Number of bytes occupied by variables of type char short int in memory

Pictured , stay DEV C++ Direct programming in , adopt sizeof Keyword print out the number of bytes occupied by each variable type

You can see the corresponding relationship between the output result on the right and the code on the left , namely ：

char 1 byte ;short 2 byte ;int 4 byte ;long 4 byte ;float 4 byte ;double 8 byte ;

Later, I forgot that it can be passed directly in the code sizeof Keyword to view
