Declaring a variable means describing its type to the compiler but not allocating any space for it. Defining a variable means declaring it and also allocating space to hold the variable. You can also initialize a variable at the time it is defined.

Yes the answer will be 225/15*15. As / and * has the same precedednce and associativity is from left to right so it will give 225(225/15*15 => 15*15 => 225).

In algebra * has higher precedence than /, but in C they have the same precedence, and are left-associative, meaning the operations are performed left to right.So 225 / 15 * 15 gives (225/15)*15 or 22...

If u want to initialize an array u will have to initialize it where it is declared. u cant initialze it later.so char arr[6][6]={"rotor","motor","peter","mater","water"};  is the correct way.

Program memory:where place your variable,you can read and write values

data memory:where tee application is stored some chips allows part of the program memory to be modified in block

The usage of static with a function or variable restricts their scope.Is this behaviour memory related?

jbode

 Profile Answers by jbode Questions by jbode

• Jun 5th, 2019

The static keyword does not affect where or how a function is stored in memory. It only affects whether the function *name* is visible to code outside of the current translation unit (source file).

Harsha

• Mar 27th, 2019

You have to specify where you are going to place it. You can do this in the linker file(.lsl or .ld file). If you place it in the .text section, it goes into the Flash, else by default a static function is placed in the RAM(.data).
