EasyTech Placement Paper 2005 APRIL

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

C QUESTIONS PROGRAMMS

1)
main()
{
char a[2];
*a[0]=7;
*a[1]=5;
printf("%d",&a[1]-a)
ANS:

ans may be 1.(illegal initialization)

2)
#include<stdio.h>
main(){
char a[]="hellow";
char *b="hellow";
char c[5]="hellow";
printf("%s %s %s ",a,b,c);
printf(" ",sizeof(a),sizeof(b),sizeof(c));
}

(ans is hellow,hellow,hellow
6,2,5 )

3)
#include<stdio.h>
main()

float value=10.00;
printf("%g %0.2g %0.4g %f",value,value,value,value)
}

(ans is 10,10,10,10.000000)

4)
#include<stdio.h>
void function1;
int i-value=100;
main()
{
i-value=50;
function1;
printf("i-value in the function=",i-value);
printf("i-value after the function=",i-value);
}
printf("i-value at the end of main=",i-value);
functioni()
i-value=25;

THIS IS ROUGH IDEA OF THE PROGRAM
ANS ARE
1)i-value in the function=25;
2)i-value after the function=50;
3)i-value at the end of the main=100;

5)
main()
{
funct(int n);
{
switch(n)
case1:
m=2;
break;
case2:
m=5;
break;
case3:
m=7;
break;
default:
m=0;
}

THIS IS ROUGH IDEA:
(ANS:Out put is m=0)
