Re:呵呵,还好,知道错了,高手能不能讲讲,getchar,和 scanf(%c) 的效果有什么不同?为什么改用 scanf(%c)就能过了In Reply To:呵呵,还好,知道错了,高手能不能讲讲,getchar,和 scanf(%c) 的效果有什么不同?为什么改用 scanf(%c)就能过了 Posted by:sunmoonstar_love at 2005-06-12 00:16:32 #include"iostream" #include"math.h" using namespace std; int main() { char str[32]; int i=0,j=0,n,sum,k; scanf("%d",&n); for( k=0;k<n;k++) { sum=0; scanf("%s",str); for(i=0;i<32;i++) { if(0<=i&&i<8&&str[i]!='0') sum+=pow(2,7-i); else if(8<=i&&i<16&&str[i]!='0') sum+=pow(2,15-i); else if(16<=i&&i<24&&str[i]!='0') sum+=pow(2,23-i); else if(24<=i&&i<32&&str[i]!='0') sum+=pow(2,31-i); j++; if(j%8==0) { printf("%d",sum); sum=0; if(i<24) printf("."); else printf("\n"); } } } return 0; } 这个程序是AC了的,但用gets(str)代scanf("%s",str);程序就会有问题。。。。 Followed by: Post your reply here: |
