去掉continue和goto语句，结果同上

//q
//c
//h
//b
#include<stdio.h>
int main()
{
	char ch;
	while ((ch = getchar()) != '#')
	{

		{
			printf("step 1\n");
			if (ch == 'b')
				break;
			else if (ch != 'c')
			{
				if (ch != 'h')
					printf("step 2\n");
				printf("step 3\n");
			}
		}
	}
		printf("done\n");
	return 0;
}

编写一个程序，读取整数直到用户输入0。
输入结束以后，程序应报告用户输入的偶数（不包括0）个数、这些偶数的平均值、输入的奇数个数及其奇数的平均数。

#define _CRT_SECURE_NO_WARNINGS 10
#include<stdio.h>

int main()
{
	int i;
	int sum_odd = 0;
	int sum_even = 0;
	int odd = 0;//奇数
	int even = 0; //偶数

	printf("输入整数，以0为结尾\n");
	while (scanf("%d", &i)==1)
	{
		 if (i == 0)
			break;
		 if (i % 2 != 0)
			{
				odd++;
				sum_odd = sum_odd + i;
			}
		else
			{
				even++;
				sum_even = sum_even + i;
			}
	}
	printf("odd is %d,even is %d\n", odd,even);
	printf("偶数平均值%d(不包括0),奇数平均值%d\n", (sum_even /even), (sum_odd /odd));
	return 0;
