C语言字符串反转

#include "stdio.h"

#include "string.h"

int reverse(char* bufIn,char* bufOut)
{
char* in = bufIn;
char* out = bufOut;

char t;

int i = 0, j = strlen(in) - 1;

while (j>=0)
{
out[i] = in[j];
i++; j--;
}
out[i] = '\0';
return 1;

}

int main()
{
char str[] = "123456";//不能用char* str = " jdassafdjlas";
char rec[] = { 0 };

int vt = reverse(str, rec);

if (vt)
{
printf("rec = %s\n", rec);
}
system("pause");
