Why is my code not compiling?

Question

#include <iostream>
using namespace std;

float cels_fahr (float tc) {
float tf;

tf = 1.8 * tc + 32;
return tf;
}

int main() {
float cels;
float fahr;

cout << "Type temperature in Celsius:" << endl;
cin << cels;

fahr = cels_fahr (cels);
cout << "Temperature in fahrenheit: " << fahr << endl;

return 0;
}

Answer 1

ohh. i see your problem. right after cout<<"type temperature......", there's a cin statement like this
cin<<cels, it should be cin>>cels;

Answer 2

OMG! Such a stupid mistake! haha
Working now.
Thanks a lot! :D

Answer 3

I tried that and it still won't compile.

Answer 4

include a prototype before main, i.e
float cels_fahr(float);
