Scope of variables

  • Why do we have 2 variables with the same name in the program in question?
    •   
  • What value does the program print?
    •   
  • What should we do to get the value 15 printed?
    •   
  • Thinking about variable scope, how do we classify the variable in row 4? And how do we classify the variable of line 8?
    •   

    I have this code, and I need it to print the value 15, what should I do? Exercise of Portugol. 

    programa
{

    inteiro valor = 15

    funcao inicio()
    {
        inteiro valor = 10

        escreva("valor=", valor)
    }
}

    By logic and taking advantage of what you are trying to do, I believe the solution is as follows: 

    inteiro valor = 15

programa
{
    funcao inicio()
    {
        escreva("valor=", valor)
    }
}

    This variable valor only needs to be called once when it is in the global variable situation.
