error: expression must have integral or unscoped enum type when incrementally filling in vectors


error: expression must have integral or unscoped enum type when incrementally filling in vectors

hop of those help? I am trying to fill arrays starting at initial values (location in xyz space) and move forward in the space by a discrete step to fill a 3d box. , The problem stems from this line:
code :
vector<float> x_range[size], y_range[size], z_range[size];

wish of those help Your variable size is declared as: float size;
You can't use a floating point variable as the size of an array - it needs to be an integer value.
code :
float *temp = new float[(int)size];
   float *temp = new float[size];

    //Getting input from the user
    for (int x = 1; x <= size; x++){
        cout << "Enter temperature " << x << ": ";

        // cin >> temp[x];
        // This should be:
        cin >> temp[x - 1];
    }

will be helpful for those in need
I am able to read the R and the G values but I get an error when I read the G value.
code :
HDC dc = GetDC(NULL);
COLORREF rgb = GetPixel(dc, 1, 1);

BYTE rcolor = GetRValue(rgb);
BYTE gcolor = GetGValue(rgb);
BYTE bcolor = GetBValue(rgb);

ReleaseDC(NULL, dc);

this one helps. This is the inefficient, platform dependent code causing the issue. , Replace
code :
std::cout << "MONSTER (WARNING): ", X << std::endl; 
std::cout << "MONSTER (WARNING): " << X << std::endl; 
//                               ^^^^^^

I think the issue was by ths following , if doing work with integer number is not a problem for you than you can try this code-
code :
int n,i,ev=0;
int arr[150];

cin >> n;

for (i = 0; i < n; i++)
{
    cin >> arr[i];
}
for (i = 0; i < n; i++)
{
    if (arr[i] % 2 == 0)
        ev++;
}

around this issue So I am trying to make a program that will move all files of a certain type, from my downloads folder to the folder they are supposed to belong. , You need to change the way you concatenate two strings, to:
