Yes or No while loop for a 2d array doesn't print array in C-CodePudding

I'm new to c and don't really understand how 2d arrays work. When the code is executed it prompts for me to enter a course and then when the loop is broken the print statement doesn't show what I inputted.

    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>

    int main()

   {

   char courses[60][100];
   char ans ='y';
   int  i=0;
   int p,j;

   while (ans == 'y'){
   printf("Enter course:\n");
   for (p=0;p<j;p  )
   scanf("%s", &courses[p]);
   getchar(); 

   i  ;

  printf("Would you like to enter another course? (y or n) \n"); 
  ans = getchar();

 }
 printf("courses are %s",courses[p]);
 }

CodePudding user response：

int main()
{
    char courses[60][100];
    char ans ='y';
    size_t  i = 0;

    do
    {
        printf("Enter course:\n");
        scanf("
