Question

求1-100之间的偶数，使用while语句实现

Answer 1

java中
public class p39 {

public static void main(String[] args) {

int s=0;
int i=2;
while(i<=100) {
s=s+i;
i=i+2;
}
System.out.println("s="+s);
}
}

C语言中
#include<stdio.h>
main()
{ int i=2，s=0;

while(i<=100)
{

s=s+i;
i=i+2;
}
printf("%d\n",s);

}

Answer 2

#include<stdio.h>
main()
{ int i=0;
while(i<=100)
{
if(i!=0&&i%2==0){
printf("%d\n",i);
}
i++;
}

Answer 3

#include<stdio.h>
main()
{
int i=0;
while(i<=100)
{
i+=2;
printf("%d\n",i);
}
}
