Note: The Answers given here are what i wrote, May not be correct.
1. Aptitute test : 15 Minutes, 20 Questions
Towards the middle questions are easy than from the front.
eg. Product of three consecutive nos. 210. What is the sum
of two least numbers?
ans.: 5 * 6 * 7 = 210 , sum = 11 is answer
eg. If the area of the sqaure is increased by 69 % how

1]. The following variable is available in file1.c
static int average_float;
all the functions in the file1.c can access the variable
[2]. extern int x;
Check the answer
[3]. Another Problem with
# define TRUE 0
some code
while(TRUE) { some code
}
This won't go into the loop as TRUE is defined as 0
[4]. A question in structures where the memebers are dd,mm,yy.
mm:dd:yy 09:07:97
