题解 | #反序输出#

本题需用low，high指针前后夹击字符串数组，在每一次循环的过程中将两字符进行交换即可

#include<stdio.h>
#include<cstring>

void reverse(char *s){
    int low = 0,high = strlen(s)-1;
    while(low <= high){
        char temp;
        temp = s[low];
        s[low] = s[high];
        s[high] = temp;
        low++;
        high--;
    }
}

int main(){
    char s[100];
    while(scanf("%s",&s) != EOF){
        reverse(s);
        puts(s);
    }
}
