    Need Help....Simple Program

    Hello all, im pretty new to C++ been learning over the past couple weeks. The problem im having is this:

    Im writing code to promt the user to enter thier name, either first or last...doesnt matter.
    Well thats easy but the problem im having is that i need to prompt the user to enter a letter and then check the name for how many times that letter occurs...and then display that to the screen...does anyone know how i can do that??

    Ohh and its due thursday so yeah this is my last resort....

    I'm a relative newbie to C++ myself, but here is my suggestion. Have the user input the letter and store it in a char variable (with cin >> char_variable). Then have the user enter their name and store it in name (with cin.getline(name, 29, '\n')). Then use a FOR loop to cycle through the word and check if each letter is equal to the letter the user is looking for (char_variable). Each time you find a letter that is equal, increase the value of an integer variable (num) by one, and that variable will then be equal to the number of times that letter occurs in the word. Example:

    Code:
    int getLetterCount(name)
    {
    for (int x = 0; x < strlen(name); x++)
    {
      if (name[x] == char_variable)
      {
        num = (num + 1);
      }
    }
    return num;
    }
    Again, i am a newbie myself, so that may not be right, but it is my best suggestion.

    Yeah, that would work. Just make sure to declare and initialize num.

    yea, also you should think about how your function will get the information about the name and the character. either you could do what cjmdjm did and pass in the name, but then you have to prompt the user to input the letter from inside your function. OR you could prompt the user from main() and pass the name AND the character to be found to the function like this:
    Code:
    int getLetterCount(char name[], char letter_to_find)
    {
    ...
    }
    either way should work fine, whichever you want to do. i'd personally do what I just showed you but that's just me...

    and if you hadn't noticed, you should change your function to return int and not void, unless you're using that function to display how many times the character was found.
