You need to pass in the address if the variable for scanf, using the & operator:
printf("Enter a value for Col: ");
scanf("%d", &nCol);
printf("Enter a value for Row: ");
scanf("%d", &nRow);
Also, you need to use \n at the end of each string you pass to printf,
otherwise the output buffer might not get flushed and the user might
not see the output.
Another advice is to learn to indent your code, it's very hard to
analyze it when everything is in one column.
