ESP, EBP pointer in stack manipulation
I often confused with the list of data that is pused into the stack frame when function is invoked.
As for as i know, return address, local variables, parameters are pushed into stack frame. But what i would like to know is the concrete details. Could someone provide ?

My guess is, that this is a homework type question so you need to cosult more info for some details.
Pointers to it use are:
SP (ESP for 32bit, RSP for 64bit) is the stackpointer ie. it points to the top of the stack.
- PUSH AX ==> in microcode = STACK[++SP]=AX
BP is used as a frame pointer most common use at procedure entry:
PUSH BP
MOV SP,BP
Now BP can be used to access parameters & local variables.
For more details consult your compilers manual. It's use is language/compiler specific.

C
C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
