CPTTRN1 - Character Patterns (Act 1)

Using two characters: . (dot) and * (asterisk) print a chessboard-like pattern. The first character printed should be * (asterisk).


You are given t < 100 - the number of test cases and for each of the test cases two positive integers: l - the number of lines and c - the number of columns in the pattern (l, c < 100).


For each of the test cases output the requested pattern (please have a look at the example). Use one line break in between successive patterns.

Just don't forget to process the input for no of test cases before processing the test case itself

easy enough , just do three nested loops , one outer loop for your array or vector , and the inner ones j and k for simple matrix like loops, and print * if j+k %2 ==0 else print .Happy coding.

i have got ac in one go, if you want solution send request mail at somyadeep99@gmail.com
just think about odd even logic.

I thought the question was wrong but it's correct.See odd and even similarity between row no. and column no.
Good luck.
