25 Votes Computer languages are not as easy as human languages, they need you to become a computer yourself, think like a computer and  write an algorithm. Computer programs are fun if you take them up as a challenge, as unsolved puzzles. There is lot of fun in taking up the challenge, understandin understanding g the proble m,  writing an algorithm, writing a program and most importantly runnin running g the pro gram and obtaining required output. Here are few challenging C program questions for you. Let’s see how many of them you  would be able to write without seeing the program solution given below. These questions are to print patterns using asterisk(star) character. Comment below if you have tougher pattern questions.

Explanation: This can be seen as an inverted diamond composed of stars. It can be noted that the composition of this figure follows sequential pattern of consecutive stars and spaces. In case of odd row number, the odd co lumn positions will be filled up with ‘*’, else a space will be spaced and vice-versa in case of even numbered row. In order to achieve this we will construct four different right angle triangles aligned as per the requirement. Back to top
