ASCII to character conversion In C

Finding that a given number is even or odd, is a classic C program. We shall learn the use of conditional statement if-else in C.

Algorithm

Algorithm of this program is very easy −

START
      
   Step 1 → Take integer variable A
          
   Step 2 → Assign value to the variable

   Step 3 → Perform A modulo 2 and check result if output is 0
   
   Step 4 → If true print A is even
   
   Step 5 → If false print A is odd

STOP

Flow Diagram

We can draw a flow diagram for this program as given below −

Pseudocode

procedure even_odd()
   
   IF (number modulo 2) equals to 0
      PRINT number is even
   ELSE
      PRINT number is odd
   END IF

end procedure

Implementation

Implementation of this algorithm is given below −

#include<stdio.h>

int main()
{
   int a, b, temp;

   a = 25;
   b = 35;

   while(b != 0)
   {
      temp = b;
      b = a % b;
      a = temp;
   }

   printf("HCF : %d", a);
   return 0;
}

Output

Output of the program should be −

HCF : 5
