Reverse the given Number Using Recursion Function In C




#include
int main(){
int num,rev;
printf("\nEnter a number :");
scanf("%d",&num);
rev=reverse(num);
printf("\nAfter reverse the no is :%d",rev);
return 0;
}

int sum=0,r;
reverse(int num){
if(num){
r=num%10;
sum=sum*10+r;
reverse(num/10);
}
else
return sum;
return sum;
}





Method 2


#include "stdio.h"

int reverse(int,int );

void main()
{
int no,rev=0;
printf("Enter a number..\n");
scanf("%d",&no);
printf("The reversed number is %d.\n",reverse(no,rev));
}

int reverse(int no,int rev)
{
if(no!=0)
return reverse(no/10,rev*10+no%10);
else
return rev;
}






Method 3



#include
main()
{
int a,i,n,b;
printf("Enter the no:");
scanf("%d",&a);
while(a)
{
b=a%10;
printf("%d",b);
a=a/10;
}
}

History Of C..

In the beginning was Charles Babbage and his Analytical Engine, a machine
he built in 1822 that could be programmed to carry out different computations.
Move forward more than 100 years, where the U.S. government in
1942 used concepts from Babbage’s engine to create the ENIAC, the first
modern computer.
Meanwhile, over at the AT&T Bell Labs, in 1972 Dennis Ritchie was working
with two languages: B (for Bell) and BCPL (Basic Combined Programming
Language). Inspired by Pascal, Mr. Ritchie developed the C programming
language.

My 1st Program...


#include
#include
void main ()
{
clrscr ();
printf ("\n\n\n\n");
printf ("\t\t\t*******Pankaj *******\n");
printf ("\t\t\t********************************\n");
printf ("\t\t\t\"Life is Good...\"\n");
printf ("\t\t\t********************************");
getch ();
}

Next Step...


#include
#include

void main ()
{
clrscr ();
printf ("\n\n\n\n\n\n\n\n");
printf ("\t\t\t --------------------------- \n\n");

printf ("\t\t\t | IGCT, Info Computers, INDIA | \n\n");
printf ("\t\t\t --------------------------- ");

getch ();

}

Hits!!!
