Is My Code Wrong Here?. Check This Code!

#1

I created this code & it is producing the right output!. Can I use this instead of Prateek Bhaiya’s code?

#include

using namespace std;

int main()
{
char ch[20];
cin.getline(ch,20);
int j=0,i=j+1;
while(ch[j]!=’\0’){
if(ch[j]==ch[i])
i++;
else{
j++;
ch[j]=ch[i];
}
}
cout<<ch;

return 0;

}

yes, this code is perfectly fine as long as the input is at max 20 characters long. you can take char array of larger size if input is larger, everything else is correct.

thanks
