Array in C Language - Quiz

What is right way to Initialize array?

  • Aint num[6] = { 2, 4, 12, 5, 45, 5 };
  • Bint n{} = { 2, 4, 12, 5, 45, 5 };
  • Cint n{6} = { 2, 4, 12 };
  • Dint n(6) = { 2, 4, 12, 5, 45, 5 };

What will be the output of following program code? 

#include <stdio.h>
int main(void)
{
    char p;
    char buf[10] = {1, 2, 3, 4, 5, 6, 9, 8};
    p = (buf + 1)[5];
    printf("%d", p);
    return 0;
}

  • A5
  • B9
  • C6
  • Derror

Size of the array need not be specified, when

  • AInitialization is a part of definition
  • BIt is a declaratrion
  • CIt is a formal parameter
  • DAll of these

Consider the following type definition. 

typedef char x[10];
x myArray[5];
What will sizeof(myArray) be ? (Assume one character occupies 1 byte)

  • A15
  • B10
  • C50
  • D30

What will be the output of the following code? 

void main()
{
      int a[10];
      printf("%d %d", a[-1], a[12]);
}

  • A0 0
  • BGarbage value 0
  • C0 Garbage Value
  • DGarbage vlaue Garbage Value

What does the following declaration mean? int (*ptr)[10];

  • Aptr is array of pointers to 10 integers
  • Bptr is a pointer to an array of 10 integers
  • Cptr is an array of 10 integers
  • Dptr is an pointer to array

Array passed as an argument to a function is interpreted as

  • AAddress of the array.
  • BValues of the first elements of the array.
  • CAddress of the first element of the array.
  • DNumber of element of the array.

What will be the output of the program if the array begins at 65472 and each integer occupies 2 bytes? 

#include
void main()
{
    int a[3][4] = {1, 2, 3, 4, 4, 3, 2, 1, 7, 8, 9, 0};
    printf("%u, %u", a+1, &a+1);
}

  • A65474, 65488
  • B65480, 65488
  • C65480, 65496
  • D 65474, 65476

Which of the following function is more appropriate for reading in a multi-word string?

  • Ascanf()
  • Bgets()
  • Cprintf()
  • Dputs()

Which of the following correctly accesses the seventh element stored in arr, an array with 100 elements?

  • Aarr[6]
  • Barr[7]
  • C arr{6}
  • Darr{7}
