use of conditional operator in c

The operands of predefined operators in C + + can only be basic data types, and in fact, for many user-defined types, similar operations are Required. For example:Class Complex{PublicComplex (double r=0.0,double i=0.0) {real=r;imag=i;}void Display ()

The following is a detailed summary of the description and function of various operational symbols in C #first, []square brackets ([]) are used for arrays, indexers, and properties, and also for pointers.1, the array type is a type followed by

If you want to get the largest of the two numbers, you can use the IF statement, for example: if (a>b) { max = A; } else{ max = b; } However, the C language provides a simpler method, called the conditional operator, with the syntax

Found a good article:Reproduced:This paper mainly summarizes the operator overloading and C + + operator overloading summary from C + +.What is operator overloadingOperator overloading is to give multiple meanings to existing operators, causing

In the previous introduction to semantic inspection, we have initially introduced the function checkbinaryexpression for the semantics of the two-tuple operator expression, and for the convenience of reading, here we give the figure 4.2.2 again. In

3 forms of an IF statement 1 an if (expression) statement. For example: if (x>y) cout The execution of this if statement is shown in the following figure. 2 if (expression) statement 1 Else Statement 2 For example: if (x>y)

An operator is a particular symbol or expression used to examine, modify, or merge variables. For example, with the sum operator + you can sum two digits (such as let i = 1 + 2); a slightly more complex example has logic and operator && (e.g. if

I. Switch-caseSwitch-case statements are mainly used in environments with multi-branch conditions where the use of if statements can be cumbersome and inefficient.switch (expression){Case Const EXPRESSION1:....Case Const
