Thread: problem with variables

Code:

Set_randWord(22)

is picking a rand() value wich is used for rand element index from a string array, that holds many words. 22 is just the maxoffset of rand().

Code:

Get_randWord

is returning the picked word

So this first code is getting the lenth of a string and randWord without a problem. Also it prints its elements in the right way.

Code:

Set_randWord(22);    
    int len = Get_randWord().size();
    
    cout << len << endl; //<-- lenth of word is OK
    cout << Get_randWord() << endl; //<-- return a word is OK
    
    for (int i = 0; i < len; i++){
        hiddenWord[i] = '_'; //<-- hiddenWord declared in the class .h
        cout << hiddenWord[i] << " ";
    }
    hiddenWord[len] = '\0';

So the second code, the only difference is that the lenth variable of word is previously declared in the class.h

Code:

Set_randWord(22);
    lenofWord = Get_randWord().size(); //<-- lenofWord declared in .h


    cout << lenofWord << endl; //<-- lenth of word is OK
    cout << Get_randWord() << endl; //<-- return a word is OK


    for (int i = 0; i < lenofWord; i++){
        hiddenWord[i] = '_';
        cout << hiddenWord[i] << " ";
    }
    hiddenWord[lenofWord] = '\0';

In the second code i get exactly 195 '_' characters no matter how ,uch the lenth of the word is or the random word itself, 195 '_' are printed.
The difference i noticed is only that i change

Code:

len

with previously declared

Code:

int lenofWord
