Directions:  Study the following mathematical problems. Encircle the right answer.

PART – II
Technical-C

1.If   a b c is input, then the following program results                              

char x,y,z;

printf(“%d”,scanf(“%c %c %c “,&x,&y,&z));

3.Find the output

int a=4,b=6;

printf(“%d”,a= =b);

a) error message           b)0       c)1       d)none             

4.Find output

while(printf(“%d”, printf(“az”)))

printf(“by”);

a) azbybyby…..                                    b) azbyazbyazbyaazby…..
      c) syntax error                                      d) none            

5.Find the output

        main()

       {

         inc(); inc(); inc(); }

     inc(){static int x;

                 printf(“%d”,++x);                                                                 

              }

a) prints 012               b) prints 123     c) prints 3 consecutive but unpredictable numbers    d) prints 111  

6.What will be the output of the following?

main()

{

 int k=35;

printf("\n %d %d", k>40);

                   }   

7.           main()

      {

    int ivar, *iptr;

    ivar=5;

    iptr=&ivar;

    pritnf("%d \n",ivar);

    *iptr=*iptr+1;

   printf("%d \n",ivar);

}

  what is the output

a)5 1      b) 5 0         c) 5 6        d) 5 5      

8.What is the output of the program ? 

             void main()

            {

                                    static int I = 5;

                                    printf(“ I = %d “,i--);

                                    if(i) main();

            }

9.What is the output of the program?  

            void main()

            {

                                    char *p = “%d\n”:

                                    int I =5;

                                    printf(p,I);

            }

10        #include

      int a=45;

      #define a 10

      main()

      {

                  Printf(“%d”,a);

      }

11.Predicts error in followings

        display(char *);

      main()

                  {

                  Char string[ ]=”Hello\0 World”;

            }

                  Void display(char *string)

            {

                  Printf(“%s”, string)

            }

12.       #define C -2

      Main()

      {

                  C=89;

                  Printf(“c=%d”,c);

      }

13.       main()

                  {

                  Enum {A,B=1,C);

                  B=45;

                  Printf(“%d\n”,B);

                  } 

14.With every use of a memory allocation function, what function should be used to release allocated memory which is no longer needed?

15.       char* myfunc (char *ptr)

{

       Ptr+=3;

        Return (ptr);

}

   Int main()

    {

          Char *x, *y;

          X=”HELLO”;

          Y=myfunc(x);

          Printf(“y=%s\n”,y);

          Return 0;

            }

16.       int x[]=(1,4,8,5,1,4);

             int  *ptr,y;

               ptr= x+4;

               y = ptr - x; 

17.What is the output of the following program ?

#include

#include

main() {
typedef union {
int a;a
char b[10];
float c;
}
Union;

Union x,y = {100};
x.a = 50;
strcpy(x.b,"hello");
x.c = 21.50;
printf("Union x : %d %s %f n",x.a,x.b,x.c);
printf("Union y : %d %s %f n",y.a,y.b,y.c);
}

18. What is the output of this Program ?

 main()
{
char *p1=“name”;
char *p2;
p2=(char*)malloc(20);
memset (p2, 0, 20);
while(*p2++ = *p1++);
printf(“%s\n”,p2);
}

19.       main()

{
int x=20,y=35;
x=y++ + x++;
y= ++y + ++x;
printf(“%d%d\n”,x,y);
}

20.       #define swap(a,b) a=a+b;b=a-b;a=a-b;
void main()
{
int x=5, y=10;
swap (x,y);
printf(“%d %d\n”,x,y);
 

             swap2(x,y);
             printf(“%d %d\n”,x,y);

}

int swap2(int a, int b)
{
int temp;
temp=a;
b=a;
a=temp;
return 0;
}

a)10, 5

b) 5,10

c) compilation Error

d) No output
 

21.       Predict the output or error(s) for the following:

#include
main()
{
struct xx
{
      int x=3;
      char name[]="hello";
 };
struct xx *s;
printf("%d",s->x);
printf("%s",s->name);
}

22.       Analyze the output

#include

main()
{
char s[]={'a','b','c','\n','c','\0'};
char *p,*str,*str1;
p=&s[3];
str=p;
str1=s;
printf("%d",++*p + ++*str1-32);
}

23.       #include

main()
{
int a[2][2][2] = { {10,2,3,4}, {5,6,7,8}  };
int *p,*q;
p=&a[2][2][2];
*q=***a;
printf("%d----%d",*p,*q);
}

24.       main()

{
char *p="hai friends",*p1;
p1=p;
while(*p!='\0') ++*p++;
printf("%s   %s",p,p1);
}

25.       main()

{
   static char names[5][20]={"pascal","ada","cobol","fortran","perl"};
    int i;
    char *t;
    t=names[3];
    names[3]=names[4];
    names[4]=t;
    for (i=0;i<=4;i++)
            printf("%s",names[i]);
}

26.       void main()

{
            int  const * p=5;
            printf("%d",++(*p));
}

27.       #include

#define clrscr() 100
main()
{
clrscr();
printf("%d\n",clrscr());
}

28.       Predict the output or error(s) for the following:

#include

main()

{

int i,j;
            for(i=0;i<=10;i++)
            {
            j+=5;
            assert(i<5);
            }

29.       main()
            {
            int i=-1;
            +i;
            printf("i = %d, +i = %d \n",i,+i);
            }

30.       main()
            {
            char *cptr,c;
            void *vptr,v;
            c=10;  v=0;
            cptr=&c; vptr=&v;
            printf("%c%v",c,v);
            }

5 .  _________________ is a memory _management  scheme that permits the physical address space of a process to be noncontiguous.

6.  ______________ is a lightweight process.

8.  _____________ keeps track of a proceses creation tine as well as the cpu time that it consumes during its lifetime

9.  ______________-- required to complete a critical task within a guaranteed amount of time

10.   In polling mode the kernel checks each I/O device if it generated an interrupt or not. True/False?
