Conditional Operator in C ProgrammingOverviewIn C, the conditional operator ?: is a shorthand for an if-else statement. It is called the ternary operator because it operates on three expressions:Exp1 ? Exp2 : Exp3;Exp1: The condition to evaluate. Exp2: The result if Exp1 is true (non...
In the C and C++ programming language, sizeof() operator is used to get the size of a data type, size of an expression/variable. It accepts a parameter (either data type or expression) and returns the size of the operator.sizeof() operands can be:...
Ternary operators in C (?:), also known as conditional operators in C, are a short way to write conditional expressions that facilitate decision-making in code. They can replace if-statements but should be used with caution. Shivani Goyal 20 mins read Table of content: What Is Conditional...
C provides a compile-time unary operator calledsizeofthat can be used to compute the size of any object. Thesizeofoperator can be used in two forms. First, to get size of an object that can be a variable or array or structure. Second, to get size of a type name that can be the ...
Bitwise Operator in CThe bitwise operators are the operators used to perform the operations on the data at the bit-level. When we perform the bitwise operations, then it is also known as bit-level programming. It consists of two digits, either 0 or 1. It is mainly used in numerical ...
Operator Precedence in C Operator precedencedetermines which operator is evaluated first when an expression has more than one operators. For example 100-2*30 would yield 40, because it is evaluated as 100 – (2*30) and not (100-2)*30. The reason is that multiplication * has higher precede...
to determine the storage requirements of an int variable on ourcomputer. The operator sizeof can also be used on any variable as shown in the example below. int kk; printf(“sizeof(kk) = %d bytes”, sizeof(kk); The sizeof operator precedes either a variable name OR a datatype name....
C程序设计语言中提供了两个特有的运算符 ,即自增运算符 ( ++ )和自减运算符 ( - - ) ,用于对变量加 1、减 1正确理解并使用这两个运算符对于编写C程序是很重要的 。 2. Auto-increment、auto-decrementoperatoris used flexibly in C programming language. ...

Const may not have been part of original C, but the macro pre-processor goes way back. One place where I've seen it used is in an array package that used macros for bound-checked array accesses. The syntax for a checked reference was something like aref(arrayname, type, index), where...
