Answer:
a)
for(x=0;x<20;x=x+2)
cout<< x << ' ';
cout<< endl ;
<u>Output</u>
0 2 4 6 8 10 12 14 16 18
In this code we are initialing x with 0, check if it is less than 20, then printing the value 0.
Then we increment x value with 2 and check and print again until the x value tends to be equal or more than 20.
<u>C++ program for verifying</u>
#include <iostream>
using namespace std;
int main()
{
int x;
for( x=0;x<20;x=x+2)
cout<< x << ' ';
cout<< endl ;
return 0;
}
<u>Output</u>
0 2 4 6 8 10 12 14 16 18
(You can check on any ide for confirmation)
b)
i=10;
for (;i>0; i =i/2;)
cout<< i;
This code will produce error expected ‘)’ before ‘;’ token
for(;i>0; i =i/2;)
because for loop consist three parameters and in this loop there are 4 parameters.
If we remove semicolon after i/2,
for(;i>0; i =i/2)
then it will produce an output.

Answer:
Channel
Explanation:
Channel refers to a communication pathway, circuit, or frequency dedicated or reserved for a specific transmission.
1Gb = 1000Mb



4000Mb ÷ 1000Mb = 4Gb
Explained again:
Four 500 mb drives:
500 + 500 = 1000mb = 1Gb
500+500 = 1000Mb = 1Gb
1Gb+1Gb = 2Gb
plus the 2Gb flash drive:
2Gb + 2Gb = 4Gb
