Question

Functions can directly return at most a single data type value to their calling functions. This value is the value of the expression in the return statement. True False

Answer 1

Functions in programming languages can return only a single value, determined by the expression in the return statement. The return type of the function determines the type of the value that can be returned.

Step-by-step explanation:

True. Functions in programming languages can return only a single value. This value is determined by the expression in the return statement of the function. The return type of the function determines the type of the value that can be returned. For example, in Python, a function can return an integer, a string, a boolean, or any other valid data type.

For instance, consider a function that calculates the square of a number:

def square(number):
return number * number

result = square(5)
print(result) # Output: 25

In this example, the return statement returns the result of the multiplication operation as an integer, which is then stored in the 'result' variable and printed.
