C语言字符指针实现字符串反转函数

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

void reverseString(char* str) { int len = strlen(str); char* start = str; char* end = str + len - 1; while (start < end) { char temp = *start; *start = *end; *end = temp; start++; end--; } }

int main() { char str[101]; printf('请输入字符串：'); fgets(str, 101, stdin); reverseString(str); printf('反转后的字符串为：%s', str); return 0; }
