ASCII, abbreviation of American Standard Code For Information Interchange, a standard data-transmission code that is used by smaller and less-powerful computers to represent both textual data (letters, numbers, and punctuation marks) and noninput-device commands (control characters).

What is ascii code explain with example?
It is a code for representing 128 English characters as numbers, with each letter assigned a number from 0 to 127. For example, the ASCII code for uppercase M is 77. Most computers use ASCII codes to represent text, which makes it possible to transfer data from one computer to another.

How do you type Alt codes on a laptop?
On a Laptop you would hold down the Fn (function key) plus the ALT key and then type in numeric the ASCII code on the imbedded numeric keypad in the center of the laptop keyboard: The Hidden Numeric Keypad on Your Laptop . Alternatively you can click the NumLock key and just use the ALT Key. This should do the job.
How do I print ascii?
char c = ‘a’; // or whatever your character is printf(“%c %d”, c, c); The %c is the format string for a single character, and %d for a digit/integer. By casting the char to an integer, you’ll get the ascii value. To print all the ascii values from 0 to 255 using while loop.
How do I write ASCII in C++?
The program output is shown below.
- #include<iostream>
- using namespace std;
- int main ()
- {
- char c;
- cout << “Enter a character : “;
- cin >> c;
- cout << “ASCII value of ” << c <<” is : ” << (int)c;

- printf(“Enter a character”);
- scanf(“%c”,&ch); // user input.
- printf(“n The ascii value of the ch variable is : %d”, ch);
- return 0;
