please i need help. i need to create "Title"(it is a data member of a class) which is a string of variable size and it is dynamically created and defaults to an empty string.
In a class i created a member function setTitle() that prompts the user to enter a title,
its as the following:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
char *title="";//the array that is supposed to hold the input
cout << "Title: ";
cin >> title;//take the input
Title = newchar[strlen(title)+1];//create a char array for Title of size same as title with an additional for '\0'
assert(Title != 0);
strcpy(Title, title);//copying content of title to Title
cout << Title;
when i run this it give me no error,but when i put a value for Title it stops responding,
please i need help as soon as possible. This should read whole input even with spaces between words
Ofcourse it does. I mean don't pointers to characters have as much space as u input in them.
Doesnt their space expand depending on the input?
No, everything only has as much space as you allocated, and nothing magically adjusts depending on what you input into it. std::string hides all the dirty work for you by resizing itself as more and more input is available.
