General way of passing arguments to functions in c

I would like to ask a certain question in regards to C programming.

I have a function which takes a parameter 'x'.

The function is supposed to do actions based up on the x.

So i have a source file where i have this function

file.c

   y=random number

And i want to call this function to do actions.

function(x);

And now x must be equal to y

Well the problem here is i want to pass y value to x.

Is there any regular way of doing so?

If there is any please help me understand and also to make it clearer.

Regards Rookie

Within your function(x), x will be equal to whatever value is pass to the function. If you use function(y), then within the function, x will be equal to y. If you use function(7), then x would be equal to 7. Functions are usually defined with a return type and a parameter type.

void function( int x)

would define function that takes a type of integer and returns nothing.

int function( int x)

would define a function that takes a integer value and returns a integer value.

double function( int x, double z)

would define a function that takes an integer and a floating point and returns a floating point value.
