The value of an automatic variable that is declared but not initialized is indeterminate.
Some debug implementations will preset uninitialized variables to a known state, such as 0xcccccccc, or my favorite, 0xcacacaca, but that is just a hint that you are doing something very, very wrong if you ever encounter such a value.
In JavaScript undefined is a special value used when a variable has not had a value set to it, or has not been declared.
You can change a static variable by putting the static variable into a function that has operations that you intend to execute upon the variable. Example, you want to change the static variable to another value or make an addition of 2. Put the source code inside a function with the static variable declared locally within the function.Every time you call the function, the static variable value will change. Take note that the static variable retains the last value you declared it in your function call.A more terse answerLocal variables declared as static are changed as normal; they are special in that their values persist across function calls.
A variable declared as final can't be modified, once a value is assigned.
printf is declared in stdio.hFormat specifier for an integer value is %d.
If it is a class or instance variable, it gets the default value of false. If it is a local variable (inside a method), it doesn't have a value until you explicitly set one.
The local variable goes away and the value is lost.
A constant has only the exact value it's declared and can never be changed. A variable can have any number of values assigned. In programming, a variable can be given a value later in the code but can only be changed during runtime if its been declared as a pointer.
In JavaScript undefined is a special value used when a variable has not had a value set to it, or has not been declared.
The current status of the keyword variable in the program is dependent on its declaration and assignment within the code. If the variable has been declared and assigned a value, it is considered to be in use and holds that value until it is changed or the program ends. If the variable has not been declared or assigned a value, it is considered to be uninitialized and may cause errors if used in calculations or operations.
In programming, you can change the value of a variable, which is essentially assigning a new value to the variable. The type of data a variable can hold is typically fixed after it's declared, but the actual value can be updated as needed during the program's execution.

No. In COBOL, any variable must be declared with PIC statement.
A variable declared as final can't be modified, once a value is assigned.
Variables in PHP do not need to be declared like some languages (e.g. JavaScript). This is all that needs to be done to assign a variable: $variable = "Value";
printf is declared in stdio.hFormat specifier for an integer value is %d.
static variables are declared to define a variable as a constant., means if you declare a variable as static the variable becomes costant.syntaxstatic int a=100;this will make the value of a as 100 which is not to be changedWell, no; you think of 'const', which can be used together with static, but not necessarily.Yes you are right bro I was confused it should be const int a=100; then the variable will be a constant.
