Array in C Language - Quiz

What is the maximum number of dimensions an array in C may have?
  • A 2
  • B 10
  • C 20
  • D Theoratically no limit. The only practical limits are memory size and compilers.

What will be the output of the following code? 

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

  • A 0 0
  • B Garbage value 0
  • C 0 Garbage Value
  • D Garbage vlaue Garbage Value

Size of the array need not be specified, when
  • A Initialization is a part of definition
  • B It is a declaratrion
  • C It is a formal parameter
  • D All of these

What is right way to Initialize array?
  • A int num[6] = { 2, 4, 12, 5, 45, 5 };
  • B int n{} = { 2, 4, 12, 5, 45, 5 };
  • C int n{6} = { 2, 4, 12 };
  • D int n(6) = { 2, 4, 12, 5, 45, 5 };

Consider the following type definition. 

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

  • A 15
  • B 10
  • C 50
  • D 30

Which of the following correctly accesses the seventh element stored in arr, an array with 100 elements?
  • A arr[6]
  • B arr[7]
  • C arr{6}
  • D arr{7}

Which of the following statements are correct about an array? 
1. The array int num[26]; can store 26 elements.
2. The expression num[1] designates the very first element in the array.
3. It is necessary to initialize the array at the time of declaration.
4. The declaration num[SIZE] is allowed if SIZE is a macro.

  • A 1
  • B 1, 4
  • C 2, 3
  • D 2, 4

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);
}

  • A 65474, 65488
  • B 65480, 65488
  • C 65480, 65496
  • D 65474, 65476

Which of the following function is more appropriate for reading in a multi-word string?
  • A scanf()
  • B gets()
  • C printf()
  • D puts()

What will be the output of the program? 

#include<stdio.h>
int main()
{
    int arr[1] = {10};
    printf("%d", 0[arr]);
    return 0;
}

  • A 1
  • B 0
  • C 10
  • D None of these
