DO you mean you want somebody to do your homework for you?

>This is not actually on the application side but more on the concept of VFP as a programming language
>
>Sequence Control
>1. Arithmetic Expresions
> - discuss the operator precedence and associativity rules, order of operand evaluation, short-circuit evaluation provided by the language
> - are there restrictions on operand evaluation side effects
> - does the language allow user-defined operator overloading?
> - what mode mixing is allowed in expressions?
> - type conversions being followed (if for ex. the language uses coercion, how?)
>
>2. Assignment Statements
> - Discuss the form of assignment statement/s provided
>
>3. Selection Statements
> - discuss the selection statement provided by VFP
> - What is the form and type of the expression that controls the selection?
> - Can a single statement, a sequence of statements, or a compound statement be selected?
> - How should the meaning of nested selectors be specified?
>
>4. Iterative Statements
> - Discuss the looping constructs provided by VFP
> - What is the type and scope of the loop variable?
> - What value does the loop variable have at loop termination?
> - Should it be legal for the loop variable or loop parameters to be changed in the loop, and if so, does the change affect loop control?
> - Should the loop parameters be evaluated only once, or once for every iteration?
>
>
>Data Control
>1. Different categories of subprograms and design issues for each
>2. Different parameter passing methods used by VFP
>3. Different kinds of type checking provided
>4. Design issues for subprograms
> 4.1 What parameter-passing method/s are used?
> 4.2 Are the types of actual parameters checked against the types of the formal parameters?
> 4.3 Are local variables statically or dynamically allocated?
> 4.4 If subprograms can be passed as parameters, what is the referencing environment of such subprogram?
> 4.5 If subprograms can be passed as parameters, are the types of parameters checked in calls to the passed subprograms?
> 4.6 Can subprogram definitions appear in other subprogram definitions?
> 4.7 Can subprograms be overloaded?
> 4.8 Can subprograms be generic?
> 4.9 Is either separate or independent compilation possible?
>
>5. How are referencing environments represented and used/accessed
>
>Thanks again!!!!
