1. Spell-it-out!by CodeChum Admin
Are you intimidated with complicated words? Don't be! The trick is to break it down letter by letter!
Let’s create a program that prints out the character in the array index indicated by the input integer. For example, if the array has 3 character elements, 'j', 'r', and 'd', and the inputted integer value is 1, then we print 'r' because 'r' is found at index 1.
Instructions:
In the code editor, you are provided with an array of characters (or a string).Your task is to ask the user for an integer input which represents the index and then print out the character of the string found at that index.Input
1. Index of the array
Output
Enter the index: 4r

This exercise asks you to draw the following target composed of concentric rectangles
(view inserted image)
A target is composed of n rectangles centered on the middle of the target. These rectangles are of dimensions 3x3, 7x7, 11x11 and so on. The largest rectangle is composed of characters "1", the second largest of characters "2", and so on. All other characters are spaces. The character in the center of the target is always a space, and the characters around the target are always "1".
You should draw a target consisting of 3 rectangles by printing it in the console. However, it should be easy to change the number of rectangles, so that you can draw a different target. You can assume, however, that the number of rectangles requested will always be between 1 and 9 inclusive, since the rectangles must be composed of the numbers 1 to 9.
The target must be drawn in a single call to print. You…

Body Mass Index (BMI) is a measure of health on weight. It can be calculated by taking your weight in kilograms and dividing by the square of your height in meters. Write a program that lets a teacher to calculate the BMI of 20 students. The program should use three one dimensional arrays named studWeight that holds the weight (in kilograms), studHeight that holds the height (in meters) and studBMI that holds the calculated BMI for each student. The program contains the following functions: a) readData: This function receives the studWeight and studHeight arrays from the main function. It reads the weight and height for all the students and stored them in the studWeight and studHeight arrays, respectively. b) calBMI: This function receives one element of the studWeight and studHeight arrays. It calculates the BMI of each student based on her/his weight and height, and then store the BMI in the studBMI array. c) display: This function displays the BMI of the students.arrow_forward(Flattening arrays with flatten vs. ravel) Create a 2-by-3 array containing the first six powers of 2 beginning with 2^0.
