C++ Remove new line from multiline string

Question

Whats the most efficient way of removing a \'newline\' from a std::string?

Answer 1

If its anywhere in the string than you can't do better than O(n).

And the only way is to search for '\n' in the string and erase it.

for(int i=0;i

For more newlines than:

int n=0;
for(int i=0;i

It erases all the newlines once.
