My goal is to read the first line of my colors.txt file and assign that integer value to `blue`. However, in my assignment I am instructed to use a char array `red` in order to assist in getting the first line of code. I have succeeded in doing so, but am having trouble with assigning it to `blue`.
int main() {
ifstream col;
char red[50];
int blue = 0;
col.open("colors.txt");
col.getline(red, 2, '\n');
cout << "Blue: " << red << endl;
}

So far I have thought about using the atoi function, but I'm not exactly sure if it will work in this case. Would it work if I copied the character array into the heap and then used a pointer to get the value?
