Question

Which of the following is the correct header for a method definition named calcsum that accepts four int arguments and returns a double?

a) double calcsum(int a, int b, int c, int d);
b) calcsum(int a, int b, int c, int d): double;
c) int calcsum(a, b, c, d) double;
d) calcsum(double a, double b, double c, double d);

Answer 1

The correct method header for a function named calcsum that takes four integers and returns a double is 'double calcsum(int a, int b, int c, int d);'.

Step-by-step explanation:

The correct header for a method definition named calcsum that accepts four int arguments and returns a double is option a) double calcsum(int a, int b, int c, int d);

This header indicates that the method calcsum will return a double value and requires four integer parameters to operate. For clarity, the method definition specifies the type of each parameter immediately before the parameter name, which is the typical syntax used in languages like Java and C++.
