题目：打印闰年要求：打印1000年到2000年之间的闰年思路：满足闰年的条件、1.可以被4整除但不能被100整除2.可以被400整除满足这两个条件之一的都可以代码实现int main(){int count = 0;//解法一int year = 1000;for (year = 1000; year <= 2000; year++){if ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0)){printf("%d ", year);count++;}}printf("\n总共有%d年\n", count);return 0; }运行结果 ;int FormatInput(char opt) {while (1){if (opt == 'Y' || opt == 'N'){if(opt == 'Y'){return 1;break;}else{printf("\n\n\n\n\n\n");return 0;break;}}else{while(getchar() != 10);// delete meaningless stringsprintf ("\n=============================\n INVAL...
