C++- typedef (creating data-type aliases)

Step: 1 Create a new C++ project

Step: 2 Edit the code

•#include <iostream>

•using namespace std;

•int main()

•{

• typedef int class_size;

• class_size Physics, Chemistry, Total;

• cout << "Enter the number of students.\n";

• cout << "Physics: ";

• cin >> Physics;

• cout << "Chemistry: ";

• cin >> Chemistry;

• Total = Physics + Chemistry;

• cout << "\nNumber of students:";

• cout << "\n No. of Students in Phyics: " << Physics;

• cout << "\n No. of Chemistry: " << Chemistry << "\n";

• cout << "\n Total No. of Students: " << Total << "\n\n";

• return 0;

•}

 

Step: 3 Runt time views

Entering 1st typedef alias (Physics)

Entering second alias "chemistry

Final tepedef alias "Total", calculated with two other aliases.
