Execution lifetime of a C/C++ program

Hi,

To calculate the time a ‘C’ code takes to go from memory to the CPU and back again , in short the required to execute the program can be calculated by the following function.

You call in the ‘clock’ function from the lib.

#include<time.h>

intmain(void)

{

    clock_t tStart = clock();

    ** Write your code here**

    printf("Time taken: %.2fsn", (double)(clock() – tStart)/CLOCKS_PER_SEC);

    return0;

}

Just run the program and at the end , along with the result it will also display the time it took your code to complete the full cycle of execution.
