Some udfs for arrays in c

1D arrays
Printing 1 D arrays
void printArray (int *array,int size)
{
int i;
for (i = 0; i < size; i++)
     printf("%d",array[i]);
printf("\n");
}
2 D arrays 
Printing 2D arrays
void printArray(int **array, int m, int n)
{
           for(i = 0; i < nrows; i++)  
              for(j= 0; j < nrows; i++)  
                         printf("%d",array[i][j]);
}

Allocating and Deallocating 2 D Arrays 

/*   allocate2D

/*   function to dynamically allocate 2-dimensional array using malloc.

/*

/*   accepts an int** as the "array" to be allocated, and the number of rows and

/*   columns.

*/

void allocate2D(int** array, int nrows, int ncols) {

     

     /*  allocate array of pointers  */

     array = ( int** )malloc( nrows*sizeof( int* ) );

     

     /*  allocate each row  */

     int i;

     for(i = 0; i < nrows; i++) {

          array[i] = ( int* )malloc( ncols*sizeof( int ) );

     }

}

/*   deallocate2D

/*   corresponding function to dynamically deallocate 2-dimensional array using

/*   malloc.

/*

/*   accepts an int** as the "array" to be allocated, and the number of rows. 

/*   as with all dynamic memory allocation, failure to free malloc'ed memory

/*   will result in memory leaks

*/

void deallocate2D(int** array, int nrows) {

     

     /*  deallocate each row  */

     int i;

     for(i = 0; i < nrows; i++) {

          free(array[i]);

     }

     

     /*  deallocate array of pointers  */

     free(array);

     

}

/*   EXAMPLE USAGE:   

int** array1;

allocate2D(array1,1000,1000); //allocates a 1000x1000 array of ints

deallocate2D(array1,1000);    //deallocates the same array
