C++11 range-based for loops without loop variable

Question

In C++ I need to iterate a certain number of times, but I don\'t need an iteration variable. For example:

for( int x=0; x<10; ++x ) {
    /* code goes her         


        

Answer 1

this works in GCC and clang and any compiler that supports the gnu attributes:

for( [[gnu::unused]] auto x : boost::irange(0,10) ) {

and should compile in any c++11 compiler but may not suppress the warning if the compiler doesn't recognise the gnu attributes.
