Matrici

Dupa mult timp revin cu un alt tutorial si anume cu matricile.

Din tutorialele precedente, ati observat ca C++ ne permite stocarea a mai multe numere intr-o singura variabila si anume intr-un tablou unidimensional, sau cum il stim cu totii: vectorul.Tot C++ ne permite stocarea a acelorasi numere, dar intr-o forma mai organizata si mai extinsa.Ca sa intelegeti mai usor,

o matrice poate fi considerata o lista de tablouri unidimensionale

.

Exemplu de matrici:

Declararea matricilor e la fel de simpla ca declararea vectorilor.O matrice are 2 dimensiuni: un numar de linii si un numar de coloane.Astfel in primul exemplu avem 3 linii si 3 coloane, iar a 2-a 3 linii si 4 coloane.


ATENTIE!
*La fel ca la vector, parcurgerea matricilor

unde
-dimensiunea1 este numarul liniilor
-dimensiunea2 este numarul coloanelor

Deci, in exemplul 1 vom considera o matrice de numere naturale si o vom declara astfel:

-tipul variabilei: unsigned int(matrice de numere naturale)
-numele variabilei(a matricii): a
-numarul de linii: 3
-numarul de coloane: 3
Astfel observam ca

In al doilea exemplu vom avea urmatoarea declarare:

You have to register to be able to see this link. Register HERE!If you are already a member please log in! If you still you are not able to see the link you need to activate your account or an administrator need to activate your account!

-avem 3 linii si 4 coloane
Asadar:

Acum ca am terminat partea de teorie si avem o idee despre ce inseamna o matrice, va voi invata sa cititi si sa afisati o matrice:

Am ales 3 linii si 5 coloane,iar programul va arata asa:


In urmatorul tutorial va voi invata despre diagonale si inca cateva lucruri.

Sper ca ati inteles si ca v-am fost de ajutor.Pentru intrebari lasati reply va rog.Multumesc pentru atentie si spor la programat!
