2. Taking the input string from the user.

3. Passing those variables to for loop.

4. Finding the ASCII value of each character in the string. 

5. Printing the values for the characters.

6. End Program.

Program to print ASCII Value of All Characters.

In today’s program, we will first declare a variable in integer format having the value “i=0”. Then we will use a for loop printing all the values. There are 256 values in ASCII, and 128 of them are unique characters.

With the help of the below program, we can print the ASCII value of all characters.

Program Code:-

/**
 * C Program to find the ASCII Value of All Characters
 */

#include <stdio.h>
int main()
{
    //declaring the required value for the [program].
    int i;
    // i = it will hold the integer value for the loop controlling.
    
    /* Print ASCII values from 0 to 255 using the for loop */
    for(i=0; i<=255; i++) 
    {
        //printing the ASCII values of all the characters.
        printf("ASCII value of character %c = %d\n", i, i);
    }

    return 0;
}

/**

#include <stdio.h>

int main()

{

//declaring the required value for the [program].

int i;

// i = it will hold the integer value for the loop controlling.

/* Print ASCII values from 0 to 255 using the for loop */

for(i=0; i<=255; i++)

{

//printing the ASCII values of all the characters.

printf("ASCII value of character %c = %d\n", i, i);

}

return 0;

C Program to check character is a digit or not using IsDigit function

C Program to Check Character is Alphabet Digit or Special Character

In this tutorial, we will learn to create a C program that will Check the Character is Alphabet Digit or Special Character in C programming.

Prerequisites

Before starting with this tutorial, we assume that you are the best aware of the following C programming topics:

Operators in C Programming.
Basic Input and Output function in C Programming.

Conditional Statements in C programming.

What is a character?

The character is a single entity in the English language or in any word. These characters can be anything alphabets, digits, special symbols,

For Example:-

In the word “W3Adda@”, there are six characters, they are as follows

“W”
“3”
“A”
“d”
‘d’
‘a’
‘@’

Here,

“W” is an alphabet.

“3” is a digit.

“A, d, d, a” are also alphabets.

“@” is a Special Character.

    else 
    {
        /* Printing the output character as a special character */
        printf("'%c' is not a digit .", chr);
    }

    return 0;
}

/**

        //printing the output of the program as not in lower case.
        printf("'%c' is not in lower case alphabet.", chr);
    }
    else if(chr >= 'a' && chr <= 'z')
    {
        //printing the output of the program as lower case.
        printf("'%c' is a lower case alphabet.", chr);
    }
    else
    {
        //printing the output of the program as not a character.
        printf("'%c' is not an alphabet.", chr);
    }

    return 0;
}

{

/* declaring the variable required for the program. */

char chr;

/* Input character from user FOR THE PROGRAM*/

printf("Enter any character: ");

scanf("%c", &chr);

/* CHECKING THE INPUT FROM THE USER CHARACTER IF ITS LOWER CASE OR NOT */

if(chr >= 'A' && chr <= 'Z')

{

//printing the output of the program as not in lower case.

}

else

{

//printing the output of the program as not a character.

printf("'%c' is not an alphabet.", chr);

}

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

chr = it will hold the character value for the input.

Input character from the user.

Finding the character is in lower case or not.

Printing output for the program.
