Programming Output Evaluation

What is printed by the following C program?

int f(int x, int  py, int  **ppz) void main() {
 {
  Int y, z;
  int c, * b, * * a; * * ppz + = 1;
  z = * ppz c = 4;
  b = &c;
  a = &b; 
 *py + = 2;
  y = *py;
  printf(“ % d”, f(c, b, a));
  x + = 3;
 }
 return x + y + z;
}

Consider the program below:

#include 
int fun(int n, int *f_p) {
    int t, f;
    if (n <= 1) {
        *f_p = 1;
        return 1;
    }
    t = fun(n-1, f_p);
    f = t + *f_p;
    *f_p = t;
    return f;
}

int main() {
    int x = 15;
    printf("%d/n", fun(5, &x));
    return 0;
}

The value printed is

What does the following program print?

#include 
void f (int *p, int * g) 
{
        p = q;
        * p = 2;
}
int i = 0, j = 1;
int main ( )
{
f(&i, &j);
print f ("%d%d  n", i, j) ;
return 0;
}

What is the value printed by the following C program?

#include 
  int f(int * a, int n) {
    if (n <= 0) return 0;
    else if ( * a % 2 = = 0) return *a + f(a + 1, n - 1);
    else return *a - f(a + 1, n - 1);
  }
int main() {
  int a[] = {
    12,
    7,
    13,
    4,
    11,
    6
  };
  print f( % d, f(a, 6));
  return 0;
}

What will be the output of the following C program segment?

Char inChar = ‘A’ switch (inChar ) { case ‘A’ : printf (“Choice A n”); case ‘B’ case ‘C’ : print f(”Choice B”); case ‘D’ case ‘E’ default : printf (“No Choice”) ; }

What output will be generated by the given code segment if: Line 1 is replaced by auto int a = 1; Line 2 is replaced by register int a = 2;

What is the return value of f(p, p) if the value of p is initialised to 5 before the call? Note that the first parameter is passed by reference, whereas the second parameter is passed by value.

int f(int &x, int c) {
  c = c  – 1;
  if (c == 0) return 1;
  x = x + 1;
  return f (x, c) * x;
}

Consider the C program shown below.

#include < stdio.h > 
#define print(x) print f(” % d“, x)
int x;
void Q(int z) {
  z + = x;
  print(z);
}
void P(int * y) {
  int x = * y + 2;
  Q(x); * y = x - 1;
  Print(x);
}
Main(void) {
  x = 5;
  P( & x)
  Print(x);
}

The output of this program is

What is printed by the following C program?

int f(int x, int *py, int **ppz) void main() {
  {
    Int y, z;
    int c, *b, **a; **ppz + = 1;
    z = *ppz c = 4;
    b = &c;
    a = &b; 
   *py + = 2;
    y = *py;
    printf(“ % d”, f(c, b, a));
    x + = 3;
  }
  return x + y + z;
}

What is printed by the print statements in the program P1 assuming call by reference parameter passing?

Program P1(){
  x = 10;
  y = 3;
  func1(y, x, x);
  print x;
  print y;
}

func1(x, y, z) {
  y = y + 4;
  z = x + y + z;
}
