Question

int reversed_number(int number){

  int reversed = number;

  //TODO: if input is 12345, return 54321

  return reversed;

}

I need a C code that reverses the input please.

Answer 1

//C program

#include<stdio.h>
//function to reverse the number
int reversed_number(int number)
{
  //variable declaration
  int reversed = number;
  int rev=0,remainder;
  //while loop to reverse the number
  while(reversed!=0)
  {
    remainder =reversed%10;
    rev = rev*10 + remainder;
    reversed = reversed / 10; 
  }
  reversed = rev;
  return reversed;//return reversed number
}
int main()
{
  int number;
  //user input for number to be reversed
  printf("Enter a number:");
  scanf("%d",&number);
  //returned reversed number  stored in reversed
  int reversed = reversed_number(number);
  printf("Reversed number is:%d ",reversed);//print the reversed number
}

Output::
