Output of the array

#1

#include
using namespace std;
int main() {

int n;
cin>>n;
int a[100];
int n1,r,q,i;
n1=n;
i=0;
while(n1!=0)
{
  r=n1%10;
  n1=n1/10;
  a[i]=r;
  i++;  
}

n=sizeof(a)/sizeof(a[0]);
for (i=0;i<n;i++)
cout<<a[i]<<’\t’;
return 0;
}

this is my code for the Chewbacca and Number, HackerBlocks Tutorial
I wanted to put all the digits of a number in an array and then interchange the digits with 9-i.
In this process I wanted to display the array I am getting the array but after that, some unwanted garbage values are being displayed.


can I know how to get rid of the garbage values.

Hello @yyashu123,

The garbage values that you are getting are the initial garbage values stored in the array.
The reason those values are being displayed:
You are iterating the loop 100 times.

As, you have declared an array of size 100:
int a[100];
So, sizeof(arr)=4*100
and sizeof(arr[0])=4;
Hence, n=sizeof(a)/sizeof(a[0])=100

I have corrected your code:

Hope, this would help.
Give a like if you are satisfied.
