1002 A + B Problem II
Time Limit: 2000/1000 MS (Java/Others) Memory Limit: 65536/32768 K (Java/Others)Total Submission(s): 69615 Accepted Submission(s): 12678
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 Input
2
1 2
112233445566778899 998877665544332211
Sample Output
Case 1:
1 + 2 = 3
Case 2:
112233445566778899 + 998877665544332211 = 1111111111111111110

二维数组专题总结
二维数组所有考点总结
2010-10-21
所有用到的的数组是:a[3][3]={{23,46,11},{99,45,82},{72,90,21}};
一:遍历打印输出二维数组的元素
#include <stdio.h>
void main(){
int a[3][3]={{23,46,11},{99,45,82},{72,90,21}};
for(int i=0;i<3;i++){
for(int j=0;j<3;j++){
printf("%d ",a[i][j]);
}
printf("\n");
}
}
思路:【1:每一个下标号对应的元素值是唯一的;
2:因为是二维数组,必须要遍历行,列所以需要两个循环变量;
3:在每一次循环遍历列数后,就用换行语句,可以打印输出标准的行列格式】
