number of elements in an array between upper and lower bounds program
Write a C program that creates a 4x4 2d array, fill it with user-defined values and display (separately) the sum of the diagonal as well as the upper and lower triangular elements.
d ut ut ut
Lt d ut ut
Lt Lt d ut
Lt Lt Lt d
where: ut means upper triangular
Lt means lower triangular
d means diagonal elements
Write a program in C that prompt the user to enter temperature in either degrees Celsius or Fahrenheit. These program then computes to a different unit. Use function.
Using linked list , take two input polynomials from user and create a new polynomial such that it first multiplies the first polynomial by x^(degree of second polynomial) and then adds it to the second polynomial .
Write a program in c language that could prompt the user to select a mathematical figure either circle or rectangle . The program then compute the perimeter of the figure.

You can also make a list of numbers, ey? Let's go and have some fun in tweaking the values of each element, but let's give it some twist to add on some fun to the code.
Let's have a go at it!
The squares and cubes of the elements in the array.

Miss Ural wants to buy colors for Holi, and that too, at the cheapest cost!
There are N shops selling colors near Ural's house, where the i′th shop sells colors at rate of Ri for one unit. Also, i′th shop is located at a distance of Di kilometers from her house. Life was simple, but then petrol and fuel prices soared up. The current price of petrol to travel one kilometer is K
Find the minimum cost at which Miss Ural can buy one unit of color. she does not need to return back home.
For test case, output minimum cost to purchase 1 unit of color.
You are given an array of N non-negative integers: A1, A2, ..., AN. An alternating subsequence is a subsequence in which the indices of any two consecutive elements differ by exactly two in the original array. That is, if Ai1, Ai2, ..., Aik is some subsequence, then for it to be an alternating subsequence, (i2 - i1 = 2), (i3 - i2 = 2), and so on should all hold true. Among all alternating subsequences, find the one which has maximum sum of elements, and output that sum.
The first line of the input contains an integer T denoting the number of test cases.
The first line of each test case contains an integer N denoting the number of elements in the array.
The second line contains N space-separated integers A1, A2, ..., AN denoting the array A.
For each test case, output a single line containing the answer.
A subsequence with only a single integer is also an alternating subsequence.
1 ≤ T ≤ 10
1 ≤ N ≤ 105
0 ≤ Ai ≤ 105

Whole numbers are great, but I think we should also pay attention to decimal numbers, too.
So, how about we make a program that involves a lot of decimals?
1. A series of float numbers
The first multiple lines containing message prompts for float numbers.
The last line contains the sum with 2 decimal places.
Enter a number: 1.1 Enter a number: 1.2 Enter a number: 1.3 Enter a number: 1.4 Enter a number: -1.0 Sum = 4.00

Looping numbers is fun, but it's even more exciting when we combine complex tasks to it, just like looping through a series of numbers and performing a series of code only to special numbers, like odd ones! And today, we're going to do just that.
Are you ready?
1. An integer
The first line will contain a message prompt to input the integer.
The succeeding lines contain the odd numbers.
Enter n: 10 9 7 5 3 1
