Problem: Take Two Numbers, Add Them Together And Display The Results. Now To Build The Flowchart… We Probably Need One Like This… Let’s Add The Routines… Start Get Number 1 Get Number 2 Number 3 = Number 1 + Number 2 Display Number 3 Stop What Now??? Let’s Program Using It. Which Language Do You Want To Use? C++, Visual C++ Or Visual Basic? Let’s Start With C++

Let’s Put The Chart Up For A Reference. Now We Begin With A Comment Line. // Program Name: Test.cpp Then We Include A Reference To The iostream File. #include Now We Setup Our Main Routine. void main( ) { Then Define Our Integers. int test1; int test2; int test3; Get Input From User And Store It In Integers. cout << “Enter number 1:”; cin >> test1; cout << “\n”; cout << “Enter number 2:”; cin >> test2; We Add Them Together. test3 = test1 + test2; And Print The Results. cout << “The total is: \n”; cout << test3; cout << “\n”; } Compile And Run The Program.
