Making non-English alphabets work

Kimmo · #1 17-May-2007, 06:06

Hi,

A friend of mine asked me to make a program that asks the user for a name and returns the value calculated based on the given name. The program assigns a value to each alphabetical character and finds a corresponding value for the characters in the name.

I solved this by making an array of chars ['a', 'A' ... 'z','Z','å','Å','ä','Ä','ö','Ö']. The program then makes an array of ints equal to the size of alphabet, which is 29. Then the program uses two for loops to test the characters in the name string against each one in the alphabet array. When the characters match, it assigns the corresponding value from the values array.

The following might clear up the explanation:

CPP / C++ / C Code:

int i, j;         
i = j = 0;
int pituus = strlen(Aakkoset);  // length of the alphabet array "Aakkoset"
for (i = 0; nimi[i] != '\0'; ++i)   // nimi = name string
{
    for (j = 0; j < pituus; j = j + 2)  // skip one letter at a time
    {
            if (nimi[i] == Aakkoset[j])   // test for non-capitals
            {
                summa = summa + arvot[j / 2];
                break;
            }
            else if (nimi[i] == Aakkoset[j + 1])  // test for capitals
            {
                summa = summa + arvot[j / 2];
                break;
            }
            else
            {}
    }
}

The question is is this a slow way of finding the corresponce? Would there be some more simple and effective way?

The actual problem I'm having, though, is that the program doesn't recognize the letters 'ä', 'ö' or 'å' from the Finnish alphabet (giving them no values). The DOS prompt in Win XP doesn't show them either, it displays 'õ' etc. instead. So how should I go about making the program work in this respect? Is this because of the compiler or because of Windows?

I'm using Bloodshed Dev-C++ if it matters.

Cheers.
