To understand the difference between ++*p, *p++, and *++p. We need to understand the precedence and associativity of the operators. We will also see some C programs related to these operators. Evaluating postfix, prefix, and *: Precedence of postfix ++ is higher than prefix ++ and their associativity is also different. Associativity of postfix ++

In this blog post, we will learn pre-increment and post-increment in C/C++ with some example programs. We will also see what is the difference between pre-increment and post-increment operators and why in c++ pre-increment return lvalue and in C rvalue. What is a pre-increment operator? A pre-increment operator (++) is used to increment the

Standard C90 requires the elements of an initializer to appear in a fixed order, the same as the order of the elements in the array or structure being initialized. In ISO C99 you can give the elements in any order, specifying the array indices or structure field names they apply to, and GNU C allows

What are wild pointers in C? Uninitialized pointers are known as wild pointers. The behavior of uninitialized pointers is undefined because they point to some arbitrary memory location. Wild pointers may cause a program to crash or behave badly. Note: Generally, compilers warn about the wild pointer. int *ptr; //ptr is wild pointer Let see
