Question

I have 4 int arrays. They all have the same number of elements. Something like this:

int  ar1[] = {1,2,3,4};
int  ar2[] = {10,12,13,14};
int  ar3[] = {8,9,15,16};
int  ar4[] = {17,18,19,20};
int  big[][] ={ar1,ar2,ar3,ar4};  // I know this is messed up but here is where the question lies

Is there a way so that when I run a for loop:

int i;
for(i =0; i<4; i++){
    int x;
    for(x = 0; x<4; x++){
       printf(big[i][x]); // something like this   
    }
}

So that when this is executed, it prints out:

Array 1 : 1 2 3 4
Array 2 : 10 12 13 14
etc…..

Thanks.

Check this out: Multidimensional arrays in C and this Wikipedia page for the general information on multidimensional arrays in C.

Your code should work with this:

int* big[] = {ar1, ar2, ar3, ar4};
