In header file time.h have that function. you can use that. You can see there is a clock_t variable called start which calls a clock() function. try this:
clock_t start = clock();
for ( i = 0; i < 100; i++ )
rand();
printf ( "%f\n", ( (double)clock() - start ) / CLOCKS_PER_SEC );
it will give you execution time. for this check your conditioj in while loop. it should "< 100" i think. check this code it will work for you.

loop will not execute `i=0` and in while loop it says `i>=100` – Vishwajeet Vishu Jun 16 '17 at 06:21
