Why my code is wrong?

#1

#include
using namespace std;
void lexographical(int &k,string *temp){
string str;
for(int i=1;i<k;i++){
for(int j=i+1;j<=k;j++){
if(temp[i]>temp[j]){
str=temp[i];
temp[i]=temp[j];
temp[j]=str;
}
}
}
return;
}
void permute(char *a,int i,string *temp,int &k){
if(a[i]==’\0’){
char s[1000];
if(a>temp[0]){
k++;
temp[k]=a;
}
return;
}
for(int j=i;a[j]!=0;j++){
swap(a[i],a[j]);
permute(a,i+1,temp,k);
swap(a[i],a[j]);
}
}
int main(){
char a[1000];
int k=0;
string temp[10000];
cin>>a;
temp[0]=a;
permute(a,0,temp,k);
lexographical(k,temp);
for(int i=1;i<=k;i++){
cout<<temp[i]<<endl;
}
if(k==0){
cout<<a;
}
return 0;
}
