C/C++ :: Incrementing Letters Per Line And Restarting Code Every 10 Lines

This is a command line lotto program. My first problem is trying to increment letters per line of the array. So for example, if the user types: ./mega_million 10

The output would be something like:

Mega Million
________________Mega
A 17 30 32 33 38 30
B 14 21 23 45 52 16
C 03 08 17 42 44 30
D 01 11 27 35 45 29
E 07 12 16 32 46 06
F 17 39 50 52 53 44
G 13 32 49 52 53 39
H 16 41 53 54 55 11
I 14 45 46 53 54 28
J 36 37 42 53 55 39

Here's the code I have written so far:

int main(int argc, char *argv[]) {
void rowLetters(char);
void generator(int[]);
void bubble_sort(int[],int);
string to_s(int);
string pad_zero(int);

[Code] ....

The second problem is splitting the output.. displaying 10 lines each ticket. So for example, if the user types: ./mega_million 12

The output would be something like:
Mega Million
