I have some questions about an academic paper in which the teacher asks to list, delete, insert and select matrices.
If someone could explain to me how to do thank you, follows down the slides of the work and what is requested, the part of the matrices is already done but I don’t even know how to do data management. In red is the theme on which I have doubts
.data
prompt: .asciiz "Digite o nº de linhas para a matriz1 :"
prompt2: .asciiz "Digite o nº de colunas para a matriz1 :"
prompt3: .asciiz "Digite o nº de colunas para a matriz2 :"
print1: .asciiz "Insira os valores da matriz1 : "
print2: .asciiz "Insira os valores da matriz2 : "
print7: .asciiz "\t"
print8: .asciiz "\n"
menu: .asciiz "1-Multiplicação\n2-Adicão\n3-Subtração\n"
menu2: .asciiz "1-Ler\n2-Adicionar\n3-Selecionar\n4-Apagar"
opcao: .asciiz "\nEscolha a opção : "
toWrite: .asciiz "Hello World was here"
