    Study Notes

    Scope of C Programming

    • Covers arrays, pointers, and memory allocation in C programming

    Basics of Pointers

    • Declaration: type *pointername; declares a pointer
    • Initialization: pointername = &amp;variablename; using &amp; operator
    • Changing/reading value at address: *pointername = value;

    Pointers with Arrays

    • Assigning array address to pointer: pointername = arrayname;
    • Using pointers: pointername can be used like an array name
