C program to print all ASCII characters and ASCII values/numbers
Problem Description:
Write a Program to print all ASCII characters and their ASCII numbers
Examples:
Our task to print all ASCII characters with their ASCII number
Here are few ASCII Characters and their ASCII numbers.
- For ASCII character Space the ASCII value is 32
- character ‘A’ (Capital A) the ASCII value is 65
- For ‘a’ (small a ) the ASCII value is 97
- For 0 (zero) the ASCII value is 48
What is ASCII Number:
ASCII stands for American Standard Code for Information Interchange. It is a character encoding format.
The characters are not directly stored into the memory, We use the encoding to store in efficient way.
ASCII one of the encoding formats. There are other encoding standards such as Unicode (UTF-8, UTF-16, UTF-32) and etc.
ASCII standards contains 255 characters. We are going try to print all these 255 characters ASCII Characters with their Numbers.
But only 127 ASCII characters are printable characters. To be exact the printable ASCII Characters from number 32 which is space to number 126 which is ESC. So our output might gives undefined values after 127 characters.
Program Logic:
As we know we have 255 ASCII characters. We are going to for loop iterate 255 times.
The basic idea is to pass the integer value to printf function and use the character format specifier ( %c ). So the printf function will cast the integer to ASCII character. and prints the output to the console.
We are going to repeat the above process for all ASCII number
from 0 to 255. At each iteration will make use of integer to character typecasting to print ASCII characters.
Print all ASCII characters and ASCII numbers Program:
|
1 2 3 4 5 6 7 8 9 10 |
include<stdio.h> int main() { Â Â Â Â Â Â Â Â int i; Â Â Â Â Â Â Â Â for(i=0;i<=255;i++) Â Â Â Â Â Â Â Â { Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â printf("ASCII value :%d \t and Ascii character :%c \n ",i,i); Â Â Â Â Â Â Â Â } Â Â Â Â Â Â Â Â return 0; } |
Print ASCII values Output:
All ASCII Characters with Respective ASCII Numbers. Please note few characters are not printable.
