C Program To Find Special Symbol or Not using Conditional Operator

Using Conditional / Ternary Operator determine, whether a character entered through the keyboard is a Special Symbol or not.

Note: ASCII values start from 0 to 255. So we have total of 266 ASCII values.

ASCII Code for Special Symbols
0 – 47
58 – 64
91 – 96
123 – 255

Ternary / Conditional Operator General Form

(expression_1) ? (expression_2) : (expression_3);

expression_1 is a comparison/conditional argument. expression_2 is executed/returned if expression_1 results in true, expression_3 gets executed/returned if expression_1 is false.

Ternary operator / Conditional Operator can be assumed to be shortened way of writing an if-else statement.

Expected Output for the Input

User Input:
Enter a Character
$

Output:
Character Entered Is a Special Symbol

Logic To Find Special Symbol or Not using Conditional Operator

Using Conditional Operator we write the condition, if user entered character is in between or equal to ASCII values 0 – 47 or 58 to 64 or 91 to 96 or greater than or equal to 123. We use Relational Operator and Logical Operators to accomplish the task.

If the condition in expression_1 is true, then whatever code is present in expression_2 gets executed. If condition is expression_1 is false then the code present in expression_3 gets executed.

Source Code: C Program To Find Special Symbol or Not using Conditional Operator

#include<stdio.h>

int main()
{
    char ch;

    printf("Enter a Character\n");
    scanf("%c", &ch);

    ( (ch >= 0  && ch <= 47) ||
      (ch >= 58 && ch <= 64) ||
      (ch >= 91 && ch <= 96) ||
      (ch >= 123) ) ?
      printf("Character Entered Is a Special Symbol\n") :
      printf("Character Entered Is not a Special Symbol\n");

    return 0;
}

Output 1:
Enter a Character
#
Character Entered Is a Special Symbol

Output 2:
Enter a Character
a
Character Entered Is not a Special Symbol

Output 3:
Enter a Character
Z
Character Entered Is not a Special Symbol

C Program To Display Zodiac Sign for Given Date of Birth

Write a C program that receives month and date of birth as input and prints the corresponding Zodiac sign or Astrological sign or Sun Sign based on the following table:

Sun Sign	From – To
Capricorn	December 22 – January 19
Aquarius	January 20 – February 17
Pisces	February 18 – March 19
Aries	March 20 – April 19
Taurus	April 20 – May 20
Gemini	May 21 – June 20
Cancer	June 21 – July 22
Leo	July 23 – August 22
Virgo	August 23 – September 22
Libra	September 23 – October 22
Scorpio	October 23 – November 21
Sagittarius	November 22 – December 21

Logic To Display Zodiac Sign for Given Date of Birth

Example, for Sun sign Capricorn, date lies between December 22 – January 19. So using &&(AND) and ||(OR) operators:

(month == 12 && day >= 22) || (month == 1 && day <= 19)

months

Expected Output for the Input

User Input:
Enter your birth month(1-12)
4
Enter your birth day
22

Output:
Your Zodiac Sign based on your Birth date is Taurus

    if(a > b)
    {
        printf("Biggest of %d and %d is %d\n", a, b, a);
    }
    else
    {
        printf("Biggest of %d and %d is %d\n", a, b, b);
