C Program to Find ASCII Value of a Character

In C programming, a character variable holds ASCII value (an integer number between 0 an 127) rather than character itself. You will learn how to find ASCII value of a character in this program.

To understand this example, you should have the knowledge of following C programming topics:

A character variable holds ASCII value (an integer number between 0 and 127) rather than that character itself in C programming. That value is known as ASCII value.
For example, ASCII value of 'A' is 65.
What this means is that, if you assign 'A' to a character variable, 65 is stored in that variable rather than 'A' itself.

Program to Print ASCII Value

#include <stdio.h>
int main()
{
    char c;
    printf("Enter a character: ");

    // Reads character input from the user
    scanf("%c", &c);  
    
    // %d displays the integer value of a character
    // %c displays the actual character
    printf("ASCII value of %c = %d", c, c);
    return 0;
}

Output

Enter a character: G
ASCII value of G = 71

In this program, user is asked to enter a character which is stored in variable c. The ASCII value of that character is stored in variable c rather than that variable itself.
When %d format string is used, 71 (ASCII value of 'G') is displayed.
When %c format string is used, 'G' itself is displayed.

C Program to Find Factorial of a Number Using Recursion

C Program to Find Factorial of a Number Using Recursion Example to find factorial of a non-negative integer (entered by the user) using recursion. To understand this example, you should have the knowledge of following C programming topics: C Programming Functions C User-defined functions C Recursion The factorial of a positive number n is given by: factorial of n (n!) = 1*2*3*4....n The factorial of a negative number doesn't exist. And the factorial of 0 is 1. You will learn to find the factorial of a number using recursion in this example. Visit this page to learn, how you can find the factorial of a number using loop . Example: Factorial of a Number Using Recursion #include <stdio.h> long int multiplyNumbers ( int n ); int main () { int n ; printf ( "Enter a positive integer: " ); scanf ( "%d" , & n ); printf ( "Factorial of %d = %ld...

C Program to Check Leap Year

C Program to Check Leap Year This program checks whether an year (integer) entered by the user is a leap year or not. To understand this example, you should have the knowledge of following C programming topics: C Programming Operators C if...else Statement A leap year is exactly divisible by 4 except for century years (years ending with 00). The century year is a leap year only if it is perfectly divisible by 400. Example: Program to Check Leap Year #include <stdio.h> int main () { int year ; printf ( "Enter a year: " ); scanf ( "%d" ,& year ); if ( year % 4 == 0 ) { if ( year % 100 == 0 ) { // year is divisible by 400, hence the year is a leap year if ( year % 400 == 0 ) printf ( "%d is a leap year." , year ); else printf ( "%d i...

C "Hello, World!" Program

C "Hello, World!" Program A simple C program to display "Hello, World!" on the screen. Since, it's a very simple program, it is often used to illustrate the syntax of a programming language. To understand this example, you should have the knowledge of following C programming topics: C Input Output (I/O) Program to Display "Hello, World!" #include <stdio.h> int main () { // printf() displays the string inside quotation printf ( "Hello, World!" ); return 0 ; } Output Hello, World! How "Hello, World!" program works? The #include <stdio.h> is a preprocessor command. This command tells compiler to include the contents of stdio.h (standard input and output) file in the program. The stdio.h file contains functions such as scanf() and print() to take input and display output respectively. If you use printf() function ...
