NASM Assembly: 10-Shape Console Menu Integration

Task:

– Implement a simple console menu on NASM (x86_64) with a selection of 10 shapes.

– When a menu item is selected, the program should call the corresponding pre-existing drawing procedure and display the shape in the console.

What is already available:

– 10 separate NASM files with drawing procedures for each shape (rectangle, square, diamond, staircase, house, cross, star, pentagon, triangle, heart).

– Inside each procedure, the input of necessary parameters (size, color, etc.) and the drawing algorithm are configured.

What needs to be done:

1. Create a single file main.asm with sections .data, .bss, and .text.
2. Add an entry point label (_start) and organize the display of the text menu:

3. Read the user's choice (a digit from 1 to 10), verify input correctness, and in case of an error, display a message and terminate the program.
4. If the choice is correct, jump to the section (.do_shapeX), where the corresponding shape's drawing procedure will be inserted.
5. At the end of each procedure — a unified call to syscall exit(0).
6. Ensure that all labels and buffers inside the combined file have unique names to avoid conflicts.

Result:

– One file main.asm with the menu, input, switch, and 10 inserted procedures.
