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. The minimum size for char is 8 bits, the minimum size for short and int is 16 bits, for long it is 32 bits and long long must contain at least 64 bits. The type int should be the integer type that the target processor is most efficiently working with.
