Can you print a string array?

We cannot print array elements directly in Java, you need to use Arrays. toString() or Arrays. deepToString() to print array elements. Use toString() method if you want to print a one-dimensional array and use deepToString() method if you want to print a two-dimensional or 3-dimensional array etc.

How to write a program with pointers in C?

If you have a pointer say ptr pointing at arr [0]. Then you can easily apply pointer arithmetic to get reference of next array element. You can either use (ptr + 1) or ptr++ to point to arr [1]. But wait before moving on to next program, there is another way to write the above program.

Which is better to print a string or putchar?

The printf function is very useful, but putchar is often better suited for single-character output. The reason is that printf has to, at runtime, parse the format string, apply the arguments and then emit the results, while putchar only has to pass a character directly to the output.
