How do you go about randomly assigning alternating vowels and consonants? I have created arrays for each but can not determine the way to alternate them.

...how do i loop it so that i can generate the number of names that the user inputs?

Chuck Vought wrote:

wont that just continue to overwrite the last names created?

How do I create the array fo strings...

string firstname[20];

vector<string> firstname;

Chuck Vought wrote:

...or is that the number of different names that will be put into the array?

Chuck Vought wrote:

i have never done anything with vectors so option 1 looks better.

Chuck Vought wrote:

so when i set my cout statement to display each firstname would firstname[0] be name1, firstname[1] be name 2 , etc.

Below is what i am trying to do. Does it appear that i am oon the right track anyways.

Chuck Vought wrote:

name += letters[i%2][rand()%letterlen[i%2]];

name[0] = toupper(name[0]);

Chuck Vought wrote:

firstname[j]=firstname;

firstname[j] = name;

cout<< firstname[i];
