c++ - How to reverse iterate vector with iterator? -


for example:

for(int i=0;i<v.size();i++){  }

is normal order,

for(int i=v.size()-1;i>=0;i--){  }

is reversed order,

how reverse version of iterator?

for(vector<int>::iterator it=v.begin();it!=v.end();++it){  }

also there reverse version of code style?

for(int : v){  }

use reverse iterator:

for(auto = v.rbegin(); != v.rend(); ++it){/*...*/}

there no built in way range based for in reverse, use boost::adaptors::reversed:

for(auto& : boost::adaptors::reversde(v)){/*...*/}
