WebAug 21, 2024 · Prerequisite : sizeof operator in C. The sizeof for a struct is not always equal to the sum of sizeof of each individual member. This is because of the padding added by the compiler to avoid alignment issues. Padding is only added when a structure member is followed by a member with a larger size or at the end of the structure. WebVerified answer. biology.
