C program find to the largest three number using pointer


C program find to the  largest   three number  using pointer

 In this program i have three integers n1,n2 or n3 . i assigned the address  of three  to three pointer p1 ,p2 or p3. Now   i  started the comparison on the value stored  at the address pointer.


                       Algoritham

  1. Start 
  2. Read a number to be compare as n1 ,n2 or n3.
  3. check if n1 is largest then n2.
  • if condition is true , then check if n1 is largest than n3.
  • if condition is true , then print largest number is n1.
  • if condition is false, then  print largest number is n3.
      4. If condition is  false , then check if n2 is largest than n3 
      a .  If condition is true , then print n2 is largest number .
      b.  If condition is false , than print n3 is largest number. 
      
       5.  End.

                 PROGRAM



#include <stdio.h>
#include <stdlib.h>
int main(int argc, char** argv)
{
int n1, n2,n3;
int *p1, *p2, *p3;
printf("enter first number: ");
    scanf("%d",&n1);
     printf("enter second number: ");
    scanf("%d",&n2);
     printf("enter third number: ");
    scanf("%d",&n3);
    p1 = &n1;
    p2 = &n2;
    p3 = &n3;
    if(*p1> *p2)
    {
        if(*p1 > *p3)
        {
            printf("%d is the largest number", *p1);
           
        }
        else
        {
            printf("%d is the largest number", *p3);
        }
        }
    else
    {
        if(*p2 >*p3)
        {
            printf("%d is the largest number", *p2);
        }
        else
        {
            printf("%d is the largest number", *p3);
           
        }
    }
  
    return (EXIT_SUCCESS);
}



OUTPUT
C program find to the largest three number using pointer

Q1 Write a c program to check a voting AGE condition Given age of someone and that we ought to check whether person is eligible for voting or not. To check that someone is eligible for voting or not, we'd like to examine whether or not person’s age is bigger than or up to eighteen. For this we tend to are reading age in a very variable a and checking the condition a>=18, if the condition is true, "person are eligible for voting" else no. #include <stdio.h> #include <stdlib.h> int main(int argc, char** argv) {         int a;     printf("ENTER A AGE\n");     scanf("%d",&a);     if (a>=18)     {         printf("YOU CAN VOTE");             }     else     {         printf("YOU CAN'T VOTE...
