输入3个字符串,要求将字母按由小到大的顺序输出 请问我的程序错在哪?
#include <iostream>
#include <cstring>
using namespace std;
int main()
{int i,j;
string temp;
string string[3];
cout < < "please input 3 strings: " < <endl;
for(i=0;i <3;i++)
cin> > string[3];
cout < <endl;
for(j=0;j <2;j++)
for(i=0;i <3-j;i++)
if(string[i]> string[i+1])
{temp=string[i];string[i]=string[i+1];string[i+1]=temp;}
cout < < "the sorted strings: " < <endl;
for(i=0;i <3;i++)
cout < <string[i] < < " ";
cout < <endl;
system( "pause ");
return 0;
}

for(i=0;i <3;i++)

for(j=1;j <3;j++) //for(j=0;j <2;j++)原改为 for(j=1;j <3;j++) ，原来的会益出
for(i=0;i <3-j;i++)
