C语言编程小练习-用指针逆序输出字符串

一、问题描述
使用指针逆序输出字符串内容
二、代码
#include <stdio.h>
#include<stdlib.h>
#include<string.h>
char *reback_sort(char *p) {
int length = strlen§;
char * current = NULL;
int k = 0;
current = (char *)malloc(sizeof(char)*length);
for (int i = length - 1; i >= 0; i–) {
current[k] = p[i];
k++;
}
current[length] = p[length];
return current;
}
int main() {
char str[] = “hello bit”;
char *pp = NULL;
pp = reback_sort(str);
printf("%s", pp);
system(“pause”);
}
三、运行结果
