C programming - Passing arguments to a function

In C programming, you can pass arguments to a function by including them in the function call. The arguments are passed to the function using the function's parameter list, which specifies the data types and names of the arguments.

The syntax for passing arguments to a function in C is as follows:

function_name(argument1, argument2, ..., argumentN);

In this syntax, function_name is the name of the function, and argument1, argument2, ..., argumentN are the values to be passed as arguments to the function. If the function takes no arguments, you can omit the parentheses.

Here's an example of a function call that passes two integers to a function named add that returns the sum of the two integers:

int result = add(5, 7);

In this example, the function add takes two integer arguments, 5 and 7, and returns their sum, which is assigned to the variable result. When the add function is called with these arguments, it will perform the addition operation and return the result to the calling statement.

In the function definition, the parameters are declared with their corresponding data types, like this:

int add(int num1, int num2)
{
    int sum = num1 + num2;
    return sum;
}

In this example, the add function takes two integer parameters named num1 and num2. The parameters are used in the function body to perform the addition operation and calculate the sum, which is returned by the return statement.
