Hi,
i am new to cprogramming and i want to do this thing. all in all i have 2 problems
1)how do you add answers?
Code:
A+B=ans1
C+D=ans2
ans1+ans2=ans3//i cant do this part
2)Next problem is that i cant add switches is there something i am doing wrong?
i wanted to add cases.
Code:
#include <cstdlib>
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
int A,B,C;
double total;
int cash,product;
double change;
switch (product){
case 1:
printf("how many product A: \n");
cin>>A;
break;
case 2:
printf("how many product B: \n");
cin>>B;
break;
case 3:
printf("how many product C: \n");
cin>>C;
break;
}
total=(case 1*10)+(case 2*20)+(case 3*30);
\\ unit price of product A is 10, product B is 20, product C is 30
printf("total amout due is: %lf \n", total);
printf("enter amount paid by customer: \n");
cin>>cash;
do{
change=total-cash;\\still not working
printf("total change will be: \n", change);
}
while(total>=cash);
system("PAUSE");
return EXIT_SUCCESS;
}
