Question

用C语言编程求出1至100中能同时被2和3整除的数值之和

Answer 1

main()
{
int i,sum=0;
for(i=1;i<100;i++)
{
if(i%2==0&&i%3==0)
sum=sum+i;
}
printf("sum=%d",sum);
}

结果：816

Answer 2

main()
{
int i;
int sum = 0;
for (i=1;i<=100;i++)
{
if (i%2==0&&i%3==0) sum += i;
}
printf("The SUM is %d\n", sum);
return 0;
}

Answer 3

for(int i=1,n=0;i<101;i++)
{
if(!(i%3&&i%2))
{
n+=i;
}
}
return n

Answer 4

#define START 1
#define END 100
#include<stdio.h>
main()
{
int sum=0;
for(int i=START;i<=END;i++)
if(i%2==0&&i%3==0)
sum+=i;
printf("%d",sum);
}
