Task: Displaying a String

Navigate to tasks/string-print/support/.

To display a string, we can use the internal macro PRINTF64. Alternatively, we can use a function such as puts(). In the file print_string.asm, displaying a string using the PRINTF64 macro is implemented.

Following the example of the hello_world.asm file, implement string display using puts as well.

If you’re having difficulties solving this exercise, take a peek at hello_world.asm.

After you consider your implementation complete, it is recommended to first run it manually in order to assess its correctness. In order to do so, enter the support/ directory and run:

make

If your code successfully compiled, you can then run the binary like so:

./print_string

To fully test the implementation, enter the tests/ directory and run:

make check

In case of a correct solution, you will get an output such as:

./run_all_tests.sh
test_print_simple                ........................ passed ...  33
test_print_special               ........................ passed ...  33
test_print_long                  ........................ passed ...  34

Total:                                                           100/100
