Dynamic allocation with scanf()

Question

My question is exactly the same as this one. That is, I\'m trying to use scanf() to receive a string of indeterminate length, and I want scanf() to dyn

Answer 1

I think, in real world, one need to have some maximum limit on length of user input.

Then you may read the whole line with something like getline(). See http://www.cplusplus.com/reference/iostream/istream/getline/

Note that, if you want multiple input from user, you don't need to have separate char arrays for each of them. You can have one big buffer, e.g. char buffer[2048], for using with getline(), and copy the contents to a suitably allocated (and named) variable, e.g. something like char * name = strdup( buffer ).
