Question

write a c program that does not output anything, whose execution time is 1 second (use nested loops). Then convert the program to Python, and run it using the Python interpreter. How long does the Python version take?

Answer 1

#in c program:

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

int main()

{
double time_check=0;
clock_t start=clock();
int i=0;
while(i<1){
i=i+1;
while(i<1)
i=i+1;
i=i+1;
}
clock_t finish=clock();
time_check += (double)(finish-start) / CLOCKS_PER_SEC;
printf("time is: %f seconds",time_check);
return 0;
}

#in python:

import timeit
i=0
start=timeit.timeit()
while(i<1):
i=i+1
while(i<1):
i=i+1
i=i+1
end=timeit.timeit()
print("the time is",end-start)
