One byte; ;

The memory size occupied by double is 8.

One byte; ;

The memory size occupied by char is 1.

You can test it with sizeof.

Extended data:

C language is a general computer programming language, which is widely used in the bottom development. The design goal of C language is to provide a programming language that can compile and process low-level memory in a simple way, generate a small amount of machine code and run without any support of running environment.

Although C language provides many low-level processing functions, it still maintains good cross-platform characteristics. C language programs written in standard specifications can be compiled on many computer platforms, even including some embedded processors (single chip microcomputer or MCU) and supercomputers.
