Struct padding in C is necessary to ensure alignment of structures during memory allocation. This alignment ensures that data can be accessed quickly and efficiently, as some processors require that certain types of variables start at a specific memory address. For example, some systems might require an integer to start on a 4-byte boundary or a float to start on a 4-byte boundary as well.

void main() { char far *farther,*farthest; printf("%d..%d",sizeof(farther),sizeof(farthest)); }
