    Malloc & Calloc difference in terms of memory allocated

    Hi People,
    Please find my queries mention below.
    How is memory allocated by malloc?
    Is the memory allocated contiguous? Is so, What if the requested number of bytes are not available contigously?
    Is casting really required?? If u don't cast the pointer what will be the disadvantage?
    What is the difference between calloc and malloc in terms of memory allocation?
    I will be happy if some body could give me a diagramatic representation of the memory allocated by these two functions(calloc & malloc).

    If you give me the email address of your teacher, I'll save you the work and mail him the answers directly, ok? First, here's our Homework Policy, read it and then ask specific questions while trying to give the answer yourself. You didn't even take the time to formulate the questions yourself, you're simply copied the assignment .. how lazy is that ?

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
