Answer:
Following are the code to the given question:
#include <iostream>//header file
using namespace std;
int NumberOfPennies(int ND, int NP=0)//defining a method that accepts two parameters
{
return (ND*100 +NP);//use return keyword that fist multiply by 100 then add the value
}
int main() //main method
{
cout << NumberOfPennies(5,6) << endl; // Should print 506
cout << NumberOfPennies(4) << endl; // Should print 400
return 0;
}
Output:
506
400
Explanation:
In the method "NumberOfPennies" it accepts two parameters that are "ND and NP" that uses the return keyword that multiply 100 in ND variable and add in NP variable and return its values.
In the main method it it uses the cout method that call the by accepts value in parameter and print its value.
Answer:
115200000 bits
Explanation:
Given Data:
Total Time = 3 minute = 3 x 60 sec = 180 sec
Sampling rate = 40,000 bits / sample
Each sample contain bits = 16 bits /sample
Total bits of song = ?
Solution
Total bits of song = Total Time x Sampling rate x Each sample contain bits
= 180 sec x 40,000 bits / sec x 16 bits /sample
= 115200000 bits
= 115200000/8 bits
= 14400000 bytes
= 144 MB
There are total samples in one second are 40000. Total time of the song is 180 seconds and one sample contains 16 bits. so the total bits in the song are 144 MB.
