Jose, a top programmer at FOX, in a concerted effort to disrupt established viewing habits, is changing both the time slot and length of his network's most popular program, The Hockey Moms.

Jose will be using HAMMOCKING technique.

Explanation:

• Hammocking is a technique used in broadcast programming whereby an unpopular television program is scheduled between two popular ones in the hope that viewers will watch it. Public broadcasting also uses this as a way of promoting serious but valuable content. Hammocking may lead to situations where even if programs remain weak, audience rating will be high.
• The main theory in play is that audiences are less likely to change channels for a single time slot.
• Hammocking is a concept mainly limited to prime time, where "appointment television" is strong. However, there is a risk. If the middle show is too weak, the audience could change the channel altogether even if they “would have stayed if the two popular programs had formed a block

Answer:

The program to this question can be given as:

Program:

#include <iostream>  //header file

using namespace std;  //using name space.

int CountCharacters(char userChar,string userString) //define function.

{    

int count = 0;  //define variable

for (int i=0;i<userString.length();i++) //loop

if (userString[i]==userChar)  //if block

count++;  //increment the value.

return count;  //return value.

}

int main()  //main method.

{

   string userString= "Clanguage";  //define variable and assign value.

   char userChar = 'a';   //define variable and assign value.

   cout << CountCharacters(userChar,userString);  //calling function and print value.  

   return 0;  

}

Output:

2

Explanation:

• In the above C++ programming language program we define a function that is "CountCharacters". Inside function parameters, we pass two parameters that are "userChar and userString". The userChar is a char variable that holds single character value and userString is a string variable that holds a string value.
• In the function, we define an integer variable that is "count". This variable counts the match value and returns its value.
• To counts values, we define a loop in a loop we use if statement that counts the value that how many time it occurs in a string value and return its value.
• In the main method, we define these variables ("userChar and userString") and assign values that are "a and Clanguage " and call the function and print function return value.

Hardware, in Information Technology, is the physical aspect of computers, telecommunications, and other devices. It is any physical component that contains a circuit board or other electronics. An example is the screen on which you are using to read this, which brings us to option D

Software, by contrast, is a collection of instructions that enable the user interact with computer hardware. A Virus scanner is an example of a software program. A Virus scanner can also be known as anti-virus software. An anti-virus software scans and identifies viruses in a computer device.
