C -> Strcpy vs Memcpy for copying a string

Advertisemen

Was wondering which was quicker - strcpy is nearly twice as fast as memcpy:

#include <stdio.h>

#include <string.h>

#include <time.h>

int main(void)

{

       time_t start;

       int strcpytime,memcpytime;

       int testnum = 100000000;

       int i;

       char *in,out[12];

       in = "STRING_test";

       //memcpy

       start = clock();

       for (i=0;i<testnum;i++)

              memcpy(out,in,strlen(in)+1);

       printf("memcpy time: %dms\n",clock()-start);

       //strcpy

       start = clock();

       for (i=0;i<testnum;i++)

              strcpy(out,in);

       printf("strcpy time: %dms\n",clock()-start);

       return 0;

}
