Conditional or Ternary Operator (?:) in C
The conditional operator in C is kind of similar to the if-else statement as it follows the same algorithm as of if-else statement but the conditional operator takes less space and helps to write the if-else statements in the shortest way possible. It is also known as the ternary operator in C as it operates on three operands.. Syntax of Conditional/Ternary Operator in C
The ternary (conditional) operator in C
like dwn said, Performance was one of its benefits during the rise of complex processors, MSDN blog Non-classical processor behavior: How doing something can be faster than not doing it gives an example which clearly says the difference between ternary (conditional) operator and if/else statement. give the following code:
C Ternary Operator (With Examples)
Syntax of Ternary Operator. The syntax of ternary operator is : testCondition ? expression1 : expression 2; The testCondition is a boolean expression that results in either true or false.If the condition is . true - expression1 (before the colon) is executed; false - expression2 (after the colon) is executed; The ternary operator takes 3 operands (condition, expression1 and expression2).
Conditional Operator in C ( ?: ) with Example
The conditional operator in C is a conditional statement that returns the first value if the condition is true and returns another value if the condition is false. It is similar to the if-else statement. The if-else statement takes more than one line of the statements, but the conditional operator finishes the same task in a single statement.
Conditional Rules (GNU C Language Manual)
8.4.1 Rules for the Conditional Operator. The first operand, condition, should be a value that can be compared with zero—a number or a pointer.If it is true (nonzero), then the conditional expression computes iftrue and its value becomes the value of the conditional expression. Otherwise the conditional expression computes iffalse and its value becomes the value of the conditional expression.
Ternary conditional operator
In computer programming, the ternary conditional operator is a ternary operator that is part of the syntax for basic conditional expressions in several programming languages. ... In C++ there are conditional assignment situations where use of the if-else statement is impossible, ...
Assignment and Conditional Operators in C
Assignment and Conditional Operators in C. The assignment operator ( =) is used to assign a value to a variable. It has the following syntax: variable = expression; Where variable is the name of the variable to be assigned a value, and expression is the value to be assigned. Example: int x; x = 5; // Assigning the value 5 to variable x.
C Assignment Operators
The assignment operators in C can both transform and assign values in a single operation. C provides the following assignment operators: | =. In assignment, the type of the right-hand value is converted to the type of the left-hand value, and the value is stored in the left operand after the assignment has taken place.
Assignment operators
Assignment performs implicit conversion from the value of rhs to the type of lhs and then replaces the value in the object designated by lhs with the converted value of rhs . Assignment also returns the same value as what was stored in lhs (so that expressions such as a = b = c are possible). The value category of the assignment operator is non ...
Conditional Operator, Comma operator and sizeof() operator in C
The precedence of the conditional operator is quite lower than the arithmetic, logical and relational operators. But it is higher than the assignment and compound assignment operator. The associativity of conditional operator is from right to left (see Operator Precedence in C). Consider the following conditional expression:

One of the most elegant applications of these two principles is to declare a variable in a conditional." -- Stroustrup, "The C++ Programming Language." - Andy Thomas. ... assignment operator and conditional statements. 0. setting a variable in an if statement. 1. Make assignment within if-statement. 1.

Operator overloadability. A user-defined type can't overload the conditional operator. C# language specification. For more information, see the Conditional operator section of the C# language specification. Specifications for newer features are: Target-typed conditional expression; See also. Simplify conditional expression (style rule IDE0075)
C Operator Precedence
↑ Assignment operators' left operands must be unary (level-2 non-cast) expressions. This rule grammatically forbids some expressions that would be semantically invalid anyway. Many compilers ignore this rule and detect the invalidity semantically. ... In C++, the conditional operator has the same precedence as assignment operators, ...
Assignment and shorthand assignment operator in C
C supports a short variant of assignment operator called compound assignment or shorthand assignment. Shorthand assignment operator combines one of the arithmetic or bitwise operators with assignment operator. For example, consider following C statements. The above expression a = a + 2 is equivalent to a += 2.
c++
The operator precedence in the C/C++ language in not defined by a table or numbers, but by a grammar. Here is the grammar for conditional operator from C++0x draft chapter 5.16 Conditional operator [expr.cond]: conditional-expression: logical-or-expression logical-or-expression ? expression : assignment-expression
Assignment operators
for assignments to class type objects, the right operand could be an initializer list only when the assignment is defined by a user-defined assignment operator. removed user-defined assignment constraint. CWG 1538. C++11. E1 ={E2} was equivalent to E1 = T(E2) ( T is the type of E1 ), this introduced a C-style cast. it is equivalent to E1 = T{E2}
conditional statements
The reason is: Performance improvement (sometimes) Less code (always) Take an example: There is a method someMethod() and in an if condition you want to check whether the return value of the method is null. If not, you are going to use the return value again. If(null != someMethod()){. String s = someMethod();
Python Operators

All the operators within comparison operators have the same precedence order. ... It then uses a conditional assignment to determine the smaller of the two ...

C and many other languages have a conditional (AKA ternary) operator. This allows you to make very terse choices between two values based on the truth of a condition, which makes expressions, including assignments, very concise.
