What are some of the best time-saving tips for C language?
That sounds really useful. Can you give me an example of a macro that would be helpful in C programming?
Sure. Here's an example of a macro that can save you time when working with arrays:

#define ARRAY_SIZE(arr) (sizeof(arr) / sizeof((arr)[0]))

You can use this macro to quickly determine the number of elements in an array, without needing to manually count them. Just call ARRAY_SIZE(arr) with your array as the argument, and the macro will return the size of the array.
