C语言--指针实现字符串逆序输出

#include<iostream>#include<cstdio>#include<cstring>using namespace std;void invstr(char *a){int b= strlen(a);for(int i = 0;i<=b/2;i++){char temp;temp = a[i];//实现函数前一半和后一半交换a[i] = a[b-i-1];a[b-i-1] = temp;}}int main(){char c[10005]; //执行函数char *a = c;gets(c);invstr(c);printf("%s",c);//输出交换后的结果return 0;}
