Program 1 - Create a class called TEST.
Write the following 4 functions for it.
Function 1
void testNullPtr().
In it, Declare a pointer int * ptrInt.
Assign NULL to the pointer.
What happen when you dereference a NULL pointer ?
( *ptrInt = 42; )
Function 2
void memoryLeak().
In it, Declare a pointer double * ptrDouble
Assign a new double to ptrDouble.
DeReference it and assign 3.123456789 as the value
Function 3
Declare the function header: string * deletePointer()
In it, Declare a pointer string * ptrString
Assign a new string to ptrString.
DeReference it and assign "Carlos" as the value.
write a return statement - for the pointer ptrString
Function 4
void testTwoAlias()
In it, Declare a pointer int * ptrAlias1
Assign new int to ptrAlias1
De-reference it and assign a value of 42
Also, Declare a 2nd pointer int * ptrAlias2 in the function.
copy the ADDRESS in ptrAlias1 to ptrAlias2
cout the address values stored in ptrAlias1 and ptrAlias2
cout the dereferenced values of ptrAlias1 and ptrAlias2
Explain the results
In the MAIN() function
Declare and instance of the Test class. TC1.
Test 1 - call the testNullPtr function, what happens.. explain it clearly.
Test 2 - Write a loop that runs a billion times. In the loop call memoryLeak() function.
Explain your results.
Test 3 - In the main function, declare a string *ptrS
Call the deletePointer function, assign deletePointer return value to ptrS.
Dereference ptrS. What do you get ?
Explain your results.
Test 4 - Call the testTwoAlias function.
