楼上的程序简化
//函数 reverse 把 字符串 c中的字符 倒置
void reverse(char *c,int k){
char tmp;
if(k>1){
reverse(c+1,k-2);
tmp=c[0];
c[0]=c[k-1];
c[k-1]=tmp;
}
}
int main()
{
char *c="abcdefg";
int k=strlen(c);
reverse(c,k);
puts(c);
getch();
}
#include <stdio.h>
void InversePrint(char *str)
{
if (*str)
InversePrint(str + 1);
printf("%c", *str);
}
void main(void)
{
InversePrint("djsfko");
}
给你
