C Programming

I am not sure about the answer but think so,

Assembler: Its a program that converts a low level language into machine code, and there is a one-to-one correspondence between the source language statements and machine instructions

Macro- Assembler: It performs the same task as does the assembler but there is some times a one-to-many correspondence between the source language statements and machine instructions.

Please discuss further...

Asks the compiler to devote a processor register to this variable in order to speed the program's execution. The compiler may not comply and the variable looses it contents and identity when the function it which it is defined terminates.

A good variable name is one that is clear, related to the data it stores. Also, you should try to avoid confusions with other variables.

No. Nor with float or double. Use function dreml (or remainderl).

8*7*6*5*4*3*2*1 = 40320

yes,cursor implementation possible in priority queue.

when we write definition of a function i.e; body of a function above main() function, then the function prototype be omitted.

Which data type is the only one that can be used in calculations?

Yes, it does.

There are 6 types of Tokens in C which are as follows:-

1. Keyword

2. Identifier

3. Constants/Literals

4. Variable

5. Operator

6. Punctuator

Yes. However a control structure need not be complex. A control structure is simply a language mechanism that allows us to more easily express an otherwise procedural concept. For instance, consider the following procedural loop:

int x=0;

again:

if (!(x<10)) goto end;

// lots of statements...

++x;

goto again:

end:

This loop is much more easily expressed using a control structure:

for (int x=0; x<10; ++x) {

// lots of statements...

}

The resulting machine code will be exactly the same, so the level of complexity has not changed in any way. However, the latter is arguably much more readable because the loop conditions are all stated up front where they are easily seen and the body of the loop is contained within the loop statement itself.

The sizeof long int is platform-dependent, often 4 bytes or 8 bytes.

Generally,the cautery settings should be 60-80 cut and 60-80 coag. Set on blend.
