[C++]My first program ( Calculator )

[TheUltimate]

I just begon C++ and this is my first program thx to guides of ragezone

#include <iostream.h> 
#include <windows.h> 
#include <stdio.h> 
#include <conio.h> 
#include <iomanip.h> 
#include <string.h> 
int main() 
{ 
int keuze; 
long num1; 
long num2; 
char count; 
long som; 
char yesno; 
menu: 
system("cls"); 
 
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_BLUE|FOREGROUND_GREEN); 
cout << "1. Calculator" << endl; 
cout << "2. Exit" << endl; 
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY|FOREGROUND_BLUE|FOREGROUND_GREEN); 
cout << "Make your choice: " << endl; 
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY|FOREGROUND_RED); 
cout << "--> "; 
cin >> keuze; 
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_BLUE|FOREGROUND_GREEN); 
system("cls"); 
if(keuze==1){ goto calculator; } 
if(keuze==2){ goto exit; } 
else { 
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY|FOREGROUND_RED);      
cout << "Wrong input!" << endl; 
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_BLUE|FOREGROUND_GREEN); 
cerr << "Press any key to continue"; 
getchar(); 
goto menu; } 
calculator: //########### REKENMACHINE!! 
system("cls"); 
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_BLUE|FOREGROUND_GREEN); 
    cout << "Number1: "; 
    cin >> num1; 
    cout << "Number2: "; 
    cin >> num2; 
    cout << "calculation (*, +, - of /):"; 
    cin >> count; 
system("cls"); 
if(count=='*'){ som = num1 * num2; } 
if(count=='-'){ som = num1 - num2; } 
if(count=='/'){ som = num1 / num2; }; 
if(count=='+'){ som = num1 + num2; } 
    cout << "outcome:" << endl; 
    cout << num1 << " " << count << " " << num2 << " = " << som << endl << endl; 
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY|FOREGROUND_GREEN); 
cout << "You want to make another calculation?" << endl << "[Y/N]: "; 
cin >> yesno; 
if(yesno=='y'){ goto calculator; } 
if(yesno=='n'){ goto menu; } 
else { goto confirm_calc; } 
confirm_calc: 
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY|FOREGROUND_RED); 
cout << endl << endl << endl << "Wrong input!" << endl; 
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY|FOREGROUND_GREEN); 
cout << "Do you want to make another calculation?" << endl << "[Y/N]: "; 
cin >> yesno; 
if(yesno=='y'){ goto calculator; } 
if(yesno=='n'){ goto menu; } 
else { goto confirm_calc; } //########### REKENMACHINE!! 
exit: 
return 0; 
}

Owh my god, someone copied DOS STYLE CALCULATOR, jail him!!
Chill man, it's not worth it anyway.

Good work on first project, but it has some bad aspects like when I can enter letters there, so bsically i can make something like this: 3 Z 4 = ?? :biggrin:

Or something like this:

3 ZWSAGHGDA 4 = BUG

Practise more, make application with GUI, good luck. :clap:

It's nice but I guess it'll be better if you actually add in different buttons such as, "EVAPORATE" for erasing the numbers, or "ELIMINATE" for closing the program.

That's just an IDEA.

Anyways, nice Calculator, works fine / pretty good.
