Some common relational operators include < (less than), > (greater than), <= (less than or equal to), >= (greater than or equal to), == (equal to), and != (not equal to). The purpose of relational operators is to compare values and determine their relationship with one another, such as whether one value is greater than another or equal to another.
If a relational operator is used with non-comparable data types, such as trying to compare a string with a number, an error will occur. Relational operators are typically used in conditional statements, such as if-else statements or while loops, to evaluate a condition and determine the outcome of the program based on the condition's relationship with other values.
Yes, relational operators can be used with Boolean values, with true being considered greater than false. The == operator compares two values for equality, but performs type coercion if the values are not the same data type. The === operator, on the other hand, compares two values for both equality and data type and does not perform type coercion.
The expression '10 >= 10' is true, as 10 is equal to 10. The expression '5 < 3' is false, as 5 is not less than 3.

How are parameters passed to subprograms? What is the role of the main program in passing data to and from subprograms?
What is the difference between passing data by reference and passing data by value? What is the syntax for calling a procedure?

 

Passing data out of subprograms is the process of returning processed data from a subprogram (function) to the main program. It is done by using the function's return statement. Passing data in subprograms is the process of transferring data from the main program to a subprogram (procedure) for further processing. It is done by passing variables as arguments to the subprogram.
A function is a subprogram that performs a specific task and returns a value. It is defined using the 'function' keyword followed by the function name, its parameter list and the data type of its return value. A procedure is a subprogram that performs a specific task without returning a value. It is defined using the 'procedure' keyword followed by the procedure name and its parameter list.
The main program is responsible for calling the subprogram and passing data as arguments. It receives the processed data from the subprogram and stores it for further processing. Parameters are passed to subprograms by reference or by value. By reference means that the address of the variable is passed to the subprogram, while by value means that the actual value of the variable is passed.
To call a procedure, use the procedure name followed by its parameter list enclosed in parentheses. For example: procedure_name(argument1, argument2, ...) Passing data by reference means that the address of the variable is passed to the subprogram, while passing data by value means that the actual value of the variable is passed. In passing by reference, changes made to the parameter variable within the subprogram are reflected in the original variable in the main program.

The return statement is used to return a value from a function to the main program. The value can be a constant, variable or expression. For example: 'return variable;' To call a function, use the function name followed by its parameter list enclosed in parentheses. For example: function_name(argument1, argument2, ...)
Multiple values can be returned from a function by using arrays, structures or pointers. When no return statement is used in a function, it returns a default value based on its data type. For example, a function with a data type of 'int' returns 0 by default.
Recursion is the process of calling a subprogram (function or procedure) within itself. It relates to passing data to and from subprograms because each recursive call passes data to the subsequent call and receives data from the previous call. Local variables are variables declared within a subprogram and can only be accessed within that subprogram. Global variables are variables declared outside of any subprogram and can be accessed by any subprogram within the program. They are used in subprograms to store and manipulate data.

A value parameter is a parameter that passes a copy of the data to the subprogram, and any changes made to the parameter inside the subprogram are not reflected outside the subprogram. The types of parameters in subprograms include value parameters, reference parameters, and output parameters.
An output parameter is a parameter that returns a value from the subprogram to the caller, and any changes to the parameter inside the subprogram are reflected outside the subprogram. A reference parameter is a parameter that passes a reference to the data to the subprogram, and any changes made to the parameter inside the subprogram are reflected outside the subprogram.
A return value is a value that is returned from a subprogram to the caller, and can be used in expressions or assigned to variables. A global variable is a variable that is declared outside of any subprogram, and can be accessed by any subprogram in the program.
