Need help with the conversion

Code:

---

#include <iostream>
#include <cstdlib>


using namespace std;
void search(char a,char b[], int size);


int main()
{
    int j = 0;
    char *a,*b;
    int size = 5;
    a = new char[size];
    b = new char;
    int i;
   
    for(int i = 0 ; i < size ; i++)
    cin>>a[i];
      for( i = 0; i < size; i++)
      if(!search(a,b,size))    //This is my main problem of conversion
      {
            b[j]= a[i];
              j++;
      }
    for(int i= 0; i < j; i++)
    cout>>b[i];
     
                       
   
   
    cout<<endl;
   
      system("PAUSE");
      return 0;
}
void search(char a,char b[], int size)
{   
    bool found = false;
    for(int i = 0 ; i < size ; i++)
              if (a == b[i])
              found = true; 
              return found;   
}

Here is my code and I need help from the conversion. Even I try to pre-write the code to avoid that mistake but it still appear in another line, and I don't know how to fix this. Any suggestion?????

Here a few errors in your program :

Code:

---

void search(char a,char b[], int size);

---

Change the return type to bool.

Code:

---

if(!search(a,b,size))    //This is my main problem of conversion

---

Your function takes in 'char' as the first argument. a is of type 'char*'. I feel that you have to send a[i] as the first argument and not a.

Code:

---

cout>>b[i];

---

This should be cout<<b[i].

I change it to *a and it works but the function isn't running completely.
Can anyone tell me what do I need in order to store the same number become 1 and show in new array.
Example: i have original array is 223344
and it stores to new array 234
In my code it seems like store only first character of the array! Is my pointer setting wrong??????

Change this : search(a,b,size)
to this : search(a[i],b,size)

i figured out, it worked with *(a+i)
Thanks for helping:)

That is equivalent to a[i], which is more readable.

at first i tried the a[i] but it didn't work but I realized i had missed the [size] for point *b.For both case it works perfectly thanks a lot:)

Why do you use C-strings in the first place? Why aren't you using std::string?
