Function call another function

How do you call a function in a function?

This is the function:

Code:

---

int comStaRatio(int comments, int statements)
{
    int ratio=1;
   
    ratio=comments/statements;
   
    return(ratio);
}

---

comments and statements will be two other functions both returning int values.
So when called I will do:

Code:

---

printf("Comment to statement ratio: %d\n", comStaRatio(comCount(file_pointer), staCount(file_pointer)));

---

but this doesn't work. Why?

Thanks.

How does it not work?

I'm unsure, but it returns 0.

That sounds okay, if the result of comCount(file_pointer) is less than the result of staCount(file_pointer).

Code:

---


printf("Comment to statement ratio: %d\n", comStaRatio(comCount(file_pointer), staCount(file_pointer)));

---

First you are missing your second argument to printf. How are you to use staCount()?

Well what are the values of comments and statements in the function?

crap never mind my last post!

After actually looking more closer, your %d qualifier should be %f.

If your division is less than 0, that is what you will get. What level of precision are you needing with this calculation?

laserlight you are a legend! I can;t believe i was so stupid not to realise that the answer actually is 0!!!

Thank you!

Uh oh. Whenever I try to change the function and the function call to float it doesnt work!

Code:

---

float comStaRatio(int comments, int statements)
{
    float ratio=1;
   
    ratio=(float)comments/(float)statements;
   
    return(ratio);
}

---

Call:

Code:

---

printf("Comment to statement ratio: %.2f\n", comStaRatio(comCount(file_pointer), staCount(file_pointer)));

---

Any ideas?

Code:

---

printf("Comment to statement ratio: %.2f\n", comStaRatio(comCount(file_pointer), staCount(file_pointer)));

---

See something that dosent match?

Edit: Ignore it does >_<

No I can't say that I do.
The two parameters you have in green are ints yes but comStaRatio returns a floating point number.

It looks okay to me. I suggest that you post the smallest and simplest compilable code that demonstrates the problem.

Nope.

No, I don't. Perhaps you could elaborate on what you think is wrong.

Yeah I edited my post. I just read the brackets wrong o_0
