A storage class, outdated but still usable. Example:
size_t strlen (register char *p)
{
register char *s= p-1;
while (*++s);
return s-p;
}

No. Keywords are reserved and cannot be used as identifiers. However, C/C++ is case-sensitive. So although register is a reserved keyword, Register is not.
Faster execution of code.

A register specifier for a variable is a compiler hint that the variable is used often and should be kept in a CPU register. The compiler will treat the variable as automatic, but it will give it preference for staying in a register between sequence points.
In C/C++ when we declare a variable; e.g int var; for this variable (i.e. var) memory is being reserved in RAM (i.e out side processor). If we declare variable like that; register int var2; for this variable memory is being reserved in register of CPU (i.e. withing processor) But register variables are discouraged because processor has to work with registers..... Note: strictly speaking, storage class 'register' means: dear compiler, you might optimize this variable into register, as I won't ever request its address. But of course, it's up to you to decide.
Automatic, register, external, static
Hold down register key and cover thumb hole.
B# is the same as C. So low C would be all fingers down, low E key and the bottom thumb key (if your bass clarinet has a low C) Middle C is thumb and 1st 3 fingers Upper C is thumb, register key, all 6 fingers down plus the bottom C key (on either hand) High C is thumb and register key (Super C is thumb, register key and index fingers)
XRA A // Set A register to 0 LXI B,0909 // Load 9 into register B and 9 into register C // These are the numbers to multiply (adjust accordingly) LOOP: ADD B // Adds 9 to register A // If your assembler does not handle variables, // drop the LOOP: and refer to the line number // when you want to return to this point DCR C // decrease the value in register C by one JNZ LOOP // checks for Zero flag, if not found returns to LOOP // use the two bytes of your line number if you can not use LOOP HLT // Halt your program
