Thread: Error in calculator program

Hello.

I am new to C++ programming and im trying to write rhis little calculator program and im getting some errors.

If anyone could help me that would be greatly appreciated!

Here is te code:

Code:

#include <iostream>
using namespace std;

int main()
{
    int number1 = 0;
    int number2 = 0;
    float number3 = 0;
    int opcheck = 0;
    string operator1;
    
    cout << "Enter a whole number: ";
    cin >> number1;
    cout << "Enter another whole number: ";
    cin >> number2;
    do {
        cout << "what type of math would you like done?\nEnter the word in lower case plaese: ";
        cin >> operator1;
        
        if ( operator1 == "addition" ) { 
         number1 + number2 = number3;         //ERROR
         opcheck = 1; }
    else if ( operator1 == "subtraction" ) {
          number1 - number2 = number3;          //ERROR
          opcheck = 1; }
    else if ( operator1 == "division" ) {
          number1 / number2 = number3;          //ERROR
          opcheck = 1; }
    else if { operator1 == "multiplication" ) {           //ERROR
          number1 * number2 = number3;
          opcheck = 1; )
    else {
         cout << "Sorry, I didn't quite understand what you ment...\nRemember, 'add' is not an acceptible responce, but 'addition' is!" << endl;
        
        } 
    while ( opcheck == 0 );
    
    system("pause");
}          
//and for some reason im getting an error on this line but theres nothin on it.

Im getting errors on the lines with the "ERROR" commented in.

Thank you for the help!!!

What do you expect those lines to do? Hint: = is not symmetric; what's on the left side and what's on the right side matters.

You also need to count open-curly braces and close-curly braces (hint: you have eight open and five close).

......

i dont know, please help me im so new at this.

Thank you, i finally got it working

Thanks again

Use switch statement in these type of situations. It's better. int main() means that it is returning some value after it's execution. Either make it void main() as in here or return any integer at the end usually zero ie, return 0;. It will justify your use of int main().
