Just a quick question

[Serge1005]

I created this code according to what the question asked me to do. But I am confused on the last part of the question. Problem: Modify the selection function presented in this chapter into an array of strings instead of an array of ints. Test the function with a driver program. The last part is where im lost. What is a driver program?

A "driver" program is simply a test program that calls your function with one or more test cases to exercise your function. A driver program will typically check the result returned by your function for each test case to check that the result is correct.

so do you think this code will be fine then??

#include <iostream>
#include <string>
using namespace std;
void selectionSort(string *array, int length);

int main() {
const int NUM_NAMES = 20;
string names[NUM_NAMES] = {"Collins, Bill", "Smith, Bart", "Allen, Jim",
"Griffin, Jim", "Stamey, Marty", "Rose, Geri",
"Taylor, Terri", "Johnson, Jill",
"Allison, Jeff", "Looney, Joe", "Wolfe, Bill",
"James, Jean", "Weaver, Jim", "Pore, Bob",
"Rutherford, Greg", "Javens, Renee",
"Harrison, Rose", "Setzer, Cathy",
"Pike, Gordon", "Holland, Beth" };
selectionSort(names,NUM_NAMES);
for(int i=0;i<NUM_NAMES;i++) {
cout<<names[i]<<"\n";
}
cout<<endl;
return 0;
}
void selectionSort(string *array, int length){
string temp;
int i,max;
while (length > 0)
{
max = 0;
for (i = 1; i < length; i++)
if (array[i] > array[max])
max = i;

temp = array[length-1];
array[length-1] = array[max];
array[max] = temp;
length--;
}
}
