Lesson 1: Getting Started


Activity 1: Find the Factors of 7 between 1 and 100 Using a while Loop

  1. Import all the required header files before the main function:

    #include <iostream>
  2. Inside the main function, create a variable i of type unsigned, and initialize its value as 1:

    unsigned i = 1;
  3. Now, use the while loop adding the logic where the value of i should be less than 100:

    while ( i < 100){ }
  4. In the scope of the while loop, use the if statement with the following logic:

    if (i%7 == 0) {
       std::cout << i << std::endl;
    }
  5. Increase the value of the i variable to iterate through the while loop to validate the condition:

    i++;

    The output of the program is as follows:

    7
    14
    21
    28
    ...
    98

Activity 2: Define a Bi-Dimensional Array and Initialize Its Elements

  1. After creating a C++ file, include the following header file at the start of the program:

    #include <iostream>
  2. Now, in the main function, create a bi-directional array named foo of type integer, with three rows and three columns, as...
