Question

Is this code right:

#include <iostream>;
using namespace std;
main sring()
{
int a;
int b;
int c;
cin>>a;
cin>>b;
cin>>c;
/*First enter the first number
then enter the second number
and finally enter the sign to indicate the operation*/
if (c==-);
cout<<a-b<<endl;
if (c==+)
cout<<a+b<<endl;
if (c==/)
cout<<a/b<<endl;
if (c==*)
cout<<a*b<<endl;
if (c==%)
cout<<a%b<<endl;
else
cout<<"somethings wrong""<<endl;
}

Answer 1

#include <iostream>
using namespace std;
int main()
{
int a, b;
char c;
cin>>a;
cin>>b;
cin>>c;
/*First enter the first number
then enter the second number
and finally enter the sign to indicate the operation*/
if (c=='-');
cout<<a-b<<endl;
if (c=='+')
cout<<a+b<<endl;
if (c=='/')
cout<<a/b<<endl;
if (c=='*')
cout<<a*b<<endl;
if (c=='%')
cout<<a%b<<endl;
else
cout<<"somethings wrong""<<endl;
return 0;
}

Answer 2

Nope, it has to be

int a;
int b;
char c;
