Arrays In Calculation C++

Question

You are given an array of doubles of items in a store that have different prices (see template).
Write a program that takes the "percent off" discount as input and outputs discounted item prices on one line in the same sequence you are given, separated by a space (" ").

my code:

int main() {
double items[] = {500, 12.4, 94, 45, 3, 81, 1000.9, 85, 90, 1, 35};
double discount = 0;
//your code goes here
for (double x = 0; x < 11; x++){
cin >> discount;

discount = items[x]-items[x]*discount/100;
}
cout << discount << endl;

I don't understand how this won't calculate. I keep getting error that says "error: invalid types 'double [11][double]' for array subscript". I don't know what this means at all. I keep trying to google it but I cannot find anything that helps me solve this.

Answer 1

Yes @Guillem Padilla is right. Arrays only accept integer numbers as their subscript, so you should define x with "int" type, not "double"

Answer 2

You shouldn’t declare x as a double, but as an Integer

Answer 3

you are missing " " at the end of the it goes after the hundred take out the break and out << "space";
