Programming Language:C++ OOP

Text Analysis: The availability of computers with string-manipulation capabilities has resulted in some rather

interesting approaches to analyzing the writings of great authors. This exercise examines two methods for analyzing texts with a computer. You have to use char * for following exercises.

1. Write a function which remove punctuations marks (.~ ! @ # $ % ^ & * ( ) _ + = ; : / ?) from the paragraph.

Note: Remember

i) Output must only contain alphabets and space characters.

ii) There must be single space between two words.

void removePunctuation(char *str)

/* This function receives string (char*)

And remove punctuation marks.

*/

{

}

Example:

Input: To be, or not to be: that is the question:

Output: To be or not to be that is the question

2. Write a function that receives a string consisting of several lines of text (paragraph) and

returns an array indicating the number of occurrences of each letter of the alphabet in the

text.

void countLetters(char* str, int*& array, int & size)

/* Parameters:

Input:

Char* str: a multiline string. E.g., This is a test String

Output:

int *: arr should contain the frequency of characters given in sequence of original

character array.

i-e

Index 0 contains frequency of 'T' //case sensitive

Frequency of T is 1

Index 1 contains frequency of 'h'

Frequency of h is 1

Index 2 contains frequency of 'i'

Frequency of i is 3

Index 3 contains frequency of 's'

Frequency of s is 2

Index 4 contains frequency of ' '(space)

Frequency of is 4

Index 5 contains frequency of 'a'

Frequency of a is 1

Index 6 contains frequency of 't'

Frequency of t is 3
