Program Analysis.
( 2 mark for correct -1 for wrong )
In this section small blocks of code were given,for which
an account of errors was to be given and for the codes not
containing any error the output was to be given.
What will be the output of the following programs ?

{
int i,a[10];
i = 5;
a[5] = 10;
a[6] = 9;
a[7] = 8;
a[8] = 0;
a[i] = i++;
printf("%d %d",a[5],a[6]);
}
2. main()
{
int x=10,y=15,z=16;
x=y==z;
printf("%d",x);
}

main()
{
printf("%d %d",x/x,x*3);
}

p=&x;
x++;p++;
printf("%d %d",x,p);
}
6. main()
{
int i=6;
switch (i)
{
default: i+=2;
case 4: i=i-1;
case 5: i+=5;
break;
}
printf("%d",i);
}

char *p;
p=malloc(10);
free(p);
printf("%d",p);
}

{ {
while (*a1) while (*a2=*a1)
*a2++=*a1++; {
} a2++;a1++;
}
}
9. Find if there is any error in the program below, correct it if there eny.
main()
{
char **a;
*a[0]=malloc(10);
*a[4]=malloc(10);
strcpy(*a[0],"hello");
strcpy(*a[4],"world");
printf("%s\t%s\n",*a[0],*a[4]);
