Your code is some way short of a working solution.
I don't think you need a for loop in the main function, probably
a loop is needed in the data entry function. It is not clear whether
there is a set number of names to be entered or if the array is to be created dynamically as suggested in a previous post. If so then a while loop may be needed here eg
while (More)
{
cout << "Enter next name: ";
cin >> InString;
