Doubt in a concept;

[vageesha (Vageesha Umesh Chandra)]

Sir, I had a doubt.
If for example we take an unordered map as
unordered_map <int,int>m
and then we do something like m[d]++ .
Here if we will check m.find(d)!=m.end() then it will come.
now if we subtract 1 and now we have m[d]=0 right. So, if we will check for m.find(d) will it be equal to m.end() or it is still present but its value is 0???

find will check whether the key (d) is present or not , it has nothing to do with the value correponding to that key
