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
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 ()
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
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
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
"operator"at the time of the operation, if the closing parenthesis we know what to do first, then if there is no parentheses, arithmetic operators, relational operators, logical operators, bitwise operators, assignment operators, + + 、--operators,
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
The operations object of a predefined operator in C + + can only be a basic data type, and in fact, a similar operation is required for many user-defined types. For example:Class Complex{PublicComplex (double r=0.0,double i=0.0) {real=r;imag=i;}void
