Question

Hello i have a program to take make and im having difficulty making it. This is to be done in C language.

If possible can this be done with using an Array. Thank you

Bingo Card Generator

Write a program that will

prompt the user for the number of players (maximum of 5)

prompt the user for the number of cards to generate for each player (maximum of 10)

for each card for each player, generate a valid bingo card (5 columns and 5 rows, here are some images of bingo cards

provide a menu for the user to select

which user/bingo card to display

to run a histogram on the bingo cards generated to see how many times each number between 1 and 75 appeared

Grading:

35 points for style per @10

10 points for appropriate prompts to get input (number users, number cards, info about which card to print)

10 points reading in input from user (number users, number cards, info about which card to print)

15 points generation of valid bingo cards

appropriate values in each column (B: 1-15, I: 16-30, ...)

no repetition of values in a column

free space in the middle of the card

15 points printing bingo cards to screen

10 points histogram
