SUMMARY

The discussion focuses on implementing a C++ program to manage and display the number of children a person has using a class called PersonInfo. The key functions include SetNumKids(int), IncNumKids(), and GetNumKids() const. The correct implementation involves calling person1.IncNumKids() to increment the number of kids and then using person1.GetNumKids() to retrieve and display the updated count. The final output should reflect the incremented number of kids after the function call.

PREREQUISITES
  • C++ programming fundamentals
  • Understanding of classes and objects in C++
  • Basic knowledge of function definitions and calls
  • Familiarity with input/output operations in C++
NEXT STEPS
  • Explore C++ class constructors and destructors
  • Learn about operator overloading in C++
  • Investigate C++ access specifiers: public, private, and protected
  • Study C++ inheritance and polymorphism concepts
USEFUL FOR

C++ developers, computer science students, and anyone interested in object-oriented programming principles in C++. This discussion is particularly beneficial for those learning to manage state within classes.

Print person1's kids, apply the IncNumKids() function, and print again, outputting text as below. End each line with newline.
Sample output for below program:

Kids: 3
New baby, kids now: 4
Sample program:
Code:
#include <iostream>
using namespace std;

class PersonInfo {
   public:
      void   SetNumKids(int personsKids);
      void   IncNumKids();
      int    GetNumKids() const;
   private:
      int    numKids;
};

void PersonInfo::SetNumKids(int personsKids) {
   numKids = personsKids;
   return;
}

void PersonInfo::IncNumKids() {
   numKids = numKids + 1;
   return;
}

int PersonInfo::GetNumKids() const {
   return numKids;
}

int main() {
   PersonInfo person1;

   person1.SetNumKids(3);

   <STUDENT CODE>

   return 0;
}

Below, do not type an entire program. Only type the portion indicated by the above instructions (and if a sample program is shown above, only type the <STUDENT CODE> portion.)

ok so i got this part so far which is correct according to the homework:
Code:
cout << "Kids: " <<person1.GetNumKids()<< endl;
PersonInfo IncNumKids;
cout << "New baby, kids now: " << I DONT KNOW WHAT TO PUT HERE<<endl;
i can't figure out what will display the number afterwards. I am guessing it has to do with IncNumKids but i don't know what.

Hi Pippy! (Smile)Writing [m]person1.GetNumKids()[/m] is like asking person1 how many kids he has.
Then you can print that with [m]cout[/m] as you have. Good! (Nod)When he gets a baby, you need to tell him he has an extra kid by writing [m]person1.IncNumKids()[/m].
That is, that person1 should increment the number of kids he has. (Thinking)Afterwards, you can ask again how many kids he has with [m]person1.GetNumKids()[/m] and print that. (Wasntme)
 
Code:
cout << "Kids: " <<person1.GetNumKids()<< endl;
PersonInfo IncNumKids;
person1.IncNumKids();
cout << "New baby, kids now: " <<person1.GetNumKids() <<endl;

it worked :o
