程序题：输入数字，输出字符串。 如何逆序一个字符串！

#include <stdio.h>

#define MAX_SIZE 100

int main()

{

int i;

int num;

int len;

char temp;

char src[MAX_SIZE];

printf("Please input number:\n");

scanf("%d",&num);

i = 0;

while(num != 0)

{

src[i] = (num % 10) + '0';

num = num / 10;

i++;

}

src[i] = '\0';

len = strlen(src);

for(i = 0; i < len / 2; i++)

{

temp = src[i];

src[i] = src[len - i - 1];

src[len - i - 1] = temp;

}

printf("src = %s\n",src);

return 0;

}

/* len = strlen(src);

for(i = 0; i < len / 2; i++)

{

temp = src[i];

src[i] = src[len - i - 1];

src[len - i - 1] = temp;

} */
