for(int F=0;F<=1;F=F+1)

疑问  
为啥 F有那么多选择？
最后 的F+1又是啥意思？？？
就是这个结构不懂...............




自..


# include<iostream.h>

int main( )

{int cc1,cc2,cc3,cc4,cc5,cc6;

for(int A=0;A<=1;A=A+1)

 for(int B=0;B<=1;B=B+1)

     for(int C=0;C<=1;C=C+1)

         for(int D=0;D<=1;D=D+1)

             for (int E=0;E<=1;E=E+1)

                 for(int F=0;F<=1;F=F+1)

                 {cc1=A||B;

                 cc2=!(A&&D);

                 cc3=(A&&E)||(A&&F)||(E&&F);

                 cc4=(B&&C)||(!B&&!C);

                 cc5=(C&&!D)||(D&&!C);

                     cc6=D||(!D&&!E);

                     if (cc1+cc2+cc3+cc4+cc5+cc6==6)

                    

                     {

cout<< "A:"<<(A==0?"不是":"是")<<"罪犯" <<endl;

cout<< "B:"<<(B==0?"不是":"是")<<"罪犯" <<endl;

cout<< "C:"<<(C==0?"不是":"是")<<"罪犯" <<endl;

cout<< "D:"<<(D==0?"不是":"是")<<"罪犯" <<endl;

cout<< "E:"<<(E==0?"不是":"是")<<"罪犯" <<endl;

cout<< "F:"<<(F==0?"不是":"是")<<"罪犯" <<endl;



                     }



                 

                 

                 

                 

                 

                 

                 }

                 return 0;

}

A<=1是啥意思啊
？？、

课本上说   
for (int  A=0;A<=1;A++ )
表示   枚举A的两种可能    如果表示A有4种可能性咋表示呢 ？？
