Vector

Vectors are same as dynamic arrays with the ability to resize itself automatically when an element is inserted or deleted, with their storage being handled automatically by the container.

Macro

A macro is a name given to a block of C statements as a pre-processor directive. Being a pre-processor, the block of code is communicated to the compiler before entering into the actual coding (main () function). A macro is defined with the preprocessor directive, #define.

Advantages of using macro

1. The speed of the execution of the program is the major advantage of using a macro.
2. It saves a lot of time that is spent by the compiler for invoking / calling the functions.
3. It reduces the length of the program.

    /* MACROS */
    #define vector(datatype)
    #define vector_init(vector)
    #define vector_expand(vector,expand)
    #define vector_push_at_nth_position(vector, value, position)
    #define vector_push_front(vector, value)
    #define vector_push_back(vector, value)
    #define vector_erase_from_nth_position(vector, position)
    #define vector_erase_front(vector)
    #define vector_erase_back(vector)
    #define vector_at(vector, index)
    #define vector_clear(vector)
    #define vector_for_each(vector, value)

Unit Testing

CUnit is a lightweight system for writing, administering, and running unit tests in C. It provides C programmers a basic testing functionality with a flexible variety of user interfaces.
