Answer:
Hi!
The following Javascript statement compares if num is 2 or 5 and increment num by 1 if true.
if ( num==2 || num==5)
num = num +1;
Explanation:
The operator == is used to compare if the operands are equal.
The operator || is OR.
- If at least one of the operands is true then return true.
- If all operands are false returns false.
if( num==2 || num==5)
<em> // if num is equal 2 or if num is equal 5</em>
num = num +1; <em>// adds 1 to num.</em>
Answer:
to check to see if some expression is true, and if it is do something, otherwise do something else. An if/else statement requires you to define an expression that evaluates to true or false.

Answer:
The solution code is written in Python
d = 1.5 + random.random() * 6
Explanation:
By presuming the Python random module is imported, we can use the <em>random</em> method to generate a random number. <em>random.random()</em> will give us a value in the range [0, 1). The ensure the lower limit is 1.5 instead of 0, we can add 1.5 to random.random()
This expression will give any value in range [1.5, 2.5)
To ensure the upper limit is set to 7.5, we tweak the previous expression to
- 1.5 + random.random() * 6
This expression will always multiply a random number from [0,1) with 6 and then only added with 1.5. This will always produce a random number that fulfill the inequality 1.5 ≤ d < 7.5

Check the explanation
Explanation:
public static int countMatching(String s, char c) {
int count = 0;
for (int i = 0; i < s.length(); i++) {
if (s.charAt(i) == c)
++count;
}
return count;
}
Method in a complete Java program
public class FizzBuzz {
/* sample run:
* z appears 2 time(s) in FIZZbuzz
*/
public static void main(String[] args) {
String s = "FIZZbuzz";
char c = 'z';
int count = countMatching(s, c);
System.out.printf("%c appears %d time(s) in %s%n", c, count, s);
}
// Put your countMatching() method here:
public static int countMatching(String s, char c) {
int count = 0;
for (int i = 0; i < s.length(); i++) {
if (s.charAt(i) == c)
++count;
}
return count;
}
}
z appears 2 time(s) in FIZZbuzz Process finished with exit code
Answer:
modulation
Explanation:
Modulation is the procedure of encoding data into electrical signals for transmission through a media. For transmission, binary information, denoted by a sequence of ones and zeros, should be translated to analog or digital electrical signals. The method converts data into electrical signals suited for transmission is known as modulation. Digital modulation is the transmission of binary signals zeroes and ones.
