C++ program to print ASCII code for given digit and backspace.

Q28. Write a program to

• print ASCII code for a given digit.
• print ASCII code for backspace.

(Hint: Store escape sequence for backspace in an integer variable).

Ans(i).

#include<iostream.h>

#include<conio.h>  //for clrscr()

 

//Main Function

void main()

{

int num;

clrscr();  //for clear screen

cout<<“\n Enter a digit you want to print the ASCII value of: “;

cin>>num;

 

cout<<“\n The ASCII value of given number is: “<<(char)num;

getch();  //To hold the output screen

}

//End of main()

 

Output:

Enter a digit you want to print the ASCII value of: 97

The ASCII value of given number is: a

 

Ans(ii).

#include<iostream.h>  //for standard input and output

#include<conio.h>  //for clrscr()

 

//Main Function

void main()

{

char num;

clrscr();  //for clear screen

 

num=’\b’;

 

cout<<“\n The ASCII value of backspace is: “<<(int)num;

getch();  //To hold the output screen

}

//End of main()

 

Output:

 

The ASCII value of backspace is: 8
