Removing an element from an array

[DdavidDLT]

I have .txt with this data :

5
Z 14
R 12
G 20
R 5
R 6

my goal is to add same letters into one total sum, while removing the used colors. So I should get :

3
Z 14
R 23
G 20

I know how to remove one element from an array but it for some reason only removes 1 R even tho I've looped the for loop.

void skaityti_Faila(int& n, veliavos V[])
{
    ifstream in("duomenys.txt");

    in >> n;

    for(int i = 0; i < n; i++)
        in >> V[i].spalva >> V[i].kiekis;

    for(int i = 0; i < n - 1; i++)
        for(int j = i + 1; j < n; j++)
            if(V[i].spalva == V[j].spalva)
                V[i].kiekis += V[j].kiekis;

    for(int i = 0; i < n - 1; i++)
        for(int j = i + 1; j < n; j++)
            if(V[i].spalva == V[j].spalva)
            {
                n--;
                for(int k = j; k < n; k++)
                    V[k].spalva = V[k + 1].spalva;
            }

    in.close();
}

Edit : After watching tutorials, I found my mistake.

Use a std::map to accumulate similar values.
