it compiles but in the output, it does not show anywhere I can input numbers. Have any idea?

.data

msg2:   .asciiz  "enter the number of rows: "
msg3:   .asciiz "enter the number of cols: "
msg4:   .asciiz "the value at the location is:  "
EOL:    .byte  '\n'

    Do you know how this code works?? It doesn't have any syscalls for input in the programming, so, yeah, it's not going to ask for input. – Erik Eidt Jul 09 '21 at 20:59
  • Yeah, I'm new to learning MIPS codes :( Can you help me where I can add a line for syscall to get inputs? – Marken Chris Jul 10 '21 at 07:40
  • Does this answer your question? [MIPS how to store user input and print it out](https://stackoverflow.com/questions/16205225/mips-how-to-store-user-input-and-print-it-out) – ggorlen Jul 11 '21 at 17:11
  • I recommend breaking the problem down into small steps. If all you need to do is add input, that's about 3 lines of code and is well documented. Once you have a simple program that reads and input, you can integrate that into whatever you're trying to achieve here (no specification was provided, but I assume you want to input and output a matrix).
