What is the task of pre-processor? All Of Above Compiling Linking Expanding2. Comment on the below while statementwhile(0 == 0){} It compare 0 with 0 and since they are equal it will exit the loop It will run for ever It has syntax error as the same number is being compared with itself It has syntax error as there are no statements within braces {}3. How many times the below loop will be executed?#include <stdio.h> int main() { int x, y; for(x=5; x>=1; x--){ for(y=1; y<=x; y++)printf("%d\n",y); } } 123451234123121 12345123412345121 123451234512345123451 1121231234123454. Neha is developing an IP telephony software in which the audio is encoded and transmitted by the sender as network packets through a communication channel. At the other end these packets are assembled and processed further.Neha recognizes that there maybe a very large number of packets this number is unknown and which will be processed while more packets are being received .assume that the packets arrive in right order .what data structure should Neha use? List Queue Array Stack5. Which of the following does not require to include math.h header file? pow() sinh() rand() sqrt()6. In c language, if a function return type is not explicitly defined then it defaults to what data type? long int char float int7. The inorder and preorder traversal of a binary tree are d b e a f c g and a b d e c f g, respectively. The post-order traversal of the binary tree is: d e f g b c a d e b f g c a e d b g f c a e d b f g c a8. Which of the following is true? Elements of a linked-list can be accessed only sequentially. Array elements can be accessed and modified(elements can be added or removed) only at the ends of the array while any elements of the stack can be accessed or modified randomly through their indices. An array can have elements of different data types. Array is a dynamic data structure whose size can be changed while stacks are static data structures whose sizes are fixed.9. Which of the following statements should be used to obtain a remainder after dividing 3.14 by 2.1? rem = 3.14 % 2.1; Remainder cannot be obtained in floating point division. rem = fmod(3.14, 2.1); rem = modf(3.14, 2.1);10. Which of this is used to skip one iteration: break return goto continue11. Which of the following is true? realloc() can change the memory size of arrays Unary operator works on only one operand Struct and Union works in same way None of above12. The difference between variable declaration and variable definition is Declaration associates type to the variable whereas definition gives the value to the variable Declaration associates type to the variable whereas definition associates scope to the variable. Declaration and definition are the same. There is no difference. A declaration is used for variables and definitions is used for functions.13. Which is not a string function? strcmp strupr strchr strstr14. A program reads in 500 integers in the range [0…100]representing the scores of 500 students.it then prints the frequency of each score above 50.what would be the best way for the program to store the frequencies? A dynamically allocated array of 550 numbers An array of 50 numbers An array of 500 numbers An array of 101 numbers15. What is a dangling pointer? Points to nothing Point to garbage Value Points to address None of Above16. Predict the Output : float a = 0.1;if(a==0.1)printf(“Yes”);elseprintf(“No”) Yes No17. Which address does a pointer to an array store: Memory address of the third element of the array Memory address of the first element of the array Memory address of the fourth element of the array Memory address of the second element of the array18. Which of the following is NOT a valid storage class in C language? Dynamic Extern Register Auto19. Which is the character array used to accept command line arguments? char argv[] char* argv char* argv[] char argv20.
