Move all x to end

#1

#include
#include
using namespace std;
int j=0;
void replace(char a[],char b[],int n,int i){
if(i==n){
cout<<b; }
if(a[i]!=‘x’){
b[j]=a[i];
j++;
}
replace(a,b,n,i+1);
}
int main(){
char a[100],b[100];
cin>>a;
int n=strlen(a);
replace(a,b,n,0);
int n2=strlen(b);
if(n2!=n){
cout<<‘x’;
n2++;
}
}
whats wrong in this code?

@tishya_goyal possible size of array ranges from 1 to 1000, and you are creating array of size 100 only.
