The Calculator in C++ is very easy but some peoples don't know How to apply green color in it.

#include <iostream>
using namespace std;
int main()
{
int a,b;
char ch;
cout<<"+ | - | * | / |"<<endl;
cin>>ch;

if(ch=='+')
{
cout<<"Type a number: "<<endl;
cin>>a;

cout<<"Type another number: "<<endl;
cin>>b;
cout<<a+b<<endl;
}

if(ch=='-')
{
cout<<"Type a number: "<<endl;
cin>>a;

cout<<"Type another number: "<<endl;
cin>>b;
cout<<a-b<<endl;
}

if(ch=='*')
{
cout<<"Type a number: "<<endl;
cin>>a;

cout<<"Type another number: "<<endl;
cin>>b;
cout<<a*b<<endl;
}

if(ch=='/')
{
cout<<"Type a number: "<<endl;
cin>>a;

cout<<"Type another number: "<<endl;
cin>>b;
cout<<a/b<<endl;
}
cin.get();
system("pause");
return 0;
}


This is code of the calculator.

#include <iostream>
#include <windows.h>

using namespace std;

HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE) ;
int main()
{
WORD color = FOREGROUND_GREEN;
SetConsoleTextAttribute(hout, color) ;
cout << "This is colored text!" ;

cin.get() ;
return 0;
} This is code of green color.


#include <iostream>
#include <windows.h>
using namespace std;
HANDLE hout=GetStdHandle(STD_OUTPUT_HANDLE);

int a,b;
char ch;

{

}

{

}

{
cout<<"Type a number: "<<endl;
cin>>a;

cout<<"Type another number: "<<endl;
cin>>b;
cout<<a/b<<endl;
}
cin.get();
system("pause");
return 0;
}This is Calculator + Green Color.
