C Program to Find ASCII Value of a Character

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.
 
ASCII value of a character
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 all Roots of a Quadratic Equation

C Program to Find all Roots of a Quadratic Equation This program accepts coefficients of a quadratic equation from the user and displays the roots (both real and complex roots depending upon the discriminant ).   To understand this example, you should have the knowledge of following C programming topics: C Programming Operators C if...else Statement The standard form of a quadratic equation is: ax 2 + bx + c = 0, where a, b and c are real numbers and a ≠ 0 The term b 2 -4ac is known as the discriminant of a quadratic equation. The discriminant tells the nature of the roots. If discriminant is greater than 0, the roots are real and different. If discriminant is equal to 0, the roots are real and equal. If discriminant is less than 0, the roots are complex and different. Example: Program to Find Roots of a Quadratic Equation #include <stdio.h> #include <math.h> int main () ...

C Program to Check Whether a Number is Positive or Negative

C Program to Check Whether a Number is Positive or Negative In this example, you will learn to check whether a number (entered by the user) is negative or positive.    To understand this example, you should have the knowledge of following C programming topics: C Programming Operators C if...else Statement This program takes a number from the user and checks whether that number is either positive or negative or zero. Example #1: Check if a Number is Positive or Negative Using if...else #include <stdio.h> int main () { double number ; printf ( "Enter a number: " ); scanf ( "%lf" , & number ); if ( number <= 0.0 ) { if ( number == 0.0 ) printf ( "You entered 0." ); else printf ( "You entered a negative number." ); } else printf ( "You entered a positive num...

C Program to Print an Integer (Entered by the User)

C Program to Print an Integer (Entered by the User) In this program, integer entered by the user is stored in a variable. Then, that variable is displayed on the screen using printf() function.   To understand this example, you should have the knowledge of following C programming topics: C Programming Constants and Variables C Programming Data Types C Input Output (I/O) Program to Print an Integer #include <stdio.h> int main () { int number ; // printf() dislpays the formatted output printf ( "Enter an integer: " ); // scanf() reads the formatted input and stores them scanf ( "%d" , & number ); // printf() displays the formatted output printf ( "You entered: %d" , number ); return 0 ; } Output Enter a integer: 25 You entered: 25 In this program, an integer variable  number is declared. ...
