Write a program to find the reverse of a given number with help of function?

Answer 1

//Reverse of the Number

#include<stdio.h>

#include<conio.h>

int main ()

{

int num,mod,rev=0;

printf("Enter a number:");

scanf("%d", &num);

while (num>0)

{

mod=num%10;

rev=(rev*10)+mod;

num=num/10;

}

printf("Reverse of the given number: %d", rev);

getchar();

return 0;

}

// alternative solution based on reversing the alphanumeric representation of

// the number:

void rev(int me) {

char alpha[32];

sprintf(alpha, "%d", me);

for (const char* cp = alpha + strlen(alpha) - 1; cp >= alpha; --cp) {

putchar(cp); }

}

Answer 2

suppose you are given the number
9254

In order to reverse it, you must eliminate each value and reverse it.
For example,

9254 / 1000 = 9
9254 % 1000 = 254

then
254 / 100 = 2
254 % 100 = 54

then
54 / 10 = 5
54 % 10 = 4

and your final digit is 4.

I will leave it up to you to figure out how to implement this, but that is the algorithm for extracting digits.
It should be clear how to use loops to abstract this problem into a "reverse" function.

Answer 3

#include

Main()

{

Int num,r,rev=0;

Printf("enter a number");

Scanf("%d",&num);

While(num>0)

{

r=num%10;

rev=rev*10+r

num=num/10;

}

Printf("%d",rev);

}

Answer 4

#include <stdio.h>

void main() //Defining main function

{

int number, modulus, reverse; //Integer Declaration

reverse = 0; //Initialization

printf("Enter a number \n");

scanf("%d", &number);

while(number != 0)

{

modulus = number % 10;

reverse = (reverse * 10) + modulus;

number =number / 10;

}

printf("The reversed number is %d", reverse);

getch();

}

Answer 5

/*C Program to Enter 5 Number at a time & Display them in Reverse Order of the input*/

#include<stdio.h>

#include<conio.h>

void main()

{

int i, x[5];

clrscr();

for (i=0;i<5;i++)

{

printf("Enter the number\n");

scanf("%d",&x[i]);

}

printf("\nThe reverse order is\n");

for (i=4;i>=0;i--)

{

printf("\n%d",x[i]);

}

getch();

}

Answer 6

1. Convert the number to a string.

2. Reverse the characters

3. Drop any leading zeros on the new string
