Question

In a main()demonstration function, declare a pointer to an array of 500 School objects
and include code to handle any memory allocation errors that occur. In a loop, declare 500
array objects at a time, continuing to rewrite the main()function if necessary until you
create enough School objects to cause a memory allocation exception. (Hint: You might
want to display a count periodically to assure yourself that the School objects are being
created.) When memory is exhausted, display an appropriate message and terminate the
application. Save the file as School.cpp.

Answer 1

#include <stdlib.h>
#include <iostream>
#include <stdio.h>
#include <cstdlib>
#include <string>
#include <new>
class School{
private:
int schoolNumber;
public:
School(int _schoolNumber = 0) { schoolNumber = _schoolNumber;}
};
using namespace std;
int main(){
long int n = 500000000;
try{
School *shools = new School[n];
}
catch(bad_alloc& ex) {
cerr<<ex.what()<<endl;
system&#40;"pause"&#41;;
exit(1);
}
catch(exception& ex) {
cerr<<ex.what()<<endl;
system&#40;"pause"&#41;;
exit(1);
}
return 0;
}
