Webb24 juni 2024 · Sizeof operator in C C Programming Server Side Programming The sizeof operator is the most common operator in C. It is a compile-time unary operator and used to compute the size of its operand. It returns the size of a variable. It can be applied to any data type, float type, pointer type variables.

WebbThe sizeof () is an operator in C and C++. It is an unary operator which assists a programmer in finding the size of the operand which is being used. The result of this operator is an integral type which is usually signified by size_t. This operator is usually used with data types which can be primitive data types like integer, float, pointer, etc. bzoj2750WebbThe function in C is not virtual, so the class doesn't need a vtable pointer, so it needs no more storage than A.
