Question

Create Code Using C program:
1. Write a function, reverse Digit, that takes an integer as a parameter and returns the number with its digits reversed. For example, the value of reverseDigit (12345) is 54321; the value of reverse Digit (5600) is 65, the value of reverse Digit (7008) is 8007 and the value of reverse Digit (-532) is -235.

Answer 1

/* program code */

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

int reverseDigit(int n) /* function definition */
{
int a,b=0;
while(n!=0)
{
a=n%10; // calculate the remainder of the number
b=b*10+a; // generate reverse mechanism
n=n/10;   // quotient of the number
}
return(b); // return the reverse value
  
}
main()
{
   int n,c;
   char ch;
   do{
   printf("\nEnter a number:");
   scanf("%d",&n);
   c=reverseDigit(n); /* function declaration and stores return value to c */
   printf("Reverse of the given digit is: %d",c);
   printf("\n\nWant to continue[if yes then press Y/y]:");
   fflush(stdin);
   scanf("%c",&ch);
}
   while(ch=='y' || ch=='Y'); //use do-while loop for taking numbers again if needed.
}
