Write a C function that receives three floatingpoint number
     Write a C function that receives three floating-point number as input argument. The function returns the value of the one with the maximum absolute value. For example, if the numbers are 12.1, -13.2, and 0.1, respectively, then the function will return -13.2 because it has the maximum absolute value of 13.2. You are not allowed to use abs() function of C standard libraries. 
  
  Solution
float abs (float n1, float n2, float n3) {
 float s,s1,s2;
 return n1 < 0 ? -n1 : n1;
 s1=n1 < 0 ? -n2 : n2;
 s2=n1 < 0 ? -n3 : n3;
 if (s>s1 && s>s2)
 return s;
 else if(s1>s && s1>s)
 return s1;
 else
 return s;
 }
