Re:我的为什么Wa啊,大牛在哪里,帮帮忙罗In Reply To:我的为什么Wa啊,大牛在哪里,帮帮忙罗 Posted by:inforyou at 2007-05-11 18:56:37 #include<iostream> using namespace std; int main(int argc, char* argv[]) { int k,i,j,sum=0,n,b[8] = {128,64,32,16,8,4,2,1}; char a[9][32]; cin>>n; for(k=0;k<n;k++) cin>>a[k]; for(k=0;k<n;k++) for(i =0,j=8; i < j; i++) { sum += b[i%8]*(a[k][i]-'0'); if(i == j-1) { if(j == 32) {cout << sum << endl; sum=0; } else { cout << sum <<"." ; j +=8; sum=0; } } } return 0; } 我参考你的编写了上述代码,AC,你的错误有两点: 1.题目要求不是输入一行二进制值后便输出其IP ADRRESS,而是输入N行二进制后 ,集体输出相应的IP ADRRESS. 2.当j==32后, 要使sum=0;当然以你错误的输出方式是不存在这个毛病的.
