C programming

In C, a function declaration provides information to the compiler about the name, return type, and parameters (if any) of a function.
A function declaration typically appears at the beginning of the program or in a header file.
Here's the syntax for a function declaration
return_type function_name(parameters);
Here are a few examples of function declarations:

// Function declaration with no parameters and returns void
void greetUser();
// Function declaration with two integer parameters and returns an int
int addNumbers(int a, int b);
// Function declaration with a char pointer parameter and returns void
void printMessage(char* message);
// Function declaration with no parameters and returns a double
double getRandomNumber();

These declarations provide information to the compiler, allowing the program to use these functions before their actual implementations.
It's important to ensure that the declarations match the actual function definitions in terms of return type, function name, and parameters.<\li>
