To solve this problem, we could define an array as dynamic (without specifying a size first) and then allocate memory for it using the ArrayResize function - passing a variable as a size is not difficult here.An alternative way to define a named constant is provided by enums, but is ...
In addition to the above types, a lot of constants are used in MT5. The easiest way to define these constants in this project, is to use the#definedirective of the preprocessor. Return codes of a trade server TRADE_RETCODE_...
The #define directive Figure 8. The program outputs the value of the constant, not the name When executed, the program will display exactly the number 354, and not the name. Note that the literal describing the number is not followed by a semicolon. When declaring constants using a ...
Let us first define the terms. The Display panel is a term we will use to describe a separate window custom display that has no drawing buffer. Such panel simply displays the required information using the chart objects embedded in the Terminal. The information can be displayed: numerically, a...
Select the step size from the wfo_stepSize list of predefined constants. The constant should be equal to the increment specified for the window size above. Disable the optimization for wfo_stepOffset and set its value to 0. When everything is set up, run the optimization and wait for its...
Declaration and definition of variables: Variable declaration is the step of creating them in a program. In this section, we look at how to declare and define variables, as well as how to specify their types. Context, scope, and lifetime of variables: ...
