- Write a C line to represent the following equation(Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?(Program) Using the at() function, write a C++ program that reads in a string by using getline() and then displays the string in reverse order. (Hint: After the string has been entered and saved, retrieve and display characters, starting from the end of the string.)
- (3) Generate 2000 pseudorandom numbers z; in the same range using the randint function from the random module. Plot z; against Z₁-1 as a scatter plot. (Again the plot should appear automatically, in a separate window to the previous plot.)Q1. Write a C++ program that is used to display 5 bit binary sequence from 00000 to 11111. Use FOR loop. Show the code and output screen. Q2. Write a C++ program that define an empty array of size 10 and user has to input marks scored by ten students one at a time. The program should show first three top marks. Show the code and output screen. Q3. Write a C++ program that define a empty array of size 3x3 and accepts nine numbers (with and without decimal points). Display it as three rows and three columns. Also display the transpose of the same array (row to column vice versa). Show the code and output screen. Q4. Write a C++ that create an array of size 10x10, each of its elements is generated using the relation 3i + 4j, where i is the row index and j is the column index. Display array in 10x10 shape. Show the code and output screen. Q5. Write a C++ that accepts a matrix of same size (size is entered by the user) and produce sum and difference of the given matrices. Show the…PYTHON (Uee While Loop) only Write a python program that calculates the populations of foxes and rabbits who live within a certain area of land, as that number changes from year to year. It will take the initial populations as inputs, and then proceed to calculate the year-by-year changes. The following is derived from the “Lotka-Volterra equations”, which you may look up if you desire. Essentially, we will model the foxes and rabbits with 4 constants, and 2 data structures of year-by-year values. They are defined as follows: r[y] # of rabbits in year y f[y] # of foxes in year y α or alpha - birth rate of rabbits β or beta - death rate of rabbits, dependent on # of foxes γ or gamma - birth rate of foxes, dependent on # of rabbits δ or delta - death rate of foxes, caused naturally The formulas we will use are: r[y]=r[y−1]+(r[y−1]×α)−(r[y−1]×f[y−1]×β)r[y]=r[y−1]+(r[y−1]×α)−(r[y−1]×f[y−1]×β) f[y]=f[y−1]+(f[y−1]×r[y−1]×γ)−(f[y−1]×δ)f[y]=f[y−1]+(f[y−1]×r[y−1]×γ)−(f[y−1]×δ) However,…
- Perform the following using DEV-C++ Show your solution Write a program that determines a student’s grade. It reads four test scores (between0 and 100) and calculates the grade based on the following rules: If the average score is 90 or more, the grade is ‘A’. If the average score is between 80 and 90, the grade is ‘B’. If the average score is between 70 and 80, the grade is ‘C’. If the average score is between 60 and 70, the grade is ‘D’. If the average score is less than 60, the grade is ‘F’.Using Dev C ++, create a program: Number Conversion:Convert Octal to Decimal, Binary, and Hexadecimal. Allow the user to input Octal number. Requirements: The program created should include the following structures: conditional looping programmer-defined functions (no header file creation) arrays and/or strings p.s. use beginner code only.Please fill in the blanks for C /*This task creates a program that reads 3 lowercase strings and prints them back with uppercase Scan and print the strings using a function Call a function to convert all the letter to uppercase If they are already uppercase or non-character (symbol), do nothing Otherwise, convert them to uppercase using the ascii table (We can convert the letters right after getting the inputs, but I want to separate them to make the each function shorter and easier to debug). */ #include<stdio.h> #__1__ length 1000 //set a maximum length for our character string /*This function reads in characters from user, and stop when it detects an Enter.
