  • 2. 

    Choose exactly right range for float data type.

    • 3.8e-38 to 3.8e+38

    • 3.8e-34 to 3.8e+34

    • 3.4e-38 to 3.4e+38

    • 3.4e-34 to 3.4e+34

    Correct Answer
    A. 3.4e-38 to 3.4e+38
    Explanation
    The correct answer is 3.4e-38 to 3.4e+38. This range represents the minimum and maximum values that can be stored in a float data type in most programming languages. The "e" notation represents scientific notation, where the number before "e" is multiplied by 10 raised to the power of the number after "e". In this case, the range starts at 3.4 multiplied by 10 raised to the power of -38, and ends at 3.4 multiplied by 10 raised to the power of +38. This range allows for a wide range of decimal values to be stored, but it is important to note that float data types have limited precision and may not be able to accurately represent very small or very large numbers.

  • 4. 

    Choose exact size of 'signed long int' data type.

    • 8

    • 16

    • 32

    • 64

    Correct Answer
    A. 32
    Explanation
    The correct answer is 32 because a signed long int data type typically occupies 32 bits of memory, allowing it to store integer values ranging from -2,147,483,648 to 2,147,483,647.

  • 5. 

    Choose valid #define statement from below.

    • #define N 5,M 10

    • #define array 11

    • # define max 10

    • #define PRICE$ 100

    Correct Answer
    A. #define array 11
    Explanation
    The given #define statement "#define array 11" is a valid statement. It defines the identifier "array" to have the value 11. This means that whenever "array" is used in the code, it will be replaced with the value 11 during the preprocessing stage.
