Scroll through a matrix and validate repeated numbers

I am doing a final work in the first semester of the BCC course and I need to do a Mega Sena algorithm with the following features:

  • Maximum of 10 players
  • Each player must bet a minimum of 6 numbers and a maximum of 15 numbers
  • Valid numbers range from 1 to 60
  • Bets must not be repeated

The language used is Portugol, but we use a specific platform created by students from the University, so there are small variations in the code semantics relative to the common Visualg.

My question is only about a specific part of the code that I could not solve the betting part not repeat. If the user bets the number 1, the number 1 can no longer be used by anyone. Follows image of the code.

I suppose the solution to this problem can be solved by going through the matrix completely and checking each bet, but I couldn’t find a working method for it.

Anyone who can help, feel free to use the C language itself.

    The requirement is even "if the user bets the number 1, the number 1 can no longer be used by anyone"? Strange that!

  • Well, that’s what I understood, but I may have misread it. The statement says "It should be noted that the numbers bet cannot be repeated and must be chosen from the values 1 to 60". I imagine I made a little mistake... Player 1 bet: 1,2,3,4,5,6.. he won’t be able to bet the 1 again, but other players can bet the 1, maybe...

  • Or maybe the restriction is that there can be no repeating numbers in the same bet (ex: 1 1 2 3 3), as in real mega sena.

  • I imagine that’s right, but I still haven’t been able to implement such validation correctly in the code.. I suppose I should go through the whole vector and check if the number is there, but every time I try, I get an error saying that the vector has not been initialized.

  • The method would be the same, but I can not help you with this code, because I know little of C and even less of Portugol. The error you quoted is from portugol or c compiler?

  • It’s from Portugol itself.

    Try to post code instead of code image. I don’t know if Portugol has Syntax Highlight, but maybe another language will do.

  • Calango itself already has Syntax Highlight. The words in blue are the reserved words.

Before the vector[counter1][counter2] receives the bet, make a loop (to...knife) to verify that the informed bet is already inside the vector. If so, ask the user to enter the number again.

Something like:

leia(apostas);

para (contador3 de 1 ate 15) faca
       se (vetor[contador1][contador3] = apostas)
          ir para (goto) leia(apostas);      
fimpara

  • With such an implementation, I get an error "The vector variable[1][1]' has not been initialized".

  • Try to reset the vector first. loop ate 2 loop ate 15 vetor[][] = 0;

  • Try to replace in the code above the following: for (counter3 from 1 to (counter2 - 1)) knife ... This ensures that you will never test the array slots that have not yet received wagering values (not initialized)

  • Unfortunately I keep getting "uninitialized vector" errors. I imagine there is some way to after reading the 6 numbers, check inside the vector if there are repeated numbers, but I’m also getting vector not initializing error.
