Answer:

Following are the answer to this question:

Explanation:

Prototypical inheritance:

This inheritance is a part of the object-oriented programming, in the JavaScript, the prototype is also an instance of an entity, on this type of inheritance an object inherits another object directly, in which an instance could be composed of several sources which enable simple selective inheritance and a flat structure of delegation[[Prototype]].

Web accessibility using JavaScript:

In the website or web page, JavaScript is usually fully accessible if another script 's implementation has been device-independent, and the components are accessible to be used in assistive devices. It enables the developers to improve web page information, which helps in communication, data processing, and regulation, and it also helps in management.

Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times
otez555 [7]

Answer:

The program written in python is as follows

def countchr(phrase, char):

     count = 0

     for i in range(len(phrase)):

           if phrase[i] == char:

                 count = count + 1

     return count

phrase = input("Enter a Phrase: ")

char = input("Enter a character: ")

print("Occurence: ",countchr(phrase,char))

Explanation:

To answer this question, I made use of function

This line defines function countchr

def countchr(phrase, char):

This line initializes count to 0

     count = 0

This line iterates through each character of input phrase

     for i in range(len(phrase)):

This line checks if current character equals input character

           if phrase[i] == char:

The count variable is incremented, if the above condition is true

                 count = count + 1

The total number of occurrence is returned using this line

     return count

The main method starts here; This line prompts user for phrase

phrase = input("Enter a Phrase: ")

This line prompts user for a character

char = input("Enter a character: ")

This line prints the number of occurrence of the input charcater in the input phrase

print("Occurence: ",countchr(phrase,char))
