『陸』 用C語言為學校食堂做一個點菜系統,當用戶選擇自己喜歡的菜,所消費的錢就能顯示出來。 菜譜封面如下：
#include <stdio.h>
void main()
{
int a[4],i,j,m;
char t;
printf(」********************************* \n1.紅燒肉5.0元2.炸雞翅3.0元\n3.炒芹菜2.0元4.五香蛋1.0元\n5.退出\n********************************\n\n」);
printf(「請輸入您點的菜\n」);
for(i=0;i<=3;i++)
{ scanf(「%d」,&a[i]);j=i;
if(i<=2)
{ printf(「是否繼續點菜\n回復Y OR N\n」);
scanf(「%c」,&t);
if(t==Y)
continue;
else if(t==N){j=i;break;}
else {printf(「error,自動結算\n」);j=i;break;}}
}
for(i=0,m=0;i<=j;i++)
m=m+a[i];
printf(「總金額%d\n」,m);
}
