Introduction: In previous article i explained Else if ladder or multiple else if to check the day corresponding to number in C++ Language and Else if ladder or multiple else if to check the month corresponding to number in C++ Language. In this article i am going to explain how to perform addition(+), subtraction(-), multiplication(*), division(/) and modulus (%) operations on two numbers corresponding to selected operator from + , - , * , / ,% using ladder else if or we can say multiple else if statement in C++ Language.Modulus operator(%) gives the remainder after integer division e.g divide 10 by 4 and you will get 2 as remainder Let's understand by creating a program.
#include<conio.h>
#include<conio.h>
#include<iostream.h>
main()
{
int a,b,c;
cout<<"Enter first number : ";
cin>>a;
cout<<"Enter second number : ";
cin>>b;
cout<<"Enter any
operator from + , - , * , / ,% : ";
cin>>op;
if(op=='+')
{
c=a+b;
cout<<"Sum
of "<<a<<" and "<<b<<"
= "<<c;
}
else if(op=='-')
{
c=a-b;
cout<<"Subtraction
of "<<a<<" and "<<b<<" = "<<c;
}
else if(op=='*')
{
c=a*b;
cout<<"Multiplication
of "<<a<<" and "<<b<<" = "<<c;
}
else if(op=='/')
{
c=a/b;
cout<<a<<"
divided by "<<b<<"
= "<<c;
}
else if(op=='%')
{
c=a%b;
cout<<"Remainder
of "<<a<<" divided by "<<b<<" = "<<c;
}
else
{
cout<<"INVALID OPERATOR!! Please enter correct one";
}
getch();
}
Run
the program using Ctrl+F9
Output:
First Run
Enter first number :
4
Enter second number : 2
Enter any operator
from + , - , * , / ,% : *
Multiplication of 4 and 2 = 8
Second Run
Enter first number :
10
Enter second number : 40
Enter operator
from + , - , * , / ,% : +
Addition of 10 and 40 = 50
Third Run
Enter first number :
100
Enter second number : 20
Enter operator
from + , - , * , / ,% : -
Subtraction of 100
and 20 = 80
Fourth Run
Enter first number :
40
Enter second number : 5
Enter operator
from + , - , * , / ,% : /
40 divided by 5= 8
Fifth Run
Enter first number :
20
Enter second number :4
Enter operator
from + , - , * , / ,% : %
Remainder of 20 divided by 4 = 0
