    printf("AND IF YOU COULD SHOW ME THE CORRECTION");
    array();
}



void array()
{
int check(int num, int array[4][4]) {
int i, j;

    for (i = 0; i < 4; i++) {
        for (j = 0; j < 4; j++) {
            if (array[i][j] == num) {
                return 1;
            }
        }
    }
   
    return 2;
}


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?

Well you have two main() functions.

And you're trying to declare nested functions.

Code:

---

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

http://cboard.cprogramming.com/c-pro...t-process.html
Read this, and learn to press "compile" every 5 to 10 lines of new code.
Not bash the keyboard for hours to craft something with many dozens of lines, only to find out that it's swamped with errors you can't cope with.

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

Go back and read your C book again.

Because you seem to be randomly typing and compiling at the moment, just to see what happens.

For example, you were supposed to fix the nested function, not mess about with the declarations

Code:

---

void array ( ) {
} // this is the end of a function

int check(int num, int array[4][4]) {
    int i, j;

    for (i = 0; i < 4; i++) {
        for (j = 0; j < 4; j++) {
            if (array[i][j] == num) {
                return 1;
            }
        }
    }
   
    return 2;
} // this is the end of a function

int main ( ) {  // just ONE of these
    int arr[4][4], result;
    array();  // call it
    result = check(1,arr);  // call it
    return 0;
}
