small problem with strings

Expand Post »

Don't know what is wrong with this, it's giving me an error on the 'if (isalpha(string[i]))' line..I had it working earlier but then decided to put it into a function and it's not working now. It's giving the error "expected primary-expression before '[' token " for that line and the one below it. Any ideas on what i've left out? The program is fairly simple. Takes in a string and I just wanna look at any words in that string...so far I only output the characters but i'll transfer them into an array or something later for use. Cheers to anyone who solves this stupid error for me..

#include<iostream>

#include<cstring>



using namespace std;

void trim(char string[], int num);

int main()
{
    char string[20];
    cout << "Input a string: " ;
    gets(string);
    
    
    cout << "You input: " << string;    
    trim(string, 20);
    
}


void trim(string[], int num)
{
          
           for(int i=0; i<num; i++)
            {
              if (isalpha(string[i]))
               {
                   cout << string[i];
               }
            }
                 
           cin.get();
          
}

This should be:

void trim(char string[], int num)
