1st tutorial for right angle triangle patterns

For beginners in C language it is very important to understand LOOPING. By understanding how loop works your programming power will improve to next level.

Many students face problem in looping during coding for big programs, they got confuse if more loops are involved in a program. So to eradicate this problem we have tried to clear your concepts as better as we can do it. Here we have explained all small loops from simple to nested loops.

This tutorial explains use of different loops by making different patterns of “*”, “alphabets”, “numbers”.

Now let us take one example of such pattern:

This pattern is of “*” which are arranged in a right angle triangle, so to perform this in program we need to use FOR LOOP. We can use while loop do while loop also but as you know benefit of using for loop is we can initialize counter ,its condition and incrementation or decrementation while other loops only provide condition checking , The coding for this is given as below in snap shot.

Here nested for loop is used.

First FOR loop execute as many times as you enter the lines (size) of patterns you want. Here in this example size is 5 so “k=5”, so [for(i=1;i<=k;i++)] starting from 1 to 5 line will be incremented.

Second FOR loop is for printing “*” , here * is printed in increasing order starting from 1 to ‘k’ (number you have entered) so we have to increment the variable ‘j’ which is use in loop as

[ for(j=1;j<=i;j++)]

Here starting from 1 to the number of preceding loop executes.

Here only one pattern is explained there are minimum 20 patterns only of right angle triangle that can be made by doing little variation such as printing “alphabets” or  “numbers” also applying different ideas of printing numbers and alphabets. To apply that variation all we have to do is just change the printf statement according to our purpose, Other patterns that can be made are:

This is an introductory tutorial which explains only one pattern but we will soon provide all other patterns’ tutorials explaining all programs to its detail. Till then try it yourself, if you are facing any problem in making above shown patterns just comment its pattern code and we will try to sort you out your problem.

So stay tuned for more fun in learning concepts to its core.
