Question

高分！！问一个C语言的编程问题~ 判断一个数n能否同时被3和5整除~谢谢大虾们~

Answer 1

#include <stdio.h>
void main()
{
int n;
printf("please input the data:\n");
scanf("%d",&n);
if(n%3==0&&n%5==0)
printf("the %d can be divided by 3 and 5",n);
else
printf("the %d cannot be divided by 3 and 5",n);
return 0;
}

Answer 2

if(n%3==0 && n%5==0)
这条语句就够了。
---------------------------------
比如说：
int n = 15;
if(n%3==0 && n%5==0)
printf("%d能同时被3和5整除\n",n);
else
printf("%d不能同时被3和5整除\n",n);

Answer 3

#include<stdio.h>
main()
{
int a;
printf("请输入待判断整数:\n");
scanf("%d",&a);
if(a%3==0&&a%5==0)
printf("%d能被3和5整除",a);
else
printf("%d不能被3和5整除",a);
}
