How to call the fun function in the C language?

In the C language, a function is called using the function name and a list of parameters. For calling the function fun, it should be done in the following format:

fun(参数列表);

The parameter list is determined based on the definition of the fun function. If the fun function has no parameters, the parameter list can be omitted, and the function can be called directly as fun();

For example, let’s say we have the following definition of a fun function:

#include <stdio.h>

void fun(int a, int b) {
    int result = a + b;
    printf("The result is: %d\n", result);
}

So, we can call the fun function in the following way:

fun(3, 5);

The code above calls the function “fun” and passes it two arguments, 3 and 5. The “fun” function will add these two arguments together and print out the result.

It is important to note that when calling a function, the number, type, and order of the arguments must match the function’s definition. Any mismatch in parameters could result in compile-time errors or runtime errors.
