Question

Hi, in this program I am adding adding person objects into person * persPtr[50]; and then sorting it by the person's name or salary.

What I can't do is after I sort the first few names or salary and try to run it again the same names appear again.

I need help by clearing the names and salary to begin it again.

Quick overview: I need to clear the names and salary after I run the program the first time so that the second run can run with completely new names and salary.

(As you can see the names and salary appear twice when I run the program the second time)

Here is the coding of the main:

int main()
{
char choice;
person * persPtr[50];
int n = 0;
bool s = true;
while(true)
{

do {
   persPtr[n] = new person;
   persPtr[n]->setPerson();
   n++;
   cout <<"Enter a another person? [y/n]";
   cin >> choice;
}while(choice == 'y');

cout<< "Unsorted list:" << endl;
for(int i = 0; i < n; i++)
{
persPtr[i]->printName();
persPtr[i]->printSalary();
}
bsort(persPtr, n, s);
cout<< "Sorted list:" << endl;
for(int i = 0; i < n; i++)
{
persPtr[i]->printName();
persPtr[i]->printSalary();
}
}
return 0;  
}

Explanation / Answer

#include<iostream>

using namespace std;

int main()

{

while(true)

{

char choice;

person * persPtr[50];

int n = 0;

bool s = true;

do {

persPtr[n] = new person;

persPtr[n]->setPerson();

n++;

cout <<"Enter a another person? [y/n]";

cin >> choice;

}while(choice == 'y');

cout<< "Unsorted list:" << endl;

for(int i = 0; i < n; i++)

{

persPtr[i]->printName();

persPtr[i]->printSalary();

}

bsort(persPtr, n, s);

cout<< "Sorted list:" << endl;

for(int i = 0; i < n; i++)

{

persPtr[i]->printName();

persPtr[i]->printSalary();

}

}

return 0;

}
