1) Precedence of prefix ++ and * is same. Associativity of both is right to left. 2) Precedence of postfix ++ is higher than both * and prefix ++. Associativity of postfix ++ is left to right. The expression ++*p has two operators of same precedence, so compiler looks… Read More »Difference between ++*p, *p++ and *++p?

Heap Area:It is used for the objects allocated dynamically (Using malloc() and calloc()). Stack Area:It is used to store local variables and arguments of a method. This stays in memory only till the termination of that particular method.

Let’s take an example to understand it. Suppose double a=1.5; int b=10 and we want to calculate a+b By type demotion, float type a will convert to int. Therefore a=1 and a+b=1+10=11 but we know that correct answer is 11.5 which will only get by… Read More »Why does “type demotion” does not exist instead of “type promotion”? Also, it would consume less space resource than by doing it from type promotion.?

These are some old concepts used in 16 bit Intel architectures in the days of MS DOS, not much useful anymore. Near pointer is used to store 16 bit addresses means within current segment on a 16 bit machine. The limitation is that we can only… Read More »What is the difference between near, far and huge pointers?

Semi-colon is needed by the compiler and as the name suggests Preprocessors are programs that process our source code before compilation. Therefore the semi-colon is not required.

Modifier is a prefix to the basic data type which is used to indicate the modification for storage space allocation to a variable. Example– In 32-bit processor storage space for the int data type is 4.When we use it with modifier the storage space change as… Read More »Describe the modifier in C?

Yes, it is working without any error. Some programmers like to use this to organize the code. But the main purpose of curly brackets is to group several lines of codes.

Incorrect operator is ‘<>’.This is the format correct when writing conditional statements, but it is not a correct operation to indicate not equal in C programming and it gives compilation error as follows. Code Error

C support only 2 loops: Entry Control: This loop is categorized in 2 part a. while loop b. for loop Exit control: In this category, there is one type of loop known as a. do while loop.

main is necessary for executing the code. Code is void main() { }
