Answer 1

In function f(), you are not declared values for a, b, c, d, e.
So it take some garbage values.
First need to give values to those.
And in main function, f(), functions variables are completely different. There scope is local. So it is available outside of their functions...

If you make those variables as global, then variables are available through out program in all functions..

Answer 2

put this above int main to be global :
float a,b,c,d,e,x,answer

remove this line in the f function.:
float a,b,c,d,e

Answer 3

float a,b,c,d,e are not initialized. They are holding garbage value which result undefined behavior.

Put the input numbers into the function.
