C实现测试距今年的闰年数目

#include 

int main(int argc, const char* argv[])
{
	int i     = 0;
    int year  = 0;
    int count = 0;
	for(year = 1; year <= 2020; year ++)
	{
		if(((!(year % 4)) && (year % 100)) || (!(year % 400)))
		{
			printf("%6d", year);
			if(!( ++ i % 10 ))
				putchar(10);
            count++;
		}

	}
	putchar(10);

    printf("count=%d\n", count);
    
    return 0;
}

测试结果
