SUBEX AZURE Placement test paper pattern and selection procedure with sample questions for 25th March 2008 latest subex employment test.

They have 5 rounds:
1) Written test
2) 3 technical interviews
2) 1 HR interviews

Written test: Consists of C and C++ questions.

Two sections:
 1. Objective (20 questions: 30 minutes)
 2. Programming (2 questions, Answer any 1, Time – 30 minutes)

Some of the objective type / multiple choice questions are:
1.  enum sample{x,y=2,z,a=60,b}
……..
……..        printf(“%d”,b);
 opt: a. 0 b. 53  c.61 d.3

2. How many time the following code will print “Hello”
void main()
{
printf (“Hello”);
main();
}

C language programs / programming test questions 

3. char str[]=”Hello”;
char *p;
char str2[]=”Abc”;
p=str;
p=str2;  
printf(“p=%s”);

Some of the programming qns:
1. Find the occurrance of the following “C” keywords in a given text file.
i. int      
ii. char      
iii. return

Find the occurrance of each keyword seperately and also find the sum of all occurrances. 

The following code will work but may not be an efficient one.
ans:
#include

#include
void main(int argc,char *argv[])
{
FILE *fp;
char s1[]=”int “,s2[]=”char “,s3[]=”return “,ch;
int i,j,k,l,cnt1,cnt2,cnt3;
int l1,l2,l3;
cnt1=j=k=l=cnt2=cnt3=0;
clrscr();
if(argc!=2)
{
printf (“Invalid Arguments\n”);
exit(0);
}
fp=fopen(argv[1],”r”);
if(fp==NULL)
{
printf(“File ‘%s’ Cannot open\n”,argv[1]);
exit(0);
}
l1=strlen(s1);
l2=strlen(s2);
l3=strlen(s3);
for(;((ch=fgetc(fp))!=EOF);)
{
if(ch!=s1[j] && ch!=s2[k] && ch!=s3[l])
{ j=k=l=0;
continue;
}
else
{
if(ch==s1[j])
j++;
else if(ch==s2[k])
k++;
else if(ch==s3[l])
l++;
}
if(l1==j)
{
cnt1++;
j=0;
}
else if(l2==k)
{
cnt2++;
k=0;
}
else if(l3==l)
{
cnt3++;
l=0;
}
}
printf (“\n\nOccurrance of ‘int’=%d”,cnt1);
printf (“\n\nOccurrance of ‘char’=%d”,cnt2);
printf (“\n\nOccurrance of ‘return’=%d”,cnt3);
printf (“\nTotal : %d”,(cnt1+cnt2+cnt3));
fclose(fp);
getch();
} 

2. Program to compare two strings and return 0 if they are equal else return -1.
3. Write a function for eliminating the duplicate elements in an array.
