No match for 'operator >>' (operand types are ' std::basic_istream<char> and <unresolved and overloaded function types>

Question

#include <iostream>
#include <string>
using namespace std;
int main()

{
// perimeter finder

unsigned long int a;//sides of triangle
unsigned long int b; //sides of triane
unsigned long int c; // sides of triangle
string f ; //triangle type

cout << " type of triangle " << endl;
cin >> f >> endl;

cout << " enter first side " << endl;
cin >> a >> endl;

cout << " enter second side " << endl;
cin >> b >> endl;

cout << " enter third side " << endl;
cin >> c >> endl;

switch (f){

case: f = "equilateral";
cout << a*3 << endl;
break;

default:
cout << a+b+c << endl;
break;

}

return(0);

}

Answer 1

Actually you cannot use endl in cin and You can only use switch on primitive such as int, char and enum.
