#158559 - C standard Responding to: ???'s previous message |
Be it known that a C compiler always initializes all variables to zero or other values as per the C language standard.
But the language standard only cares about global variables - not unused memory or stack. Be it known that C51 compilers give the user access to the startup code to be able to change this behaviour. And some C51 compilers also allows variables to be placed in specific segments to inform the startup code to skip the initialization. But, for any C compiler/linker/RTL to be able to initialize all variables to zero, the environment must know about what memory the chip has. |
