Code 1:
1. Write a c program to reverse a given number
2. C program to find reverse of a number
3. C program to reverse the digits of a number
4. Reverse of a number in c using while loop
#include<stdio.h>
int main(){
int num,r,reverse=0;
printf("Enter any number: ");
scanf("%d",&num);
while(num){
r=num%10;
reverse=reverse*10+r;
num=num/10;
}
printf("Reversed of number: %d",reverse);
return 0;
}
Sample output:
Enter any number: 12
Reversed of number: 21
Code 2:
1. Reverse very large or big numbers beyond the range of long int
2. Reverse five digit number c program
Logic is we accept the number as string
#include<stdio.h>
#define MAX 1000
int main(){
char num[MAX];
int i=0,j,flag=0;
printf("Enter any positive integer: ");
scanf("%s",num);
while(num[i]){
if(num[i] < 48 || num[i] > 57){
printf("Invalid integer number");
return 0;
}
i++;
}
printf("Reverse: ");
for(j=i-1;j>=0;j--)
if(flag==0 && num[j] ==48){
}
else{
printf("%c",num[j]);
flag =1;
}
return 0;
Sample output:
Enter any positive integer: 234561000045645679001237800000000000
Reverse: 8732100976546540000165432
Code 3:
1. C program to reverse a number using for loop
2. How to find reverse of a number in c
3. Wap to reverse a number in c
#include<stdio.h>
int main(){
int num,r,reverse=0;
printf("Enter any number: ");
scanf("%d",&num);
for(;num!=0;num=num/10){
r=num%10;
reverse=reverse*10+r;
}
printf("Reversed of number: %d",reverse);
return 0;
}
Sample output:
Enter any number: 123
Reversed of number: 321
Code 4:
1. C program to reverse a number using recursion
#include<stdio.h>
int main(){
int num,reverse;
printf("Enter any number: ");
scanf("%d",&num);
reverse=rev(num);
printf("Reverse of number: %d",reverse);
return 0;
}
int rev(int num){
static sum,r;
if(num){
r=num%10;
sum=sum*10+r;
rev(num/10);
}
else
return 0;
return sum;
}
Sample output:
Enter any number: 456
Reverse of number: 654

ReplyDeleteits helping me a lost
ReplyDeleteu can avoid recursion by directly writing this code
ReplyDeletewhile(num!=0)
{
r=num%10;
sum=sum *10 + r
num=num/10;
}
take num=12
ReplyDeletenow r=12%10=2
sum=0*10+2=2
num=12/10=1
now num becomes 1
r=1%10=1
sum=2*10+1=21
num=1/10=0 so now 0>0 does not satisfy
printf("%d",sum)
so reverse of 12 is 21
@raj this logic only possible for upto 9nums
ReplyDelete/*i think i hv a b8r code.....*/
ReplyDelete#include
main()
{
int a,b,c,d,e;
printf("Enter the Number to Find it's Reverse\n");
scanf("%d",&a);
while(a!=0)
{
b=a%10;
c=a/10;
printf("%d",b);
a=c;
}
}
kapil's prog is great and easy
ReplyDeleteit is good but not perfect
ReplyDeleteyours s good but
ReplyDeletein some case ther will some need to hav zero in 1st digit
like 1230 we need to get 0321
yours cant do that,..???
Hi sangeerth,
ReplyDeleteIn code 2 instead of
for(j=i-1;j>=0;j--)
if(flag==0 && num[j] ==48){
}
else{
printf("%c",num[j]);
flag =1;
}
Write only
for(j=i-1;j>=0;j--)
printf("%c",num[j]);
These programs to reverse a number are not workin in the case of numbers which ends with zeor . Please help. for example if we input 320 the reverse shows 23 only not zero at the beginning.
ReplyDelete@alida: because the reverse of 320 is 023 and the zero at the front of a whole number is ignored because it is not significant.

i am needs this programme.i hope you will help me......
ReplyDeleteWrite a program which adds two arrays with the help of their pointers.
ReplyDeleteUsing your method if u will calculate the reverse of 10 or 100 or 1000 and so on ...then it will return 1 and 1 and 1 respectively so on .it can not show 01 , 001 , 0001 as reverse.

thanks but can you logics for using this code i.e:

ReplyDeleteplz explain this condition ......
some programs have errors
