*st1=st1[2];
st1[1]=*st1;
free(st1[0]);
free(st1[1]);
clrscr();

getch();
}
// A. Garbage Garbage Oracle
// B. oracle oracle oracle
// C. Hello World Oracle
// D. Core Dump:cannot Print after freeing the memory

Ans: D

2. What is the output in the following program
main()
{char c=-64;
int i=-32
unsigned int u =-16;
if(c>i)
{printf("pass1,");
if(c
printf("pass2");
else
printf("Fail2");
}
else
printf("Fail1);
if(i
printf("pass2");
else
printf("Fail2")
}

3. What will the following program do?
void main()
{
int i;
char a[]="String";
char *p="New Sring";
char *Temp;
Temp=a;
a=malloc(strlen(p) + 1);
strcpy(a,p); //Line number:9//
p = malloc(strlen(Temp) + 1);
strcpy(p,Temp);
printf("(%s, %s)",a,p);
