Left align, left alignment, or left justify is text, pictures, tables, graphics, or page formatting that aligns text along the left side (margin) of a document, page, or containing element. This text has a ragged right edge because it is left-aligned instead of being right aligned.

Keeping this in consideration, what does 4 byte aligned mean?

For instance, in a 32-bit architecture, the data may be aligned if the data is stored in four consecutive bytes and the first byte lies on a 4-byte boundary. Data alignment is the aligning of elements according to their natural alignment. Why is memory alignment necessary? The CPU can operate on an aligned word of memory atomically, meaning that no other instruction can interrupt that operation. This is critical to the correct operation of many lock-free data structures and other concurrency paradigms.

What is C alignment?

One of the low-level features of C is the ability to specify the precise alignment of objects in memory to take maximum advantage of the hardware architecture. CPUs read and write memory more efficiently when they store data at an address that's a multiple of the data size.
