Question

Write a function to show a character's description.

write a function that takes an unsigned character c as a parameter and prints c's description.

The description of 'a' is just a. But the description of '\n' (the newline character) should be \n, or some other desriptive name, such as newline. Use descriptive names for the tab ('\t') and space characters as well.

For an unprintable character whose integer code is m, use description \m. For example, the character with code 127 will have description "\127".

To check whether a character is printable, #include <cctype>. Then isprint(c) is true if character c is printable and is not a white-space character. Pass isprint a nonnegative integer code or an unsigned character, since it uses the character as an index in an array.

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

#include <iostream>

#include <cctype>

using namespace std;

//method to print the description of an unsigned char

void printDescription(unsigned char c){

                //identifying the character

                if(c=='\n'){

                                cout<<"newline"<<endl;

                }else if(c==' '){

                                cout<<"space"<<endl;

                }else if(c=='\t'){

                                cout<<"tab"<<endl;

                }else if(isprint(c)){

                                //printable character, just printing it

                                cout<<c<<endl;

                }else{

                                //not printable, just displaying a \ before the integer code of character

                                int code=c;

                                cout<<"\\"<<code<<endl;

                }

}

int main() {

                //testing the method using multiple test cases

                printDescription('a'); //a

                printDescription('Z'); //Z

                printDescription(' '); //space

                printDescription('\n'); //newline

                printDescription('\t'); //tab

                printDescription(180); // \180

                printDescription(65); //should print 'A'

                printDescription(64); //should print @

                return 0;

}

/*OUTPUT*/

a

Z

space

newline

tab

\180

A
