3. Which memory management technique involves dividing the memory into fixed sized blocks?
Ans. Paging

4.  What is video resolution ?

5. The processing speed of a microprocessor depends on _____?
Ans. data bus width


C-Test

1.  What is the output of the program given below

#include
main()
{
char i=0;
for(;i>=0;i++) ;
printf("%d
",i);
}

2. What is the output of the following program

#include
main()
{
int i=0;
fork();
printf("%d",i++);
fork();
printf("%d",i++);
fork();
wait();
}

3.  What is the memory allocated by the following definition ?
int (*x)[10];

4. What is the memory allocated by the following definition ?
int (*x)();

5. In the following program segment

#include
main()
{
int a=2;
int b=9;
int c=1;
while(b)
{
if(odd(b))
c=c*a;
a=a*a;
b=b/2;
}
printf("%d
",c);
}

How many times is c=c*a calculated?

6. In the program segment in question 5 what is the value of a at the end of the while loop?

7. What is the output for the program given below
typedef enum grade{GOOD,BAD,WORST,}BAD;
main()
{
BAD g1;
g1=1;
printf("%d",g1);
}


8.  Give the output for the following program.

#define STYLE1 char
main()
{
typedef char STYLE2;
STYLE1 x;
STYLE2 y;
clrscr();
x=255;
y=255;
printf("%d %d
",x,y);
}

9. Give the output for the following program segment.

#ifdef TRUE
int I=0;
#endif

main()
{
int j=0;
printf("%d %d
",i,j);
}

10. In the following program

#include
main()
{
char *pDestn,*pSource="I Love You Daddy";
pDestn=malloc(strlen(pSource));
strcpy(pDestn,pSource);
printf("%s",pDestn);
free(pDestn);
}

(a)Free() fails
(b)Strcpy() fails
(c)prints I love You Daddy
(d)error

11. What is the output for the following program

#include
main()
{
char a[5][5],flag;
a[0][0]='A';
flag=((a==*a)&&(*a==a[0]));
printf("%d
",flag);
}
