Need help debugging my declared vectors in functions

int summation(const vector<int> total){
You're trying to add items to the end of a const vector (const is the qualifier it is complaining about you trying to discard)

total.at[0] at is a function. Use brackets to pass parameters to functions (i.e. total.at(0)

OP for reference:

Hi all,
I've seem to come to a roadblock in my computer code. Up to this point, I have everything running smoothly, except I keep getting the error "invalid types â<unresolved overloaded function type>[int]â for array subscript" three times for line 127 of my code. I am also getting this strange "error: passing âconst std::vector<int, std::allocator<int> >â as âthisâ argument of âvoid std::vector<_Tp, _Alloc>::push_back(const _Tp&) [with _Tp = int, _Alloc = std::allocator<int>]â discards qualifiers" error on lines 123, 124, and 125. I've scoured all over the forums but anything relating to these problems doesn't make sense to me. Any sort of help would be greatly appreciated! I am trying to create an int function to find the summation of the integers in three different vectors.
