i was trying to run my code but error come out

class Board:public State(){

private:
    vector<int>blocks;

public:
    void generateIntlState() {
        int bIndex = 0;
        intializeBlocks();

    for(int r = 0; r < BOARDSIZE; r++){
        for(int c = 0; c < BOARDSIZE; c++){
            setVal(r,c blocks[bIndex]);
            bIndex ++;
        }
    }
    pushBlockDown();
    }



    void intializeBlocks(){
    int zeroCount = 1;

    for (int i = 1; i < 9; i ++){
        blocks.push_back(i);
        if(zeroCount<=3){
            blocks.push_back(0);
            }
            zeroCount++;
        }
    for( int i = 8; i > 0; i--){
        int num=rand()% i;
        int temp = blocks[i];
        blocks[i] = blocks[num];
        blocks[num] = temp;
        }
}

    void findActHeuristic(priority_queue<Action>&actions, Goal g){
    Action a;
    vector<Action>actions_vec;
    vector<State> states;
    int h = 0;

    for(int r = 0; r < BOARDSIZE; r++){
        for(int c = 0; c < BOARDSIZE; c++){
          if((r != c)&&(isFull(r))&&(isEmptu(c))){
            a.setAction(r,c);
            actions_vec.push_back(a);
            }
        }
    }
    for(int i = 0; i <actions_vec.size(); i++){
        State newState = nextState(actions_vec[i]);
        states.push_back(newState);
        if(newState.getVal(g.getRow(),g.getColumn()) == g.getVal()){
            h = 100;
        }else if(newState.isOnTop(g.getVal())&&(newState.isColumnEmpty(g.getColumn()))){
            h = 95;
        }else if(newState.isOnTop(g.getVal())&&(newState.isBlockEmpty(g.getColumn()))){
            h = 85;
        }else if(newState.isBlockEmpty(g.getRow(),g.getColumn())){
            h = 65;
        }else if(newState.isColumnEmpty(g.getColumn()))&&(getRowPos(g.getVal()) > g.getRow()){
            h = 55;
        }else if(newState.isColumnEmpty(g.getColumn())){
            h = 50;
        }else if(newState.isOnTop(ggetVal())){
            h = 40;
        }else if(newState.isColumnFull(g.getColumn())){
            h = 1;
        }else{
            h = 5;
        }
        actions_vec[i].setHeuristic(h);
        actions.push(actions_vec[i]);
    }


    template<typename T>void priority_queueQ(priority_queue<T>q){
    while(!q.empty()){
        q.top().printGoal();
        q.pop();
        }
        cout << endl;
        }
    }
};

And if i delete () and more error come out

What I have tried:

This it's the error:

error: expected class-name before '(' token|
error: expected '{' before '(' token|
error: expected unqualified-id before ')' token|

Four almost-identical questions in two days. I think you need to go back and re-read your class notes.

And just for the record, you are nowhere near being able to "run" your program, it won't even compile.

Solution 1

Ok let me see where do I start.

C++

class Board:public State(){

should be

C++

class Board:public State{

For loop

C++

setVal(r, c blocks[bIndex]);

should be either

C++

setVal(r, c, blocks[bIndex]);

or remove "c" token.

I assume that the majority of functions declared in the State class? Because if they're not, this is yet another problem.

And I am assuming that you have following line visible to your code:

C++

#include <vector>
#include <queue>

using namespace std;

Spend a few weeks reading beginners c++ book to get an idea about strict syntax rules. At current junction you are obviously in over your head

How many times are you going to ask the same question until you learn to fix this yourself?
Why my code not working ?[^]
Why my code not working ?[^]
Can you help me to fix my code ?[^]
If you had done what you were told to the first time you posted this (and the second, and the third), you could have solved this yesterday.

You are not going to learn to fix compiler errors by desperately hoping others will fix them for you ... and you are going to have many, many more of them in future - we all do - so learnign to fix them yourself is kinda important if you want to advance beyond one line of correctly-compiling code per week.
