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

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).

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).

if a=5,b=0;
it will like

when, has 1st var prefix
++a; add 1 extra after full line calculation if 1st var is post fix and next even pre, no need to add 1 extra

C = ++a + ++a + ++a;
Ans is 24 As consider to Turbo C 3.0
Because above expression is Register evaluation, thats why last updated value of a is used for all a in expression and last updated value is 8 ...(c=6+7+8 because of pre-increment.)
C=8+8+8=24

As the program execution in C is handled by stacks in the computer, when a variable is not assigned a value, the stack assigns a garbage value for it.

Why does ++i * ++i give 49 when i=5?

Ankush Batra

• Nov 1st, 2018

The ans is 49 only
bcoz i cant be 2 values(6, 7) at a time so, i should be 7 at last
thats why 7*7 = 49.

Sheetal Khatri

• Nov 13th, 2017

At first pre increment operator will increment the value of i, here first ++i will make the value 6 then 2nd ++i will make the value 7, now this value will replace the expression. so 7*7=49
Note that ++i (pre increment operator) will first increment and then evaluate.

You can use conditional operator like this,

String result = num % 2 == 0 ? "Even" : "Odd";

Chris

• Oct 28th, 2017

N%2 will give you 0 for even and 1 for odd. The string gives you the address of the start of the string. So for even it prints the string starting at the first character and for odd it starts at the 6th.

You can also use main() simply that means same as int main()..
int main() returns an exit value to compiler and works on most compilers.
And getch() as you mentioned has nothing to do with it. It gets character input on screen or else holds screen in other words
