Multiple If statements example (C++)

Multiple If statements example

If allows selection among multiple sections of the code depending on the condition of if statement.

Following code demonstrates basic operations on 2 integer values using multiple if statements.

Code

#include "stdafx.h"

#include "iostream"

#include "conio.h"

using namespace std;

int main()

{

            double num1,num2;

            char operation;

            cout<<"ENTER FIRST NUMBER  > ";

            cin>>num1;

            cout<<"ENTER SECOND NUMBER > ";

            cin>>num2;

          

            cout<<"ENTER OPERATION"<<endl;

            cout<<"+ FOR ADDITION"<<endl;

            cout<<"- FOR ADDITION"<<endl;

            cout<<"* FOR ADDITION"<<endl;

            cout<<"/ FOR ADDITION"<<endl;

            cout<<"A FOR ADDITION"<<endl;

            cin>>operation;

     

            if(operation=='+')

                           cout<<num1<<" + "<<num2<<" = "<<num1+num2<<endl;

            if(operation=='-')

                           cout<<num1<<" - "<<num2<<" = "<<num1-num2<<endl;

            if(operation=='*')

                           cout<<num1<<" * "<<num2<<" = "<<num1*num2<<endl;

            if(operation=='/')

                           cout<<num1<<" / "<<num2<<" = "<<num1/num2<<endl;

            if(operation=='A')

                     {

                           cout<<num1<<" + "<<num2<<" = "<<num1+num2<<endl;

                           cout<<num1<<" - "<<num2<<" = "<<num1-num2<<endl;

                           cout<<num1<<" * "<<num2<<" = "<<num1*num2<<endl;

                           cout<<num1<<" / "<<num2<<" = "<<num1/num2<<endl;

                     }

          

            _getche();

            return 0;

}

Output

ENTER FIRST NUMBER  > 6

ENTER SECOND NUMBER > 5

ENTER OPERATION

+ FOR ADDITION

- FOR ADDITION

* FOR ADDITION

/ FOR ADDITION

A FOR ADDITION

A

6 + 5 = 11

6 - 5 = 1

6 * 5 = 30

6 / 5 = 1.2
