C languge Could u plz add some notes to help me understandSo

Solution

#include <stdio.h>
#include<stdlib.h>

/*
Algorithm:
Given the number genrate a reverse of a number
if reverse and number are both equal than it is a palindrome.
  
Generating reverse number :
Example : 27
initialize reverse = 0
keep getting the last digit till the number become zero
  
Get the last digit of 27
7
reverse = reverse*10+lastDigit
reverse = 7
number = 27/10 = 2
  
Get the last digit of 2
2
reverse = 7*10 + 2
reversee = 72
number = 2/10 = 0
  
*/

void palindrome(int *x,int *n)
{
int reverse = 0;
int number = *x;
int lastDigit;
  
while(number!=0)
{
lastDigit = number%10;
reverse = reverse*10+lastDigit;
number = number/10;
}
  
if(reverse == *x)
*n = 1;
else
*n = 0;
  
return;
}

/*
Get all the digits using the same concept as above,
Sum all the cubes of last digits generrated from above process
and check for equality
*/

int armstrong(int *n)
{
int lastDigit,number = *n;
int sum = 0;
  
while(number!=0)
{
lastDigit = number%10;
sum = sum+lastDigit*lastDigit*lastDigit;
number = number/10;
}
  
if(sum == *n)
return 1;
else
return 0;
}

int main(void) {
   // your code goes here
int x;
  
//Input the number of element from user
printf(\"Enter x : \");
scanf(\"%d\",&x);
  
int res;
palindrome(&x,&res);
  
if(res == 1)
printf(\"%d is a palindrome.\ \",x);
else
printf(\"%d is not a palindrome.\ \",x);
  
printf(\"Enter a positive integer : \");
scanf(\"%d\",&x);
  
res = armstrong(&x);
if(res == 1)
printf(\"%d is a armstrong number.\ \",x);
else
printf(\"%d is not a armstrong number.\ \",x);
  
   return 0;
}

OUTPUT:

Enter x : 313

313 is a palindrome.

Enter a positive integer : 371

371 is a armstrong number.
