s.erase()

[Jason Heyes]

I have a std::string 's' and I write:

s.erase();

Does this make the string empty?

Thanks.

Depends on how you define 'empty'.

s.empty()

Try this to check yourself:

<code>

#include <string>
#include <iostream>

int main()
{
std::string s("Hello World");
s.erase();
std::cout << "s is " << (s.empty() ? "empty" : "not empty") << std::endl;
return 0;
}

</code>

I would prefer a direct answer.

Can't be that hard to figure out...


$ ./strempty
s is empty

You have a big problem either with your brain or with your computer if
compiling and executing a small test program destroys a significant amount
of your brain cells.
