Chapter 2, Problem 14E

Explanation of Solution

Nested for loop

• The nested for loops are usually declared with the help of counter variables, conventionally declared as i,j,k and so on for each nested loop.
• The first loop uses i as the counter, while j is used for the second and so on.
• This keeps track of how many times each for loop is run.
• A for loop can have more than one loop nested in it.
• Hence, the nested for loop for printing the number triangle can be written as

  //Execute for loop

  for ...
