c++ maps doesnt work

[zeroblank]

for(auto it = x.end();it != x.begin();it++)
{
if(location >= 4){
if((it->first) + D[k-(next(it,1))->second] > (next(it,1))->first +D[k-(it->second)]){
D[k-(it->second)] = 0;
}
else{
D[k-((next(it,1))->second)] = 0;
}

im using net beans and im getting the following errors

error: 'it' does not name a type

error: expected ';' before 'it'

error: 'it' was not declared in this scope

BUILD FAILED (exit value 2, total time: 4s)

Sounds like you don't compile with C++11 support.

What compiler does the netbeans environment use?

[dhayden]

Once you get the code compiled, you probably need to change this:
for(auto it = x.end();it != x.begin();it++)
to this
for(auto it = x.begin();it != x.end();it++)
Even then the code won't work since next() will return x.end() when you're processing the last item.
