1. What is the output of the program given below
#include
main()
{
char i=0;
for(;i>=0;i++) ;
printf("%d\n",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\n",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
whileloop?

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\n",x,y);
}
9. Give the output for the following program segment.
#ifdef TRUE
int I=0;
#endif
main()
{
int j=0;
printf("%d %d\n",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\n",flag);
}
