Please identify the problem in my logic

#include
#include
using namespace std;

void replace(char a[],int i)
{
if(a[i]==’\0’||a[i+1]==’\0’)
{
return;
}

if(a[i]==a[i+1])
{
	int j=strlen(a);
	while(j>i)
	{
		a[j+2]=a[j];
		j--;
	}
	a[i+1]='*';
replace(a,i+2);	
}
replace(a,i+1);

}
int main() {
char string[10000];
cin>>string;
replace(string,0);
cout<<string;
return 0;
}

Following is very simple logic:

Also, the way you have shared your code has introduced many syntax errors to it.
Rather, share it using the online IDE.
