字符串逆序pta c语言

以下是两种实现字符串逆序的例子：
1. 使用C语言实现字符串逆序

#include <stdio.h>
#include <string.h>

int fun(struct stu *p, int n, char *sname) {
    int i;
    for (i = 0; i < n; i++) {
        if (strcmp(p[i].name, sname) == 0) 
            return p[i].score;
    }
    return -1;
}

void reverseString(char *p) {
    int len = strlen(p);
    for (int head = 0, tail = len - 1; head < len / 2; head++, tail--) {
        char tmp = p[head];
        p[head] = p[tail];
        p[tail] = tmp;
    }
}

2. 使用C语言实现字符串逆序的另一种方法

#include <stdio.h>
#include <string.h>

void reverseString(char *p) {
    int len = 0;
    for (int i = 0; p[i] != '\0'; i++) {
        len++;
    }
    for (int head = 0, tail = len - 1; head < len / 2; head++, tail--) {
        char tmp = p[head];
        p[head] = p[tail];
        p[tail] = tmp;
    }
}
