int i, j;

    for (i = 0; i < 4; i++) {
        for (j = 0; j < 4; j++) {
            if (array[i][j] == num) {
                return 1;
            }
        }
    }

int main() {
    int x,y,arr[4][4];
    int w;
    int ok=0;
    srand(time(NULL));

    for (x=0;x<4;x++)
    {
        for(y=0;y<4;y++)
        {
            if (x ==3 && y ==3) {
            
                printf("| \t");
            }
            else {
                ok =1;
                while (ok!=2) {
                    w = rand()%15+1;
                    ok = check(w, arr);
                }
                arr[x][y] = w;
                printf("|   %i\t",arr[x][y]);
            }
    
        }
        printf("|\n");
    }






return 0;
    }

What are you trying to do with this code?

soo should i define them seperatly
if sooo could please show me how to
iam kindda new to programming.

Your program, like all C programs, should have one and only one main() function:

Code:

#includes up here

//other functions? prototypes go here


int main() {

   // your code in here
  

   return 0;
} //end of main

Okay when I changed

int check(int num, int array[4][4]) {

to :

int check(int num)
int check (int array[4][4])

it didn't work

cause when I use void array() alone it builds succesfully

Please help me out here
