Q$4)$ The following C program, written with user$-$defined functions, finds the quotient of functions $k(a,b,c)$ and $m(x,y,z,t).$ These functions are as follows:

$k(a,b,c)=-10.a^4+2\mathrm{.}5.b-\frac{c^7}{1\mathrm{.}9}$

$m(x,y,z,t)=4*x^2+\sqrt[\phantom{2}]{5}{y}^4-\frac{z^3}{2\mathrm{.}9}+\sqrt[\phantom{2}]{t}1\mathrm{.}2$

Fill in the blanks in the program with appropriate codes.
