minimize DFA c++ code has error

[suliman11]

hello

I have a problem In this code


//Function to minimize DFA
pair<int,vector<string tuple<int,int,bool>> > minimize_dfa(vector<dst) {
cout<<dfa.size()<<endl;
vector<int> grp(dfa.size()); /// Group number for states
vector<vector<int> > part(2, vector<int>()); /// Partition for groups

/// Initializing the groups
int part[0],.push_back(0);
for(int i=1; i<(int)grp.size(); i++) {
if(dfa[i].f==dfa[0].f) {
grp[i]=0;
part[0].push_back(i);
} else {
grp[i]=1;
part[1].push_back(i);
}
}

if(!part[1].size()) part.erase(part.end());


in the first line this message will appear
([Error] template argument 1 is invalid)

does any one know about this situation ?

Your function template minimize_dfa has an argument of vector<dst.

What is vector<dst ?? There's a missing > and an argument name.

Did you mean vector<dst> arg1 ??

There's also a typecast of grp.size() to an int. Anytime you cast in C++ it's an error unless you are interfacing with old-style C code. In this case vector::size returns a size_type, not an int.

You should be using iterators with vectors.
