Portugol expecting a value of the "real" type

Question

I have a problem in my pseudocode, when I run it informs that:

the data entry of the program expected a value of the 'real' type, but no value was informed or the value is of another type;

How to solve this?

programa
{
    funcao inicio()
    {
        real N1, N2, N3, MEDIA
        inteiro QTD, cont
        escreva("\nDigite a qualtidade de alunos que deseja calcular a media: ")
        leia (QTD)
        cont = 0
        (cont< QTD) faca
        {
            leia(N1)
            leia(N2)
            leia(N3)    
        } enquanto(cont< QTD)
        se (N2>=N3)
            MEDIA=(N1+N2)/2
        senao
            MEDIA=(N1+N3)/2
        se(MEDIA>=6)
            escreva("\nAluno aprovado, Media:\n", MEDIA)
        senao
            escreva("\nAluno reprovado, Media:\n ", MEDIA)
            {

            }       
    }
}

Answer 1

Your loop of repetition faça-enquanto is wrong, he’s like this:

(cont< QTD) faca
{
 leia(N1)
leia(N2)
leia(N3)    
} enquanto(cont< QTD)

While he should be like this:

faca
{
   leia(N1)
   leia(N2)
   leia(N3)    
   cont++  //incremento do contador
} enquanto(cont< QTD)

You should write the stop condition only after the enquanto in your code you had written the stop condition twice.

Another error you would encounter after fixing your loop loop is the counter that doesn’t increment, so you would be in an infinite loop

PS: Remember to code

Answer 2

There is an error of logic missing increment cont if not it will always be smaller want QTD

in that code add the line cont = cont + 1 after reading(N3)

  faca{
        leia(N1)
        leia(N2)
        leia(N3)    
 } enquanto(cont< QTD)

or your code will look like this:

    faca{
         leia(N1)
        leia(N2)
        leia(N3)    
        cont = cont + 1 //linha nova 
 } enquanto(cont< QTD)
