Consider the following code (which does not do anything significant)int h(int p) {    return p++;}int g(int x, int y) {    int z;   return h(y);}int f(int a, int b) {    if(a % 3 == 0) {        g(a, 2);        } else {        h(a);    }       return 10;}int main() {    int m;    scanf("%d", &m);    if(m % 2 == 0) {        f(m, 20);    } else {        g(20, m);    }       return 0;   }How many functions can be active the same time, in the execution of the above program?

Consider the C program shown below -int sumOdd(int *a, int n){  if(n <= 0) return 0;  else if (*a % 2 != 0) return *a + sumOdd (a + 1, n - 1);  return sumOdd (a + 1, n - 1);}int main(){  int a[] = {1,2, 3, 4, 5 ,6};  printf("%d\n", sumOdd(a, 6));  return 0;}The output of this program is -912158

Select the correct answerOutput by the below given code is:#include<stdio.h>int Function(int x, int *P1, int **P2) {  int y, z;  **P2 += 2;   z = **P2;  *P1 += 3;   y = *P1;   x += 4;   return x + y + z; }   int main() {   int c, *b, **a;   c = 10;   b = &c;   a = &b;   printf("%d ", Function(c, b, a));   return 0;}Options40414344

n the following code,int f(int *a) {  *a  = 20;}int main() { int m = 30; f(&m);}a.The parameter passing is "pass by address", and the "address of m" is passedb.Parameter passing is by value, the value passed is "address of m", and copied into the argument *a c.Parameter passing is by value, the value passed is "m", and copied into the argument a d.Parameter passing is by value, the value passed is "address of m", and copied into the argument ae.The parameter passing is "pass by reference" and variable a is a reference to variable m.

What is the output of the following program?#include<stdio.h> int main() {     int a[5] = {2, 3};     printf("%d, %d, %d", a[2], a[3], a[4]);     return 0; }Select one:Compilation error2, 3, 30, 0, 03, 2, 2
