Code Challenge: Functions [Problem Solved]

I'm stuck at this challenge from Objective-C Basics. It's asking to write a function named "addTwo" that accepts two float numbers as arguments. The function should also return a float which is the sum of the two arguments passed to the function.

// I don't really know what they mean by float numbers, but can't find the way through this code, thought I was doing it right...

My code:

int addTwo(int a, int b);
int main()
{
    int hi = 22;
    int ho = 24;
    printf("addTwo %d", addTwo(hi, ho));

    return 0;
}
int addTwo(int a, int b)    {
    return a + b;
}

float is a primitive data type. It is a number that contains decimals. you have the right idea, you just need to change all your ints to floats

for example 

float addTwo(float a, float b)    {
    return a + b;
}

Ohh! my fail, I think I must rest ^^ Forgot about the float variables.

Int - Float - Char

Thank you Stone! Really appreciate your help :)

wish I had found this before I tried what felt like a thousand other options I went through. I didn't realize the challenge wanted the variable "addTwo" to be created as a float, so I put the following as my first attempt.

int addTwo (float a, float b)[ return a + b; }
