A - A+B Problem

Calculate a+b
Input
Two integer a,b (0<=a,b<=10)
Output
Output a+b
Sample Input
1 2
Sample Output
3
submit：

#include<stdio.h>
int main() {
	int a,b,c;
	scanf("%d %d", &a, &b);
	c = a + b;
	printf("%d", c);
	return 0;
}

B - A+B for Input-Output Practice (I)

Your task is to Calculate a + b.
Too easy?! Of course! I specially designed the problem for acm beginners.
You must have found that some problems have the same titles with this one, yes, all these problems were designed for the same aim.
Input
The input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per line.
Output
For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.
Sample Input
1 5
10 20
Sample Output
6
30
submit：

#include<stdio.h>
int main() {
	int a, b, c;
	while (~scanf("%d %d", &a, &b)) {
		c = a + b;
		printf("%d\n", c);
	}
	return 0;
}

C - A+B for Input-Output Practice (II)

Your task is to Calculate a + b.
Input
Input contains an integer N in the first line, and then N lines follow. Each line consists of a pair of integers a and b, separated by a space, one pair of integers per line.
Output
For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.
Sample Input
2
1 5
10 20
Sample Output

30
submit：

#include<stdio.h>
int main() {
	int n;
	scanf("%d", &n);
	int a, b, c;
	while (n) {
		scanf("%d %d", &a, &b);
		c = a + b;
		printf("%d\n", c);
		n--;
	}
	return 0;
}

D - A+B for Input-Output Practice (III)

Your task is to Calculate a + b.
Input
Input contains multiple test cases. Each test case contains a pair of integers a and b, one pair of integers per line. A test case containing 0 0 terminates the input and this test case is not to be processed.
Output
For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.
Sample Input
1 5
10 20
0 0
Sample Output

30
submit:

#include<stdio.h>
int main() {
	int a, b, c;
	scanf("%d %d", &a, &b);
	while(a!=0||b!=0){
		c = a + b;
		printf("%d\n", c);
		scanf("%d %d", &a, &b);
	}
	return 0;
}
