Why won't the grid generate?

Hello! Trying to figure out why my grid for my memory game won’t generate, I have all the code ready and it compiles. Heres my code…

void Generate(int grid[5][6]);
void display(int grid [5][6],int matched [5][6]);
int main()
{
int grid[5][6];
int matched[5][6];

int     i=0, j=0;
int     r = r % 5;
int     c = c % 6;

// Generate the matched grid
for (i=0; i<5; i++)
{
for (j=0; j<6; j++)
{
if (i==0 || j==0 || i==j)
{
matched*[j] = 0;
} // end of if

        else
        {
            matched*[j] = 1;
        } // end of else
        
    } // end of for j
    
} // end of for i

// Display the grid
// Display(grid, matched);

 system("pause");

} // end of main()

// Generate the grid
Generate(grid);
// Algorithm for Program 5

void Generate(int grid[5][6])
{
int row, column = 0;
int r = 0, i = 0, j = 0;
// Fill grid with value 0

// Loop through rows
for ( i = 0; i &lt; 5; i++ ) 
{

    // Loop through the columns
    for ( j = 0; j &lt; 6; j++ )
    {
        
        // Store the value 0 at the current position
        grid*[j] = 0;    
    }// end of loop
    
}// end of loop

srand(time (NULL));

// Loop 15 times
for (i=0; i<15; i++)
// Generate a random number 1 - 99
r = rand();
r = (r - 0) * (100 - 1) / (RAND_MAX - 0) + 1;

// Loop as long as position picked contains a value
do
{
    // Pick a random row
    row = rand() % 5;
    // Pick a random column
    column = rand() % 6;
    
} while (grid [row] [column] !=0);// end of loop

// Store the value at the chosen location
grid[row] [column] = r;

// Loop as long as position picked contains a value
do
{
    // Pick a random row
    row = rand() % 5;
    // Pick a random column
    column = rand() % 6;

} while (grid [row] [column] !=0);// end of loop
{
// Store the value at the chosen location
grid[row] [column] = r;

}// end of loop
}// end of function

void display(int grid [5][6],int matched [5][6])
{
int i=0, j=0;
for (i = 0; i < 5; i++)
{
for (j = 0; j < 6; j++)
{
if (matched*[j] == 0)
{
printf("%c", 177);
} // end of if
else
{
printf("%i", grid*[j]);
} // end of else

        } // end of loop
    
    } // end of loop

} // end of function

now the “generate(grid);” is suppose to make my 5 by 6 grid appear, but when I compile its just a blank screen. So, how do I fix this?
