Answer #1

/*

Your program is not printing because there are four errors in your program. But remember i have only checked the part of the code which is being executed and i have not checked the functions which has been commented out. I am listing out the errors along with the line no. below -

1. Line No. 23 - You cannot declare an integer array as an argument of main function. You need to declare it inside the main function or outside if you want to use it as global.

2. Line no. 138 - You have passed only 2 arguments to the function 'fillCardRand' which accepts 3 arguments. However there is no need of the variable 'num' that you have used as an argument while defining the function 'fillCardRand' as you have not used the variable inside the function. So i have removed it while correcting the code.

3. Line no. 146 - You have passed only 3 arguments to the function 'setValue' which accepts 4 arguments. You forgot to pass the array 'used' to the function 'setValue'.

4. Line no. 192 - You have only initialized the last element of the array 'used' to FALSE. By mistake you wrote 'used[MAXVAL] = FALSE' instead of 'used[col] = FALSE' inside the loop.

Below is the corrected code.
