Programming challenge description: the goal of this challenge is to design a cash register program. you will be given two decimal numbers. the first is the purchase price (pp) of the item. the second is the cash (ch) given by the customer. your register currently has the following bills/coins within it: 'penny': .01, 'nickel': .05, 'dime': .10, 'quarter': .25, 'half dollar': .50, 'one': 1.00, 'two': 2.00, 'five': 5.00, 'ten': 10.00, 'twenty': 20.00, 'fifty': 50.00, 'one hundred': 100.00 the aim of the program is to calculate the change that has to be returned to the customer.

answer:

yes that is right have a good day

answer:

a

hope this give me a and brainliest

answer:

you shouldn't gave have you all your points.

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
