Hi folks welcome to iTech Apps Lab Blog

This C++ program Demonstrates the use of Switch Statement

Scenario: Calculating salary increment and Tax amount for different Initial Scales

int net_Salary=0;

//showing menu on console
cout<<"************* SALARY CALCULATOR ***************"<<endl;
cout<<"\nSelect a pay scale from the menue : "<<endl;
cout<<"\n************* ***************** ***************"<<endl;
cout<<"\n************* Enter 1 for SPS6  ***************"<<endl;
cout<<"\n************* Enter 2 for SPS7  ***************"<<endl;
cout<<"\n************* Enter 3 for SPS8  ***************"<<endl;
cout<<"\n************* Enter 4 for SPS9  ***************"<<endl;
