Have a close look to the pattern for a minute so that you can think a little basic things about the pattern.
The pattern is a matrix of?N?rows and columns containing stars(asterisks). Here, you need to iterate through?N?rows, and for each row iterate for?N?columns.
Step by step descriptive logic to print the square number pattern.
for(i=1; i<=N; i++).for(j=1; j<=N; j++).First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
