    if you are speaking of a string.h file and you declare a string as String aString..then at school we used this..but i dont like it....

    Code:
    #include <lvp\string.h>
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
    String something;
    getline(cin, something);
    return 0;
    }
    that only works for some...i have never really implemented any strings in any of my code..i always think of them as array of characters like

    Code:
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
    	char* something = new char[100];
    	cin.getline(something, 100, '\n');
    	
    	delete [] something;
    	return 0;
    }

    Yes, getline for std::string's is implemented in <string>:
    Code:
    #include <iostream>
    #include <string>
    
    int main()
    {
      std::string s;
    
      if ( std::getline ( std::cin, s ) )
        std::cout<< s <<std::endl;
    }
    -Prelude
    My best code is written with the delete key.
