C Test - 1

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

[5]. Another structure question
1 Rajiv System Analyst

[6]. INFILE.DAT is copied to OUTFILE.DAT

[7]. A question with argc and argv .
Input will be
