Given the following declarations: 

int num [10] = {23, 3, 5, 7, 4, -1, 6, 12, 10, -23}; 
int i = 2;

What happens if you modify the elements of an array inside a function that received it as a parameter? 

What does the strcmp() function return if the two strings it receives as arguments are the same? 

In the below statement,

x and y are

uninitialized pointers to int. That is, they are pointing to some random address

that may or may not be valid address.

int * x, y;

What is the ASCII value of the NUL character (\0) used to terminate a string?

Fix the bugs in the following program by rewriting only those statement(s) that need to be modified:

#include <stdio.h>
int main() {
    int *ptr, i = 10;
    ptr = &i;
    i += 20;
    printf("Value of i is %d and is stored at %d.\n", ptr, *ptr);
    return 0;
}

Which operator is

used to access the value stored at the address held by a pointer?

Given the following code:

1  int arr[] = {5, 10, 15, 20, 25, 30};
2  int *ptr1 = arr;
3  int *ptr2 = ptr1 + 5;

If the base address of

arr is 4001, what will be the value of

What is the significance of the *ptr notation on the left-hand side (LHS) of an assignment statement?

#include <stdio.h>
#include <string.h>
void foo(char []);

int main()
{
  char arr[40] = "Plaksha";
  printf("%d, %d\n", sizeof(arr), strlen(arr));
  foo(arr);
  return 0;
}

void foo(char p[])
{
  printf("%d, %d\n", sizeof(p), strlen(p));
  return;
}
