## HCL Solved placement Papers - C questions - part 2

Here are some solved questions from HCL Placement Papers

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

Compiler Error
Explanation:
Initialization should not be done for structure members inside the structure declaration

2) main()
{
int *j;
{
int i=10;
j=&i;
}
printf("%d",*j);
}

10
Explanation:
The variable i is a block level variable and the visibility is inside that block only. But the lifetime of i is lifetime of the function so it lives upto the exit of main
function. Since the i is still allocated space, *j prints the value stored in i since j points i.

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

Runtime error: Abnormal program termination.  assert failed (i<5), ,

Explanation:
asserts are used during debugging to make sure that  certain conditions are satisfied. If assertion fails, the program will terminate reporting the same. After debugging use,
#undef NDEBUG and this will disable all the assertions from the source code. Assertion is a good debugging tool to make use of..

4)  main()
{
int i;
printf("%d",scanf("%d",&i)); // value 10 is given as input here
}

1
Explanation:
Scanf returns number of items successfully read and not 1/0. Here 10
is given as input which should have been scanned successfully. So
number of items read is 1.
