Here’s a simple Python function called hello
that takes a person's name as a string and returns the greeting:
def hello(name):
return f"hello {name}"
When you call hello("Alice")
, it will return the string "hello Alice"
.
A function. You can have a function that returns but doesn't return a value with it.
called function
In most computer languages, a procedure that returns a value is called a function and a procedure that does not return a value is called a subroutine or subprogram. Usually the languages treat the passing of arguments/parameters differently between functions and subroutines. The C language does not distinguish between them. A subroutine that does not return a value is define as a "void" function indicating that no return value is used or available.
The function already exists in PHP and is even called max(); Otherwise use: function max ($one, $two) { return $one > $two ? $one : $two; }
The statement that causes a function to end and sends a value back to the calling part of the program is the return statement. When a return statement is executed, it terminates the function and can optionally pass a value back to the caller. If no value is specified, the function returns None in Python or equivalent in other languages. This allows the caller to receive the result of the function's computation.

called function
When a function gets called, the processor first stores the address of the calling function in a structure called activisation structure and jumps to the called function. Then it allocates the memory for the local variables and initializes them. Then it does the processing in that function. After that it deallocates the memory allocated for the local variables and returns to the calling function.

Function Keys
The PV function is a financial function. It is used to return the present value of an investment based on an interest rate and a constant payment schedule. The syntax is a follows: PV( rate, number_payments, payment, [FV], [Type] ) Rate is the interest rate for the investment. Number_payments is the number of payments for the annuity. Payment is the amount of the payment made each period. If it is omitted, you have to enter a FV value. FV is optional. It is the future value of the payments. If it is omitted, it is assumed to be 0. Type is optional. It indicates when the payments are due. Type can be one of the following values: 0 for when payments are due at the end of the period, which is the default. 1 for when payments are due at the start of the period. If the Type parameter is left out, the PV function sets the Type value to 0.
int counter() { // This function returns how many times it has been called // Since this is a static variable, this line will only be called the first time the function is called static int count = 0; return(++count); }
That's up to you, except for the main function, the name of which has to be main.Or, if you want to know how to call a function, it's simply by its name, followed by an argument list, eg:int main (void){puts ("I have just called function puts");return 0;}
Excel has a category called Logical Functions. The IF function is the one of those that most people use and associate with returning True or False values. Other functions also return True or False values. There is a TRUE function and a FALSE function. The OR function and the AND function can be used to return True or False values too. The NOT function can reverse a True or False value, so it also returns True or False.
The function that displays the lowest value in a range is called the "MIN" function. In spreadsheet applications like Microsoft Excel or Google Sheets, you can use it by entering =MIN(range) where "range" refers to the set of cells you want to analyze. This function returns the smallest numerical value from the specified range.
In most computer languages, a procedure that returns a value is called a function and a procedure that does not return a value is called a subroutine or subprogram. Usually the languages treat the passing of arguments/parameters differently between functions and subroutines. The C language does not distinguish between them. A subroutine that does not return a value is define as a "void" function indicating that no return value is used or available.
Both a function and a subroutine are examples of out-of-line execution calls to code. The main difference is that a function call can be part of an expression and returns a value, whereas the subroutine can be called standalone and does not return a value.
