An operator is a symbol that operates on a value or a variable. For example: + is an operator to perform addition. In this tutorial, you will learn about different C operators such as arithmetic, increment, assignment, relational, logical, etc. with the
Assignment Operators in C Bitwise Operators in C Misc Operators in C 1. Arithmetic Operators in C Operator Operator Name Description Example + Addition Adds two operands I = 40, J= 20I + J = 60 – Subtraction Subtracts second operand from the first I = 40, J= 20I – J = 20 * Multi...
It takes two operands, left shifts the bits of the first operand, the second operand decides the number of places to shift. In every left shift all bits are shifted to left adding a logical 0 at LSB. Example 4<<1 Before 1 left shift 00000100 After 1 left shift 00001000 → 8 So 4<...
Example: SQL IN Operator Example: IN Operator to Select Rows Based on Country Value TheINoperator can be used to choose rows where a specific value is present in the specified field. -- select rows with value 'USA' in the country columnSELECTfirst_name, countryFROMCustomersWHERE'USA'IN(coun...
In addition to the operators described inBasic Operators, Swift provides several advanced operators that perform more complex value manipulation. These include all of the bitwise and bit shifting operators you will be familiar with from C and Objective-C. ...
In the following example, the right-hand operand of the | operator is a method call, which is performed regardless of the value of the left-hand operand: C# Copy Run bool SecondOperand() { Console.WriteLine("Second operand is evaluated."); return true; } bool a = true | SecondOperand...
In this example, if no files match, theGet-ChildItemcommand returns nothing and assigns nothing to$textFiles, which is considered$falsein a boolean context. If one or moreFileInfoobjects are assigned to$textFiles, the conditional evaluates to$true. You can work with the value of$textFilesin...
However, this may not continue to be true in future versions of Oracle. To concatenate an expression that might be null, use the NVL function to explicitly convert the expression to a zero-length string. ExampleThis example creates a table with both CHAR and VARCHAR2 columns, inserts values ...
Type testing with pattern matching Theisoperator also tests an expression result against a pattern. The following example shows how to use adeclaration patternto check the run-time type of an expression: C# inti =23;objectiBoxed = i;int? jNullable =7;if(iBoxedisinta && jNullableisintb) {...
Create output sequences in a different format. For example, you can transform data from SQL rows or text files into XML. These transformations can be combined in various ways in the same query. Furthermore, the output sequence of one query can be used as the input sequence for a new quer...
