A CD Player would be an example of a compound machine. A compound machine is one which contains several simple machines.
Simple machines are the following: Levers, pulleys, screws, and inclined planes.
I don't think that a screw or a pulley by itself could play a CD =P
Your answer is choice B, Compound Machine.

It would be helpful to use a: template
This keeps the fonts, colors, background, headers, footers, all the same in any (or all) the documents you create that you want to look like in a certain way...
Answer:
#include <iostream>
#include <cstdlib>
using namespace std;
int* integerArr( int number);
int main(){
int* address;
address = integerArr(5);
for ( int i = 0; i < 10; i++ ) {
cout << "Address of the integer array: ";
cout << *(address + i) << endl;
}
return 0;
}
int* integerArr( int number){
int myArr[number];
for (int i = 0; i < number; ++i) {
myArr[i] = rand();
}
int* ptr= myArr;
return ptr;
}
Explanation:
The C++ source calls the defined pointer function "integerArr" with an integer argument to declare arrays of dynamic length, in the main function of the program and the items of the array are printed on the screen.
The answer is A- Mobile Wallet
It can be used to pay for your purchases instead of using your actual card. It may be an app or it may be already built into the device. It is actually more convenient to others because you can just hold your device at the terminal when you will pay. Mobile Wallets may be smartphones or tablets.
