Answer:
Option A(True) is the correct answer for the above question.
Explanation:
- An array is used for the collection variables which is of the same type and uses memory in continuous Passion for the storage.
- When any user wants to use the array then he needs to declare the size and type of the array because array holds the same type of data.
- For example, int a[5] is an array of integer variable whose name is 'a' and the size is 5 in c language.
- Anyone can use the array with the help of the index value of the array. The starting index value is 0 and the ending index value is (size-1) for any array.
- The user can use it by the help of loop, in which the loop variable refers to the index of the array and it starts from 0 and ends in the (size of the array-1).
- It is because the loop executes the same line multiple times.
- The above statement also wants to state, which is defined as above. Hence the above statement is true which is referred by option A. Hence option A is the correct answer.
This statement checks if num1 is equal to the absolute value of num1
For instance,
num1 = 4 and the absolute value of num1 = 4. This would run the code inside the if statement but if num1 = -1 the absolute value of num1 = 1 and the if stamtent would be skipped because -1 does not equal 1
