用递归实现字符数组的反转

比如 char a[10] = {''a', 'b', 'c'};

用递归实现后打印为 ‘c’, 'b', 'a'

代码实现：

 

#include<stdio.h>
#include<string.h>void reverse(int length, char a[]);int main(){char a[10] = {'a', 'b', 'c', 'd', 'e'};int length = strlen(a);reverse(length, a);
}
void reverse(int length, char a[]) {if (length == 0) {return;}int index =  length - 1;printf("%c\n", a[index]);reverse(index, a);
}

 

 

 

运行结果：

 

e
d
c
b
a
