1. Write C++ statements which declare the parkingSpots as a of type two-dimensio

Question

1. Write C++ statements which declare the parkingSpots as a of type two-dimensional int array, sized NUM_OF_ROWS by NUM_OF_COLS, then write another statement which calls the function from the previous problem with this new array.

2. Write the C++ definition of a void function with a single formal parameter of type two-dimensional int array, sized NUM_OF_ROWS by NUM_OF_COLS. Assume NUM_OF_ROWS and NUM_OF_COLS are defined integer constants. Have the function read from common input in order to fill the contents of the array which is passed in.

3.

3. Given the following C++ code

char name[8];

strcpy(name, " Robert");

mark the following statements as ‘‘Yes’’ if they precisely output Robert. Otherwise, mark the statement as ‘‘No’’ and explain the reason why.

a. cout << name;

Answer:

b. for(int j = 0; j < 5; j++)

   cout << name[j];

Answer:

c. int j = 0;

while(name[j] != '')

   cout << name[j++];

Answer:

d. for(int j = 0; j < 8; j++)

   cout << name[j];

Explanation / Answer

1. int parkingSpots[NUM_OF_ROWS][NUM_OF_COLS]

    function call with the array can be

    void f(int data[][]); if such is function signature then
    calling will be f(parkingSpots);

2. void f(int data[NUM_OF_ROWS][NUM_OF_COLS]);

   void f(int data[NUM_OF_ROWS][NUM_OF_COLS]){
       for (int i=0; i<NUM_OF_ROWS; i++){
          for (int j =0; j<NUM_OF_COLS; j++){
              cin >> data[i][j];
          }
       }
   }

3. a True

   b False Robert is of length 7 but the loop is going upto 5

   c True

   d True
