    Im trying to compile a program for a book
    heres my code
    #include <cstdio>
    #include <cstdlib>
    #include <iostream>
    using namespace std;
    int main(int nNumberofArgs, char* pszArgz[])
    int celsius;
    cout <<"Enter The Temperture in Celcius:";
    cin >> celsius;
    int factor;
    factor - 212 - 32; 
    int fahrenhiet; 
    fahrenhiet - factor * celsius/100 + 32;
    cout <<"Fahrenhiet value is:";
    cout << fahrenhiet << endl;
    return 0;
    It complies and opens fine but it dosen't work it seems that the math is wrong. If i type in 0 Celcius i get 4198592

    what are the errors?

    this should be one: factor - 212 - 32
    also initialize yourvars to 0, or something else. Factor should probably be a fraction, I forget what it is; 4/9 or something like that, and it should be stored in a double or a float; same with fahrenhiet.

    this should be another error: fahrenhiet - factor * celsius/100 + 32;
    I believe you want :fahrenhiet = factor * celsius/100 + 32;

    some entropy with that sink?

    You never initialize or assign to your variables.
    Both lines:
    factor - 212 - 32;
    fahrenhiet - factor * celsius/100 + 32;
    Do nothing. Perhaps those first '-'s ought to be '='.

    It will also be wrong because you are using integer arithmetic and not floating point arithmetic.
