如何判断两个数的奇偶性?
编程思路:(1)使用一个计数器count来判断终止条件;
(2)用除以2后的余数来判断是不是偶数。
程序如下:
编译连接:
运行结果:
由于偶数相差为2,源码棋牌源码购买平台所以可以优化代码:
源代码:
#include<stdio.h>int main() /*浙江宁海陆继信*/
{
/* 浙江宁海陆继信程序优化 */
int sumEven = 0;
int i=0;
while(i <= ) /* 循环直到 */
{
sumEven=sumEven+i; //偶数求和;
i=i+2; //偶数相差为2,编程酒店app软件源码不必判断;
}
printf("sumEven: %d\n" , sumEven); //打印结果
return 0;
}
