Trouble sorting an array

[spano693]

My program is supposed to create a matrix and add edges and vertices to the matrix, but I have one function, degreeSequence( ), that takes the array sequence and is supposed to output the degree sequence of the matrix. However, when my function goes to sort it and output it, it turns all the values that are supposed to be 2 into 55. Can anyone help?

int* graphType::degreeSequence()
//Function: returns array of integers representing the degree sequence for the graph
//Pre: graph and array are initialized
//Post: returns degree sequence array
{
    for(int i = 0; i < numberOfVertices; i++){ //loop to order array from largest to smallest
        for(int j = 1; j < numberOfVertices; j++){
            if(sequence[i] < sequence[j]){
                int placeholder; //holds value of sequence[i]
                sequence[i] = placeholder;
                sequence[i] = sequence[j];
                sequence[j] = placeholder;
            }
        }
    }

    for(int i = 0; i < numberOfVertices; i++){
        cout << sequence[i] << '\t';
    }
    cout << endl;
    return 0;
}

That's my function that sorts and outputs the array

thank you in advance!

The trouble is here:

sequence[i] = placeholder;  <-----!!!
                 sequence[i] = sequence[j];
                 sequence[j] = placeholder;

what do I do to correct it?

Never mind I'm an idiot. I read right over that. Thank you very much.
