CHAR FUNCTION WITH RETURN

1

I have created a function which returns 0 when the string has do not have distinct characters returns 1 when it has …I THINK THAT ERROR IS IN DECLARATION OF FUNCTION. Please HELP

#include<bits/stdc++.h>
using namespace std;

char fun(char a[], int n)
{
int flag=1;
for(int i=0;i<n;i++){
for(int j=i+1;j<n;j++){
if(a[i]==a[j]){
flag=0;
return (0);
break;
}
}
}
if(flag==1){
return (1);
}
}
int main()
{
char str[50];
cin>>str;
fun(str, strlen(str));
return 0;
}

You mean it output no error messages? Great, then presumably it compiled successfully. You still haven’t actually told us what’s wrong nor why you need help :slight_smile:
