C- Floating point precision

Question

I have a program:

int main() 
{   
        float f = 0.0f;  
        int i;  

        for (i = 0 ; i < 10 ; i++) 
                f = f + 0.1f; 

                


        

Answer 1

This is equivelent to adding 0.33 together 3 times (0.99) and wondering why it is not equal to 1.0.
