Sample Paper

 

1. Difference b/n scanf("%s",msg);and scanf("%[\^n]",msg); where msg is a char array.

 

2. What is ure of comma operator in for loop.

 

3. int shw(int *a){

*a = 10;

/* return stmt is missing */

}

 

main(){

 

int p=3,q=4;

 

q = shw(&p);

 

printf("%d %d",p,q);

}

 

4. which is true

 

a. all automatic variables are declared with in the function

b. all variables are automatic

c. all not declared variables are automatic

d. none

 

5. What is recursion. Recursive prog to generate Fibonacci series . Is it a best method?

 

6. write 7*a interms of +,-,<<

 

7. count number of 1's in a 32 bit integer.(i had not remembered whether array or integer).

 

8. main(){

char *s1 = "hello",*s2 ="abce";

strcpy(s1,"");

s2[0] = s1[0];

printf("%d%d",strlen(s1),strlen(s2));

}

10.Algorithm to delete a node in Double linked list.

 

11. Difference b/n fgets,fscanf which u will prefer.

 

Unix

 

12.What is creon and what's diff b/n 'at' command.

13. what is system call and lib function. what's diff b/n them. about execve - explain.
