请教一个 do..while 循环问题
所有的C语言程序可以使用do..while进行连续循环吗?# include <stdio.h>
int main(void)
{
float a,b,c;
float density,cubage,weight;
char ch
do
{
printf("请输入长方体的长a=");
scanf("%f",&a);
printf("请输入长方体的宽b=");
scanf("%f",&b);
printf("请输入长方体的高c=");
scanf("%f",&c);
printf("请输入长方体的重量weight");
scanf("%f",&weight);
cubage=a*b*c;
density=weight/cubage;
printf("长方体的体积为:%f\n",cubage);
printf("长方体的密度为: %f\n",density);
printf("您想继续么(Y/N): ");
scanf(" %c", &ch);
}while ('y'==ch || 'Y'==ch);
}
这个程序哪里有错误啊?不吝请教!
