Pattern Printing Coding Programs (Star, Number, and Alphabet)

Learn core concepts, essential formulas, and attempt practice questions designed on the latest TCS NQT testing patterns.

Key Concepts & Formulas

  • 1Inner loop handles columns print; outer loop controls line rows count.
  • 2Use space calculations for pyramid pattern setups.

TCS NQT Style Practice Questions

Practice Question 1

How many stars print for: for(i=1;i<=3;i++) for(j=1;j<=i;j++) print('*')?

A) 6
B) 9
C) 3
D) 5

Correct Answer: A) 6

Step-by-step Solution: i=1: j runs 1 time. i=2: j runs 2 times. i=3: j runs 3 times. Total prints = 1 + 2 + 3 = 6 stars.

Practice Question 2

What loop condition prints a right-angled triangle?

A) Inner loop terminates at outer variable value
B) Inner loop runs to N always
C) Outer loop runs backward
D) Constant nested loops

Correct Answer: A) Inner loop terminates at outer variable value

Step-by-step Solution: To print incrementing counts per row, the column loop must terminate at the current row index (j <= i).

Study Pro-Tip

Draft row-column indices tables on grids to find exact line spaces formulas.
