Question 1

in the following code:
int myVal = computeValue(2, 3);

int computeValue (int x, int y) {
    int result = x+y;
    return result;
}

2 is

options:

a parameter

An argument

the function body

the header of the function computeValue

Question 2

When writing
Variable1 == Variable2,
the contents of Variable2 are tested against the contents of Variable1;
If they are equal, then the evaluation will yield true, otherwise it will yield false

options:

True

False

Question 3

When writing
Variable1 == Variable2, the content of Variable2 gets copied in Variable1.

options:

True

False

Explanation / Answer

1) 2 is an argument.

explanation: the values passed to a function call are arguments, where as variables used in function declaration are parameters.

2) True

expln: == is a comparison operator that compares the 2 values and returns true value if they are equal, false otherwise

3) False

expln: == is a comparison operator that compares the 2 values and returns true value if they are equal, false otherwise

4) True

expln: De Morgan's law states:

5) False

6) False

expln: && has higher precedence than ||

7) 4 integers whose indices range from 0 to 3 (follows 0 indexing)

8) False

expln: De Morgan's law states:

9) 7

10) True

11) False ( In java , everything is pass by value. In passing array, the value to reference to the array is passed)

12) All of the above

13) a parameter

15) False

16) a || (b &&c)

17) False ( = is assignment, == is comparison)
