take – Lua print(table) in string (taking all its values)

Question:

I created a system quickly to test a new variable, but I don't know how to get it to print the users inserted in the table, and when I go to print it it shows this: table: 0035AE18

My code:

Conta = {balance = 0}
Contas = {}
Senhas = {}
Inicial = 5000
function Conta:withdraw (v)
Conta.Balance = Conta.Balance - v
end

function Login()
io.write("Digite seu Usuario\n")
usuariol = io.read()
io.write("Digite sua senha\n")
senhal = io.read()

for i=0, #Contas do
for j=0, #Senhas do
if usuariol == Contas[i] and senhal == Senhas[j] then
io.write("Logado com sucesso!")
Cadastro()
end
end
end
end

function Cadastro()
io.write("Ola, seja bem vindo ao sistema de Banco 1.0 By Charles \n")
io.write("Deseja criar uma conta? \n")
resposta = io.read()

if resposta == "sim" or resposta == "Sim" then
io.write("Ok, informe seu nome de usuario \n")
usuario = io.read()
io.write("Informe sua senha \n")
senha = io.read()
io.write("Aguarde um instante!\n")
if #Contas == 0 and #Senhas == 0 then
table.insert(Contas, 1, usuario)
table.insert(Senhas, 1, senha)
else
table.insert(Contas, usuario)
table.insert(Senhas, senha)
end
Login()

elseif resposta == "tabela" then
print(#Contas)
print(#Senhas)
end
end

Cadastro()

The system works like this: it creates the account, then you log back in to create an account.

Let's suppose I created 3 accounts and then in the part "you want to create an account" I type "table" it will show me the number of accounts and passwords created.

But I want to display them not by size capacity but by string . Ex:

t = {'teste'}
print(t)

Console:

table: test

Answer:

I think this is what you want:

Conta = {balance = 0}
Contas = {}
Senhas = {}
Inicial = 5000
function Conta:withdraw (v)
    Conta.Balance = Conta.Balance - v
end

function Login()
    io.write("Digite seu Usuario\n")
    usuariol = io.read()
    io.write("Digite sua senha\n")
    senhal = io.read()

    for i=0, #Contas do
        for j=0, #Senhas do
            if usuariol == Contas[i] and senhal == Senhas[j] then
                io.write("Logado com sucesso!")
                Cadastro()
            end
        end
    end
end

function Cadastro()
    io.write("Ola, seja bem vindo ao sistema de Banco 1.0 By Charles \n")
    io.write("Deseja criar uma conta? \n")
    resposta = io.read()

    if resposta == "sim" or resposta == "Sim" then
        io.write("Ok, informe seu nome de usuario \n")
        usuario = io.read()
        io.write("Informe sua senha \n")
        senha = io.read()
        io.write("Aguarde um instante!\n")
        if #Contas == 0 and #Senhas == 0 then
            table.insert(Contas, 1, usuario)
            table.insert(Senhas, 1, senha)
        else
            table.insert(Contas, usuario)
            table.insert(Senhas, senha)
        end
        Login()

    elseif resposta == "tabela" then
        for i,v in ipairs(Contas) do
            print(v)
        end
        for i,v in ipairs(Senhas) do
            print(v)
        end
    end
end

See working on ideone . And on repl.it. Also posted on GitHub for future reference .

I used the most recommended technique to scan the entire array but you could use the same one you used to check if username and password are registered.

I think you should review how this data is stored.

Your code will bring memory issues (roughly speaking) to the way it's organized.

There are a few other problems but I think you'll still mess with it a lot.
