Thank you for your response, here is my test result:
/d/Downloads/mingw $ cat sprintf.cc
#include <stdio.h>
#define MAX 500000
int main () {
int i;
for (i = 0; i < MAX; i++){
char x[100];
sprintf(x, "x%dx%dx", i, i<<2);
}
}
/d/Downloads/mingw $ cat stdsprintf.cc
#include <cstdio>
using std::sprintf;
#define MAX 500000
int main () {
int i;
for (i = 0; i < MAX; i++){
char x[100];
sprintf(x, "x%dx%dx", i, i<<2);
}
}
/d/Downloads/mingw $ for i in `ls -d --color=never */bin`;
