Astring variable, fullname, contains a name in one of two formats: last name, first name (comma followed by a blank), orfirst name last name (single blank)extract the first name into the string variable firstname and the last name into the string variable lastname. assume the variables have been declared and fullname already initialized. you may also declare any other necessary variables.

#include <iostream>

using namespace std;

int main()

{

   char fullname[30];

   string fname="",lname="";

   int i,j;

   cout<<"Enter fullname\n";

   cin.getline(fullname,30); //so that blank can be read

   for(i=0;fullname[i]!=' ';i++)

       fname+=fullname[i];   //fistname will be saved

      cout<<"\n";

   for(j=i;fullname[j]!='\0';j++)

       lname+=fullname[j];    //lastname will be saved

   cout<<"\nFirstname : "<<fname<<"\nLastname : "<<lname;

   return 0;

}

OUTPUT :

Explanation:

cin.getline() should be used instead of cin in case of strings so that space can be read otherwise after blank string will be ignored.
