在键盘上输入n个数，求其和。用for循环

main()
{
int i,n,a,sum=0;
printf("please enter the number of N:");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
scanf("%d",&a);
sum=sum+a;
}
printf("sum=%d",sum);
}

请问用的是什么语言？c的版本一楼有了，我给个java版本：

import java.util.Scanner;

public class sumUsingFor{
public static void main (String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Please key in the number of operants:");
int count = sc.nextInt();
System.out.println("Please start keying in the operants");
int sum = 0;
for (int i = 0; i < count; i ++){
sum += sc.nextInt();
}
System.out.println("The sum of the operants is: " + sum);
}
}
