  • Question
  • Size of short integer and long integer can be verified using the sizeof() operator.


  • Options
  • A. True
  • B. False

  • Correct Answer
  • True 

    Explanation
    True, we can find the size of short integer and long integer using the sizeof() operator.
    Example:

    
    #include<stdio.h>
    int main()
    {
        short int i = 10;
        long int j = 10;
        printf("short int is %d bytes.,\nlong int is %d bytes.",
                sizeof(i),sizeof(j));
        return 0;
    }
    

    Output:
    short int is 2 bytes.
    long int is 4 bytes.
