How do you write a function prototype for a function called protoFunc, which is passed two integer parameters and returns nothing using the C language?
Also, how do you write a function prototype for a function called thatFunc, which is passed two float address pointers and returns a float?
1)
void protoFunc( int, int );
2)
float thatFunc( float *, float * );
Hopefully by just seeing these examples you can understand what is going on in them. Its pretty self explanatory I think. If you have specific questions just ask.
EDIT:
Sorry Salem
You need to understand how function prototypes works.
It's not so difficult, and now if we wan't to make a function called test() that receives two integers as parameters and return an int.Code:type_of_value_returned [...] name_of_function [...] (parameters [...])
[code]
int test(int num1, int num2);
[code]
for the float:
If the identifier that will receive the returned float is called retFloat, then how would you write the statement that would be used to call thatFunc from within the main?
Why?
Because you're taking without giving anything back. We want to know that you're trying, otherwise it's a waste of time helping you out and we have better things to do.
In addition to what's already posted: Read the forum guidelines. Your question may or may not be homework to you, but it sure gives a strong impression of being so.Originally posted by volk
Why?
When all else fails, read the instructions.

Well, I'm trying to make a function that will figure out if a number is even or odd.
I'm also trying to make a function that will draw a parabola based on user input.
I'm sorry if my questions sound like homework, but c'mon, I'm just a beginner. Show a little mercy here, ok?
Don't you guys remember when you were beginners? Huh, do you? Well...do you?
so let's think together, your function should receive 1(or more, if you want) parameter and the same function should return (or not) an value, like, if the number is even, it returns 1 else returns 0.Well, I'm trying to make a function that will figure out if a number is even or odd.
We did tell you how to make this, I did write above how function prototypes work.
Code:type_of_value_returned [...] name_of_function [...] (parameters [...])
We know that you're a beginner, but if we do all your exercises you'll never learn how to do it by yourself.I'm sorry if my questions sound like homework, but c'mon, I'm just a beginner. Show a little mercy here, ok?
Every one remember, but I think at least, I tried to make my exercises, and if I did not understand something, I did try to read the book again and again.Don't you guys remember when you were beginners? Huh, do you? Well...do you?
You're serious?... for what's it worth and not caring about 0.Originally posted by volk

Code:#include <stdio.h> void oddEven(int); int main(void) { int i; for(i=0; i < 21; i++) oddEven(i); return 0; } void oddEven(int number) { if((number % 2) == 0) printf("%d is Even\n", number); else printf("%d is Odd\n", number); }Interesting....I'm also trying to make a function that will draw a parabola based on user input.
No worries.... I'm a newb myself...I'm sorry if my questions sound like homework, but c'mon, I'm just a beginner. Show a little mercy here, ok?
How can I forget?Don't you guys remember when you were beginners? Huh, do you? Well...do you?
I haven't used a compiler in ages, so please be gentle as I try to reacclimate myself. :P
