Problem Description
I have a very simple problem for you. Given two integers A and B,your job is to calculate the Sum of A + B.
?
Input
The first line of the input contains an integer T(1<=T<=20) which means the number of test cases. Then T lines follow,each line consists of two positive integers,A and B. Notice that the integers are very large,that means you should not process them by using 32-bit integer. You may assume the length of each integer will not exceed 1000.
?
Output
For each test case,you should output two lines. The first line is "Case #:",# means the number of the test case. The second line is the an equation "A + B = Sum",Sum means the result of A + B. Note there are some spaces int the equation. Output a blank line between two test cases.

Sample Output
??? 一看就是大数!!
? 代码:

#include<stdio.h> #include<string.h> char al[1010],bl[1010]; int a[1010],b[1010]; int main() { int i,j,n; scanf("%d",&n); getchar(); int k=1; while(n--) { scanf("%s",al);//存为字符串 scanf("%s",bl); int l1=strlen(al); int l2=strlen(bl); memset(a,sizeof(a));//初始化 memset(b,sizeof(b)); printf("Case %d:n",k++); for(j=0,i=l1-1;i>=0;i--)//转化为数字 { a[j]=al[i]-'0'; j++; } for(j=0,i=l2-1;i>=0;i--) { b[j]=bl[i]-'0'; j++; } for(i=0;i<1009;i++)//位位相加 { a[i]=a[i]+b[i]; if(a[i]>=10) { a[i]-=10; a[i+1]++;//如果大于十下一位加一 } } printf("%s + %s = ",al,bl); for(i=1009;i>=0;i--) { if(a[i]!=0)//去掉前导零 break; } if(i>=0) for(;i>=0;i--) { printf("%d",a[i]); } printf("n"); if(n!=0) printf("n"); } } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
