What is the output of the following C code?

What will be the output of the following C++ code?

Which type of loop can be implemented using the do statement?

#include<stdio.h>

int main()

{

      int h=8;

      int b=(h++,++h);

      printf("%d %d\n",b,h);

      return 0;

}

If you specify more arguments than the format specifiers in a printf() statement, what will happen?

What happens when both of the following C++ programs are compiled and executed?

Consider the following C program:

#include <stdio.h>   int counter = 0;   int calc(int a, int b) {   int c;     counter++;   if (b == 3)     return (a * a * a);   else {     c = calc(a, b / 3);     return (c * c * c);   } }   int main() {   calc(4, 81);   printf("%d", counter); }

The output of this program is 

Consider the C program fragment below which is meant to divide x by y using repeated subtractions. The variable x, y, q and r are all unsigned int.

while(r >= y) { r = r - y; q = q + 1; }

Which of the following conditions on the variables x, y, q and r before the execution of the fragment will ensure that the loop terminates in a state satisfying the condition x == (y*q + r)?

Consider the following two C code segments. Y and X are one and two dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of Y are initialized to 0 and each element X[i][j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of X are in same main memory page frame.

Code segment 1:   // initialize elements of Y to 0   // initialize elements X[i][j] of X to i+j   for (i = 0; i < n; i++)       y[i] + = X[0][i];     Code segment 2:   // initialize elements of Y to 0   // initialize elements X[i][j] of X to i+j   for (i = 0; i < n; i++)       y[i] + = X[i][0];

Which of the following statements is/are correct?

S1: Final contents of array Y will be same in both code segments. S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory. S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory.
