    Code:
     int a=3;
     float length=0.34;

    thought it was the same as java.

    Code:
      float number = 12.34f;
      double number2 = 12.3456;
      int number3 = 12;
      char name[] = "Hello";
      bool loop(true);

    Never seen a bool declared like that ever.
    Just to be sure use this.

    Code:
     bool loop=true;

    these things should be included in the first lesson!
    please leave the name of the college and the name of your teacher so others dont make the same misstake!

    All types have a constructor, even built in types. So you can use the initialization value as a constructor argument:
    Code:
    int a(10);
    bool loop(true);
    and the functionality is equivalent to
    Code:
    int a = 10;
    bool loop = true;
    :-)

    You can declare a string two ways :
    Code:
      string name = "john";
      string name2("john");
    by the same token I thought you could declare bool :
    Code:
      bool x=true;
      bool y(true);
    Works fine on my computer anyway
