Answer 1

Right now the code prints the percentage and that's not question wants..

Do this inside for loop
cout << arr[x] × 1/100 × arr[x];

I am not an expert .. see if this works

Answer 2

#include <iostream>
using namespace std;

int main() {

double items []={500, 12.4, 94, 45, 3, 81, 1000.9, 85, 90, 1, 35};

int percent;
double discounted_price;

cin >> percent;

for (int x = 0; x < 11; x++) {
discounted_price=items[x]-items[x]*percent / 100;
cout<<discounted_price<<" ";

}

return 0;
}

And I don't even know why you got 8 likes lol ,people should understand that it's not a social media platform and only upvote a question that is really informative and helpful for others as well.

Answer 3

Detailed Explanation:

See on line #9

When the loop runs for first time,You are reassigning the variable percentage to the discounted price of item.

Now in next iteration of loop you don't have the percentage value that user inputted as you have replaced(reasssigned) it on line #9 when loop runned for first time

Answer 4

Quick Solution:

Replace the line #9 with :
cout<< percentage*arr[x]/100

and delete line #11

Answer 5

you forget discount also I think issue is data type u taken int for percentage and double for items in your percentage variable values will be stored in int form may be this is the issue tell your expecting output.

Answer 6

#include <iostream>
using namespace std;

int main() {
double items[]={500,12.4,94,45,3,81,1000.9,85,90,1,35};
int n,i;
double percent;
cin>>percent;
n=sizeof(items)/sizeof(items[0]);
for(i=0;i<n;i++)
items[i]=items[i]-(items[i]*percent/100);
for(i=0;i<n;i++)
cout<<items[i]<<" ";
return 0;
}
