Section-A
Write the programs for the following problems in C.
1. Swap two variables x,y without using a temporary variable.
2. Write algorithm for finding the GCD of a number.
3.Write a program for reversing the given string.
4. The integers from 1 to n are stored in an array in a random
fashion. but one integer is missing. Write a program to find the
missing integer.
Ans): Hint : The sum of n natural numbers is = n(n+1)/2.
if we subtract the above sum from the sum of all the
numbers in the array , the result is nothing but the
missing number.
5. Some bit type of questions has been given on pointers asking to

it is correct explain what it will do. (around 15 bits).

· some questions are Code Snippet based.
* Some questions are compiler based i.e. given code snippet will compile or not, if not the reason.
* some question are from the prfix/postfix inc/dec operation based code snippets.
* More than 3 question are based on the sorting algorithms.
* some questions are from the pointers based.
* Code snippets involving memory allocation function.
* All the questions are from c
Some of the question ,i remember, are the following
1.
#include
#define sqr(x) (x*x)
int main()
{
int x=2;
printf("value of x=%d",sqr(x+1));
}
What is the value of x?
a)4 b)5 c)None d)can not compile
Ans: 5
2. what is the wrong in the following program?
#define LBRACKET {
#define RBRACKET }
#define MAIN main
int MAIN()
LBRACKET
int x=2;
printf("%d",x);
RBRACKET
a) This program will compile
b) compilation error
3.
#include
int main()
{
int x=4;
{
{
{
int x=2;
printf("%d",x);
}
}
}
}
a) 4 b)2 c)Nesting not allowed d)dependent on the compiler
4. Go through the following code sinippet
char a[20];
a="Hello Orcale Test";
will this compile?
a) Compilation Error b) Strings are allowed in c but cannot be assigned directly.
c) dependent on compiler
d) will work fine.
5. the expression a+b*c should be conveted to +a*bc. Using tree structure,
Which traversal is the correct one?
a) Postfix traversal b) prefix traversal c) infix traversal d)None
6. what about brk, sbrk
a) system calls b) function calls c) user defined functions
7. Why the use of alloca() is discouraged?
8. Macros support multiple arguments ?
9. the header file
a) contains only compiler directives and extern variables
b) contail only structures and unitions
c) a & b
10. what about "char *(*(*a[])())();"
