1001. A+B Format (20)

Calculate a + b and output the sum in standard format -- that is, the digits must be separated into groups of three by commas (unless there are less than four digits).

Input
Each input file contains one test case. Each case contains a pair of integers a and b where -1000000 <= a, b <= 1000000. The numbers are separated by a space.

Output
For each test case, you should output the sum of a and b in one line. The sum must be written in the standard format.

Sample Input
-1000000 9
Sample Output
-999,991

#include <stdio.h>
#include <math.h> 
int main(){
	int a,b,sum,c;
	sum = 0;
	
	scanf("%d %d",&a,&b);
	sum = a+b;
	
	if(sum < 1000 && sum > -1000)
		printf("%d",sum);
	else if(sum < 1000000 && sum > -1000000)
		printf("%d,%03d",sum/1000,abs(sum%1000));
	else{
		c = sum%1000000;
		printf("%d,%03d,%03d",sum/1000000,abs(c/1000000),abs(c%1000));
	}
			
	return 0;
}

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int a, b, sum, c;
    sum = 0;

    scanf("%d %d", &a,&b);
    sum = a + b;

    if(sum < 1000 && sum > -1000)
        printf("%d\n",sum);
    else if(sum < 1000000 && sum > -1000000)
        printf("%d, %03d\n", sum/1000, abs(sum % 1000));
    else {
        c = sum % 1000000;
        printf("%d, %03d, %03d\n", sum / 1000000, abs(c/1000000), abs(c%1000));
    }

    return 0;
}

abs头文件是stdlib.h，不是math.h吧 我是在Linux下测试的

同楼主，我是第十个测试点一直错

[季夏未央]

第十六行 printf("%d,%03d,%03d",sum/1000000,abs(c/1000000),abs(c%1000));可能有点问题

999999+9999999=1，999，998

[小小怪中式咖啡]

#include <iostream>
#include <cstdio>
#include <cstdlib>

using namespace std;

int main()
{
int a, b, sum, c;
sum = 0;

scanf("%d %d", &a,&b);
sum = a + b;

if(sum < 1000 && sum > -1000)
printf("%d\n",sum);
else if(sum < 1000000 && sum > -1000000)
printf("%d,%03d\n", sum/1000, abs(sum % 1000));
else {
c = sum % 1000000;
printf("%d,%03d,%03d\n", sum / 1000000, abs(c/1000), abs(c%1000));
}

return 0;
}
20分代码

[蕾姆的小迷弟]

a , b = input().split(' ') s = int(a) + int(b) if s < 0: s1=str(-s) print('-',end='') else: s1=str(s) for i in range(1,len(s1) + 1): print(s1[i-1] ,',' if i%3==len(s1)%3 and i!=len(s1) else '', sep='', end='') #9行搞定
