Use programming language C:

Write four macros to re-implement the given four functions (1st attachment). Name them: subm, cubem,
minm, and oddm, respectively.

Then, write a main() function to test these functions and macros. Use the following
test cases in the main() to call your functions and macros in this order and observe the results. (2nd attachment)

*The function-macro pair should give different results, like oddf(a++) and oddm(a++).*

int subf(int a, int b) {
return a - b;
}
int
}
cubef(int
a) {
return a* a * a;
}
int minf(int
int
if (a <= b) {
}
else {
}
a, int b) {
}
else {
}
return a;
oddf(int a) {
if (a % 2 == 1) {
return 1;
return b;
return 0;

a = 3, b = 6;
subf(a, b);
subm(a, b);
subf(a++, b--);
a = 3; b = 6;
subm(a++, b--);
a = 3; b = 6;
cubef(a);
cubem(a);
cubef(--a);
a = 3; b = 6;
cubem(--a);
a = 3; b = 6;
minf(a, b);
minm(a, b);
minf(--a, --b);
a = 3; b = 6;
minm(--a, --b);
a = 2; b = 6;
oddf (a);
oddm(a);
oddf(a++);
a = 2; b = 6;
oddm(a++);
// reset a,b values
