What are function like macros? Convert the following functions into function-like-macros and use them in the main function. float form(int a, int b) int mul(int a, int b) float div(int a, int b) { float c = a +b; float c, d; float d = a-b; c = a; d = b; C = c*c; d = did; return c/d; return sqrt (c+d); { int c; c = a*b; return Ci Figure 3(a) Figure 3(b) Figure 3(C)
