Question

#include <iostream>
#include <string.h>

using namespace std;

int main()
{
  char firstname[] = "Alfred";
  char middlename [] = "E";
char lastname[] = "Neuman";
  char fullname [80];
  int offset=0;

  strcpy(fullname,firstname);
  offset = strlen(firstname);
  strcpy(fullname+offset," ");
  offset +=1;
  strcpy(fullname+offset,middlename);
  offset += strlen(middlename);
  strcpy(fullname+offset," . ");
  offset +=2;
  strcpy(fullname+offset,lastame);

  cout << firstname << "." << middlename << "." << lastname << endl;
  cout << "Fullname:" << fullname << endl;

  return 0;
}

Why is offset needed in this and why is the off set added by 1 and 2, when we are dealing with text. I cannot seem to grasp strings and Arrays, anyone mind helping?

Answer 1

That’s because you’re using the wrong tools.

std::string firstname = "Alfred";
std::string middlename = "E";
std::string lastname = "Numan";
std::string fullname = firstname + " " + middlename + " . " + lastname;

The offset is used to track the current position of the string in the array so that you can strcpy the new argument into the right place.
