6. Size of the array need not be specified, when
- Option : A
- Explanation : Consider the following declaration double balance[] = {1000.0, 2.0, 3.4, 17.0, 50.0}; If you omit the size of the array, an array just big enough to hold the initialization is created. So, correct option is 'A'.
- Option : C
- Explanation : One element takes three memory words so memory location 1120, 1121, 1123 stores first element. A[49] will be stored at location 1264, (1120+(48*3))
- Option : C
- Explanation : Only element 70 violates the rule. Hence, it must be shifted to its proper position. Step1: swap(10, 70) Step2: swap(40, 70) Hence, only 2 interchanges are required.
