C/C++ :: Converting Dollar Amount To String

I'm quite new to programming and working on an algorithm for the program so we would have to change that into a workable code for our final program.

This is the algorithm teacher gave us for reference (with the functional decomposition):

3.9.3 convertNetPay()
// convertNetPay(in netPay, out netPayString)
char * convertNetPay(float netPay);
void convertNetPay(float netPay, char * netPayString);

Algorithm:
convertNetPay(in netPay, out netPayString)

Declarations: numHuns, numTens, numOnes as integer
OnesTable as array[9] string = {"One", "Two","Three", ...."Nine"}
"One" --> 0
"Two" --> 1
"Three" --> 2
...

[Code] .....

So that goes my entire instruction on the assignment and I will start my code and be probably asking quite a bit of questions!

Here is my code so far:

Spoiler

#include <stdio.h>
#include <stdlib.h>
#include <cstring>
void convertNetPay(float netPay, char *netPayString) {
int numHuns, numTens, numOnes;
