Write a Program to Make a Simple Calculator in C++ Programming Language | Solved Programming Exercises

In this tutorial we will write a program in C++ Language to build a simple calculator. We will take two numbers from user and an operator. if operator is ‘+’ then add both numbers and so on.

We will use Dev C++ Compiler as an IDE.

How to install Dev C++ Compiler? Watch the Following Video.

So let’s Code in C++ Programming Language.

First of All, Create a C++ File then Include following Header Files:

#include"iostream"
using namespace std;

Above Header File is Used for Input and Output Purposes.

Second Step, take input from user.

main()
{
	int a,b;
	char op;
	cout<<"Enter First Number = ";
	cin>>a;
	cout<<"Enter Operator(+,-,*,/) = ";
	cin>>op;
	cout<<"Enter Second Number = ";
	cin>>b;
}

Next Step apply if condition to checker whether an operator is +,-,*/.

if(op == '+')
	{
		cout<<"Sum  = "<<a+b;
	}
	else if(op == '-')
	{
		cout<<"Minus = "<<a-b;
	}
	else if(op == '*')
	{
		cout<<"Mul = "<<a*b;
	}
	else if(op == '/')
	{
		if(b == 0)
		{
			cout<<"Cannot divide by zero";
		}
		else
		{
			cout<<"Div"<<a/b;
		}
	}
	else
	{
		cout<<"Invalid Operator";
	}

Finally Complete Code is Here:

//write a program to build
 a simple calculator in C++
#include"iostream"
using namespace std;
main()
{
	int a,b;
	char op;
	cout<<"Enter First Number = ";
	cin>>a;
	cout<<"Enter Operator(+,-,*,/) = ";
	cin>>op;
	cout<<"Enter Second Number = ";
	cin>>b;
	if(op == '+')
	{
		cout<<"Sum  = "<<a+b;
	}
	else if(op == '-')
	{
		cout<<"Minus = "<<a-b;
	}
	else if(op == '*')
	{
		cout<<"Mul = "<<a*b;
	}
	else if(op == '/')
	{
		if(b == 0)
		{
			cout<<"Cannot divide by zero";
		}
		else
		{
			cout<<"Div"<<a/b;
		}
	}
	else
	{
		cout<<"Invalid Operator";
	}
	
	
}
