In C.Write a recursive function called DrawTriangle() that outputs lines of '*' to form a right side up isosceles triangle. Function DrawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting. Hint: The number of '*' increases by 2 for every line drawn. Ex: If the input of the program is: 3 the function DrawTriangle() outputs: * *** Ex: If the input of the program is: 19 the function DrawTriangle() outputs: * *** ***** ******* ********* *********** ************* *************** ***************** ******************* Note: No space is output before the first '*' on the last line when the base length is 19 #include /* TODO: Write recursive DrawTriangle() function here. */ int main(void) { int baseLength; scanf("%d", &baseLength); DrawTriangle(baseLength); return 0; }

Transcript

00:01 In this question, we have to write a code in python and we have to use, let us look at the approach that we will use to solve this question.

00:16 So, we have to use a function that is drawtriangle in this case.

00:27 So, this function will take an integer that is baselength as input and uses recursion and to draw the right side up isosyllux triangle.

00:40 So, it will use the recursion method.

00:48 Now, in each recursive call, the function will check if the baselength has reached the smallest possible length.

00:56 If so, it will print the length with a single star in such a way.

01:03 So, and nine spaces before it, that is there.

01:07 If the baselength is greater than one, then the function will make a recursive call with a smaller baselength.

01:14 So, this recursive call will draw the upper part of the triangle.

01:19 So, we have to draw a triangle with stars like this in such a way that it will help our condition.

01:29 So, after the recursive call, the function prints the current line which will consist of spaces and this.

01:37 So, there should be spaces also as you can see here and the object also that is this.

01:45 So, let us look at the code for approach on how we are going to do this.

01:52 So, for that, i will write a code in a basic compiler and show you.

01:57 So, the first thing that we are doing here is we will define a drawtriangle function as i told you.

02:08 So, it will take the parameter baselength as you can see here.

02:14 So, now it represents the length of the base of the triangle.

02:19 It uses now recursion to draw the right side up of the isosceles triangle.

02:24 So, now for that, we have to give an if condition.

02:31 So, let us look at how we will do that.

02:33 So, if the first if condition in the first if condition that is this, we check if the baselength has reached 1 which is the smallest possible baselength for the triangle.

02:47 So, now if it is 1, we will execute the following line.

02:52 So, that is why it will print that single star over there.

02:55 So, now what if the baselength is not equal to 1? if it is not equal to 1, then we will move the else block and execute the following...
