Question

The following C++ code:

int iBlocks[9][2];
class System{
  void setBlocks(){
    int iUCtr = 0;
    int iUYCtr = 105;
    while(1){
      int iUXCtr = 180;
      while(1){
        iBlocks[iUCtr] = 0;          //error happens here.
        iBlocks[iUCtr][0] = iUXCtr;
        iBlocks[iUCtr][1] = iUYCtr;
        iUCtr += 1;
        iUXCtr += 120;
        if(iUXCtr>420) break; 
      }
      iUYCtr += 120;
      if(iUYCtr>345) break;
    }
  }
  public:
    System(){
      setBlocks();
      cout << "Block settings set..." << endl;   
    }
};

MinGW g++ produces this error:

incompatible types in assignment of `int' to `int[2]'

The problem is at iBlocks[iUCtr] = 0;.

When I changed iBlocks to a pointer, it worked. Can someone explain to me what is going on under the hood?

Answer 1

The line iBlocks[iUCtr] = 0; is not required. Delete it.
