random cards

[riyadhhossain01]

this is my function to generate random cards.

string facevalue[] = { "DA","DK","DQ","DJ","D2","D3","D4","D5","D6","D7","D8","D9","D10",
"HA","HK","HQ","HJ","H2","H3","H4","H5","H6","H7","H8","H9","H10",
"SA","SK","SQ","SJ","S2","S3","S4","S5","S6","S7","S8","S9","S10",
"CA","CK","CQ","CJ","C2","C3","C4","C5","C6","C7","C8","C9","C10"
};


string getcard() {

string card;
int cardvalue = rand() % ARRAY_SIZE(facevalue);
card += facevalue[cardvalue];
return card;
}


so my problem is that if i save these cards inside 4 different string vectors and each vector will take 7 cards.sometimes i get repeated cards. But i dont want it repeated.How can i do that? please help. plus give me the code because i am new to coding.

one option would be to remove each element from facevalue as they are "dealt out" to the individual vectors..

I think the best way to do this is by shuffling your cards - which is what happens in real life.

By shuffling, you're guaranteed unique cards with no duplicates, since all that's changing is their position. You're then free to draw as many cards as you please.

ok. But how do i do write it in codes?
