Please help me to answer part 1 and part 2

Answer 1

For the moment, I am uploading answer for part 1 only. I don't have VS but I am installing it. As soon as I installed it. I will edit my answer for part 2.

#define macro_2(a, b) (3*a - 3*b*b + 4*a * b - a*b * 10)

int function_1(int a, int b) {
return (3*a - 3*b*b + 4*a * b - a*b * 10);
}

// Part 1:

void part1(int x) {

int m = x, result;

result = (macro_1(m++));

printf("macro_1(%d) = %d\n\n", (++x), result);
  
// Why did this error occur? Please provide the answer in your own words below following "Explanation: "
printf("Explanation: We know that macro put the variable as it is in the equation and then calculate the result; when it pass (++m) to macro, it passes (++4) not 5; so while calculating the macro,it will check the condition either(++4 which become)>0 which evaluates to true and value of expression will be (++5)i.e., 6. In order to get 5, we should pass m++ in place of ++m.\n\n\n"); // (5 points)

Hope it helps. For the query related to part 1, please refer back to me.
