Does the range-based 'for' loop deprecate many simple algorithms?

Question

Algorithm solution:

std::generate(numbers.begin(), numbers.end(), rand); 

Range-based for-loop solution:

for (int& x : numbers) x = rand(); 

Why would I want to use the more verbose std::generate over range-based for-loops in C++11?

Answer 1

The first version

std::generate(numbers.begin(), numbers.end(), rand); 

tells us that you want to generate a sequence of values.

In the second version the reader will have to figure that out himself.

Saving on typing is usually suboptimal, as it is most often lost in reading time. Most code is read a lot more than it is typed.
