Array in C Language - Quiz

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 };

Array passed as an argument to a function is interpreted as
  • A Address of the array.
  • B Values of the first elements of the array.
  • C Address of the first element of the array.
  • D Number of element of the array.

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

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

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

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>
void main()
{
    float arr[] = {12.4, 2.3, 4.5, 6.7};
    printf("%d", sizeof(arr)/sizeof(arr[0]));
}

  • A 5
  • B 4
  • C 6
  • D no output

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 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

What will be printed after execution of the following code? 

void main()
{
      int arr[10] = {1,2,3,4,5};
      printf("%d", arr[5]);
}

  • A Garbage Value
  • B 5
  • C 6
  • D 0
