space in strcat

howdy,
when using the strcat function is it possible to place a space or defined character between the strings being joined

Code:

---

#include <iostream>
#include <string>
int main()
{
  char* fn;
  char* ln;

          cout<<"First Name?: ";
          cin>>fn;
          cout<<"Last Name?: ";
          cin>>ln;
         
  cout<<"Name: "<< (strcat(fn, ln))<<endl;
return 0;
}

---

for example place an asterisk between the first and last names.

btw - this code works but gets a run time error "aborted"on g++, no idea why??

thanks
M.R.

you allocate no storage space of any kind for the data!

not really without two calls,

use sprintf()


int sprintf( char *buffer, const char *format [, argument] ... )

char fn[20];
char ln[30];

or use the 'new' operator to allocate space for your data.

you could utilize the arrays and find out how long your string is and write a space over the null character and a null character in the array char. Then do your strcat()...

or do two calls as no_one mentioned

strcat(fn, ' ');
strcat(fn,ln);

or even easier

cout << "enter your first and last name: "
cin.getline(namearray,40,'\n');
