2. Array in C/C++ Array is a structure type variable. One dimension of array int: int num[3]; There are three integer variables in it: num[0], num[1] and num[2]. You can declare array of int, double, and char. Remember, the index of array starts from zero.

3. Working with array Using while loop to travel all members in an array: int num[3], i; i = 0; while (i < 3) { // do something with num[i] ; i = i + 1; }

4. Working with array Using for loop: int i, num[3]; for (i=0; i<3; i++) { // do something with num[i] ; }

5. Example: input 10 integers int List [10], i; for (i=0; i > List [i]; }

6. Example: output 10 integers that are greater than zero int List [10], i; for (i=0; i 0) cout >> List [i]; }

7. Q1: notes print the numbers all on the same line separated by at least one space. Ex: print the values of num1 and num2 separated by 1 space: cout << num1 << " " << num2; See example runs.

8. Q2: use the file, encrypt.cpp that is provided; add the modification to check for a character entered that is not in the array. Show a sample run, and briefly go through encrypt.cpp

9. Q3: Two dimensional array, matrix[3][4] for (i=0; i<3; i++) { for (j=0; j<4; j++) { // set all of the array entries to zero matrix[i][j]=0; } }

10. Q3: In addition to stopping the robot when 'x' is entered, you also need to stop the robot when it tries to move past the array boundaries--row 0, row 9, col 0, col 9 The robot is positioned in the centre of the map at the start, row 5 and col 5 Show sample run
