function declaration in c

A function declaration in C consists of the return type of the function, the name of the function, and the parameters it accepts. The syntax for a function declaration in C is as follows:

return_type function_name(parameter1_type parameter1, parameter2_type parameter2, ...);

Here is an example of a function declaration in C:

int addNumbers(int num1, int num2);

In this example, the return type is int, the function name is addNumbers, and it accepts two parameters of type int.

Note that a function declaration only specifies the function's signature (return type, name, and parameter types), and not its implementation. The actual code for the function's implementation would be written separately.
