60 sec. = 1 min.
3,600 sec = 1 hr.
(60 sec x 60 minutes) 86,400 sec= 24 hr.
(3,600 x 24) Given : 16,000 (bytes per seconds, for mp3 )
86,400 X 16,000 = 1,382,400,000 bytes for 24 hrs.
1,382,400,000 = 1,382.4 mega bytes (Mb.) for 24 hrs of music
Looking for how many days are in 1,000,000 Mb.
1,000,000 / 1,382.4 = 723.379629 Days worth of music.
Answer:
The explanation to this question is given below in the explanation section.
Explanation:
#include <iostream>
#include <string>
using namespace std;
int main()
{
int score;
cout << "Enter Score: \n";
cin>>score;
if (score == 100)
//whether the value of the score variable is equal to 100
{
cout << "Perfect ";
//If so, it should print “Perfect”
}
else
{
cout << "Nice Try ";
}
}
<u>Answer:</u>
<em>int fNumber,scndNumber = -1, </em>
<em>dup = 0;
</em>
<em>do {
</em>
<em>cin >> fNumber;
</em>
<em>if ( scndNumber == -1) {
</em>
<em>scndNumber = fNumber;
</em>
<em>}
</em>
<em>else {
</em>
<em>if ( scndNumber == fNumber )
</em>
<em>duplicates++;
</em>
<em>else
</em>
<em>scndNumber = fNumber;
</em>
<em>}
</em>
<em>} while(fNumber > 0 ); </em>
<em>cout << dup;
</em>
<u>Explanation:</u>
Here three variables are declared to hold the first number which is used obtain all the inputs given by the user, second number to hold the value of <em>last encountered number and “dup” variable to count the number of duplicate values.</em>
<em>“Do-while”</em> loop help us to get the input check whether it is same as previous input if yes then it <em>adds to the duplicate</em> value otherwise the new previous value if stored.
