C Program To Calculate Execution Time of a Program

Learn How To Find Execution Time of a Program in C Programming Language. This C Program makes use of the time.h header file which has definitions for clock() method.

In order to calculate the time taken by a C program to complete its execution, the library function clock_t clock(void) returns the clock ticks elapsed since the program started its execution.  The clock() can be invoked at the beginning of the C program with start value and a finish value can be invoked at the end of the C program. The final running time can be calculated by subtracting the start and finish values.

    OMG! This is fantastic. Now, I don’t need to go to an online compiler to measure the running time of my C program. Thanks a lot CodingAlpha.
