How to get rid of errors of compilation.

Question

#include <iostream>
using namespace std;

int main() {
int k;
int p;
double i1;
double i2;
int s;
int result;
int r;
cin >> r;
cin >> k;
cin >> p;
cin >> s;
switch (r);{
case 0:;
{i1 = (k * p) / 100;
i2 = k + i1;
result = s / i2;
cout << result;
break;}
case 1:;
{i1 = (k * p) / 100;
i2 = k - i1;
result = s / i2;
cout << result;
break; }
default;
{cout << "Warning! You should type 0 or 1";
break; }}
return 0;

Answer 1

your case statements should be just case : not case :;

Answer 2

I have deleted all the semicolons, where it was needed. But I still get compilation error.

Answer 3

oh, the switch statement has a ; in front of it, that shouldn't be there. it should be
switch(r)
{
case 0:
{code}
case 1:
{code}
default:
{code}
}

Answer 4

what about break?

Answer 5

what do you mean? it's part of the code section

Answer 6

you should write your code something like thing so that the user knows what to type ;)

#include <iostream>
using namespace std;

int main()
{
int k, p, s, r, result;
double i1, i2;

cout<<"enter k "<<endl;
cin >> k;
cout<<"enter p "<<endl;
cin >> p;
cout<<"enter s "<<endl;
cin >> s;
cout<<"enter a choice 0 or 1 and press enter"<<endl;
cin >> r;

switch (r)
{ case 0:
i1 = (k * p) / 100;
i2 = k + i1;
result = s / i2;
cout << result;
break;
case 1:
i1 = (k * p) / 100;
i2 = k - i1;
result = s / i2;
cout << result;
break;
default:
cout << "Warning! You should type 0 or 1";
break;
}
return 0;
}
