WebSize of Data Types in C++. The size of data types is dependent on the compiler or you can say that the system architecture i.e. 32-bit compiler or 64-bit compiler. The size of data type int is 2 byte in 32-bit architecture or 4 bytes in 64-bit architecture. Another factor on which the size of data type depends is the compiler on which you ... Websize () of string gives the number of elements in the string whereas sizeof () function on a string gives three extra bits. strlen () of a character array gives the number of elements + 1 (because of null char delimiter) and keep in mind size of char is 1 byte. sizeof () on a char array gives the size assigned to the array.
