某市发生一起银行抢劫案，有甲乙丙丁四个嫌疑人，其中有一人是凶手，根据陈述判断谁是抢劫犯，求编程

# include
using namespace std;
int judgement()
{
for (int i=0;i<4;i++){
if(!(1==(1< continue;
if(!(2==(1< continue;
if(!(1==(8< continue;
return i; //i是抢劫犯
}
return -1;
}
void main()
{
int criminal=judgement();
switch(criminal)
{
case 0:
cout<<"the criminal is 丁"< break;
case 1:
cout<<"the criminal is 丙"< break;
case 2:
cout<<"the criminal is 乙"< break;
case 3:
cout<<"the criminal is 甲"< break;
default:cout<<"indefinite"< }
}

一个人是凶手 估计是一个人说的假话

丙啊
