Type pVoltage : POINTER TO INT; End_Type Address Operator (@) You can assign the address of a variable using the address operator, commercial at (@) character. For example: Var V1, V2 : INT; pV : Pointer to INT; End_Var (* Get the address of V2 *) pV := @V2; ...

POINTER: references the address of a variable. A pointer contains an address instead of a value. When you supply a value to a formal parameter of the parameter type POINTER, you specify an address as the actual parameter. In STEP 7, you can specify a pointer in the pointer format or sim...
A pointer variable stores the address of a variable (that must be non-pointer type), but when we need to store the address of any pointer variable, we need a special type of pointer known as "pointer to pointer" or "double pointer".Thus, double pointer (pointer to pointer) is a ...
type *var-name; 1. Here, type is the pointer's base type; it must be a valid C data type and var-name is the name of the pointer variable. The asterisk * used to declare a pointer is the same asterisk used for multiplication. However, in this statement the asterisk is being used...

Statement and Attribute: Specifies that an object or a procedure is a pointer (a dynamic variable). A pointer does not contain data, but points to a scalar or array variable where data is stored. A pointer has no initial storage set aside for it; memory
.orElse("UNKNOWN"); Unfortunately, this code doesn't compile. Why? The variable computer is of typeOptional<Computer>, so it is perfectly correct to call themapmethod. However,getSoundcard()returns an object of typeOptional<Soundcard>. This means the result of the map operation is an object...
