从2开始求一定数目素数

# include <stdio.h>

int judge(long int i)
{
	for (long int a = 2; a < i; ++a)
	{
		if (i % a == 0)
			return 0;
	}
	return 1;
}

int main(void)
{
	long int val, k = 2, count = 0;
	printf_s("请输入素数个数：");
	scanf_s("%ld", &val);
	while (count < val)
	{
		if (judge(k) == 1)
		{
			printf_s("%6ld", k);
			++count;
		}
		++k;
	}
}
