When attempting to randomly generate a string for a name attribute in a class, the output seems to print the same string for each object.
When I run this in the debugger, a unique name identifier IS generated for each Array object, however, when compiling and running the program, the name attribute is the same for both objects. Any help on why this may be happening would be much appreciated. Thanks!
Main:
int main() {
Array One(3);
Array Two(5);
cout << One.getName() << endl;
cout << Two.getName() << endl;
return(0);
}
Header file:
public:
Array(int arraySize= 10); // default constructor
Array(const Array &init); // copy constructor
~Array(); // destructor
void setName(); // set objects w/ unique names
int getCapacity() const; // return capacity
int getNumElts() const; // return numElts
string getName() const; // return name
void incrementNumElts(); // increment numElts
void incrementCapacity(); // increment capacity
private:
int capacity, // capacity of the array
numElts; // Elements in the array in use
int *ptr; // pointer to first element of array
static int arrayCount; // # of Arrays instantiated
string name;
};
Default Constructor in .cpp file:
Array::Array(int arraySize) {
setCapacity(( arraySize > 0 ? arraySize : 10 ));
setNumElts();
setName(); /* Giving each object a unique identifier.
Note: names will be different from the variable names in the
code. This will just make the prints a bit more clear about
which objects are being appended, copied etc.. */
ptr = new int[getCapacity()]; // create space for array
assert( ptr != 0 ); // terminate if memory not allocated
++arrayCount; // count one more object
}
The set function:
void Array::setName() {
srand(time(NULL));
string Str;
static const char alphanum[] =
"0123456789"
"ABCDEFGHIJKLMNOPQRSTUVWXYZ"
"abcdefghijklmnopqrstuvwxyz";
for(int i = 0; i < 4; ++i) {
Str += alphanum[rand() % sizeof(alphanum)-1];
}
name = Str;
}
The get function:
// Get unique identifier of array object
string Array::getName() const {
return name;
}
