assignment operator expression java

expression will be an error (such as floating point to do subscript); An expression that may lose information (such as assigning a long integer value to a short integer) warns but is legal;C does not specify whether Char is signed (but the printable character is guaranteed to be non-negative), and the conversion to int is related to the machine;if, while, the test part of for, "true" and "not 0" equivalent

The main introduction is operators, and mathematical functions as well as ternary operators: PackageTestbotoo; Public classTest1 { Public Static voidMain (string[] args) {intA = 122;SYSTEM.OUT.PRINTLN ("The result of calling operation is:" +operation (a));//call the method defined below }; Public Static intOperation (intv) { intXe = v + 1; intand = 10; returnXE; }}operator, basically similar to Python, except for the use of t

);2. printf formatted output function1) Direct output information when only one parameter is suppliedFor example:printf ("Hello world!");2) when outputting multiple parameters, you need to add the format control characterFor example:printf ("Hello world!%d", a);3. Format Control character%d displays signed integer data, such as Int,short type data;%u shows unsigned integer data, such as unsigned int, unsigned short data;%f display of real data, such as float type data;%c Displays character data,

Operator:-El expressions can perform various operations, where the commonly used operators are:650) this.width=650; "src=" Https://s5.51cto.com/oss/201710/22/05dea0d3757abbf849700caf01257614.png "title=" 12.png "alt=" 05dea0d3757abbf849700caf01257614.png "/>-In addition to the above operators, there is a very useful operator, empty, whose usage is the ${empty variable}, and the result is a Boolean value.

1 # include A = 60; B = 20; Expression 1, expression 2, expression 3, ------ expression N; The evaluation process is to first obtain the value of N expressions from left to right, and take the value of N expressions as the value of the whole expression. If there are Par

bits required by EOF is more than the number of digits provided by the character type value, it is truncated and prone to errors10. Try to use a compound assignment, the sizeof operator determines the type length of its operand, expressed in bytes, the operand can be an expression, or it can be a type name with parentheses on both sidesThe 11.

^ = Bitwise XOR or assignment operator c ^ = 2 equivalent to C = c ^ 2 | = Bitwise OR Assignment operators C | = 2 equivalent to C = C | 2 Conditional operator (?:)The conditional operator is also known as the ternary
