动态开辟二维数组

#include<stdio.h> #inlcude<stdlib.h> #include<string.h> void Reverse(char *str) { char *p = str; char tmp; while (*p != '\0') { p++; } //p找到字符串结尾 for (p--; str < p; str++, p--) { tmp = *str; *str = *p; *p = tmp; } //p和str互换 } int main() { char str[] = "abcde"; Reverse(str); printf("%s\n",str); return 0; }
