do while with find_if
Hello,
Code:
std::map<int, bool > m_TacToAssignFlag;
auto itr = m_TacToAssignFlag.begin();
do
{
################
some more code here
################
bool bTacAssignCompl(false);
auto itr = std::find_if(m_TacToAssignFlag.begin(), m_TacToAssignFlag.end(), [bTacAssignCompl](const auto& elem) {return elem.second == bTacAssignCompl; }) ;
} while(itr != m_TacToAssignFlag.end());
In the above code, when the itr is m_TacToAssignFlag.end(), it still goes inside.
i used the find_if, to check , if any values in the map, is false..
Not sure what i am doing wrong
thanks a lot

Re: do while with find_if
You redefine the auto itr within the do/while loop.
Is it by design?

Re: do while with find_if
Code:
auto itr = std::find_if......
The scope of this itr only exists until the block closing }. It does not extend to the while clause. The itr used in the while clause is the same as that defined before the do loop.
You probably mean:
Code:
itr = std::find_if(
