conversion possible between the two types. Another possiblity is that they are declared in different declarations: Var A1 : Array[1..10] Of Integer; A2 : Array[1..10] Of Integer; Begin A1:=A2; { This statement also gives this error. It is due to the strict type checking of Pascal } End. Error: Type mismatch between "arg1" and "arg2" The types are not equal. Error: Type identifier expected The identifier is not a type, or you forgot to supply a type identifier. Error: Variable identifier expected This happens when you pass a constant to a routine (such as Inc var or Dec) when it expects a variable. You can only pass variables as arguments to these functions. Error: Integer expression expected, but got "arg1" The compiler expects an expression of type integer, but gets a different type. Error: Boolean expression expected, but got "arg1" The expression must be a boolean type. It should be return True or False. Error: Ordinal expression expected The expression must be of ordinal type, i.e., maximum a Longint. This happens, for instance, when you specify a second argument to Inc or Dec that doesn't evaluate to an ordinal value. Error: pointer type expected, but got "arg1" The variable or expression isn't of the type pointer. This happens when you pass a variable that isn't a pointer to New or Dispose. Error: class type expected, but got "arg1" The variable or expression isn't of the type class. This happens typically when The parent class in a class declaration isn't a class. An excep
this code. The TPC is giving me a type mismatch error in the first function call in the sqr procedure. I'll paste what the compiler is giving me.
