Write a program that uses 3 command line arguments to search a list of float numbers in a file and prints out the result of whether the number was found or not on the console. Also, it prints the array in the reverse order (not sorted but reverse order of how the numbers were read in). The first argument is the name of the input file which has the numbers to be searched, the second is an integer specifying how many numbers are in the input file and the third argument is the float number being searched for. Use dynamic memory allocation for the array and use a function (that returns a boolean value) to do the searching. Also make sure in the beginning of your program, that the program will execute only if exactly three arguments (other than executable name itself) are specified at the command line.

Write a program that can read in a rank 2 array from an input disk file and calculate the sums ofall the data in each row and each column in the array. The size of the array to read in will bespecified by two numbers on the first line in the input file, and the elements in each row of thearray will be found on a single line of the input file. Use allocatable arrays that are adjusted tomatch the number of rows and columns in the file each time the program is run. An example ofan input data file containing a 2 row × 4 column array is shown below:
Write a program to use parallel arrays to save User ID and Password. Ask the user to enter the user ID and Passwords for 3 users Save the above information in two parallel arrays (using the same index for each user) After the input is completed, ask the user to enter any user ID and then ask the password for that ID. Confirm if the User ID and pas sword match, if not ask the password again.
I have a file name fileReading1.csv In that file there is (exactly as written): 73.2 42.5 35.7 17.1 28.5 91.6 34.9 12 19.3 Using PYTHON How can I open that file then, using a “for line in file:” formula to transform this string into numbers into an array ? P.s : I need to transform it like that without typing them again : array=[73.2,42.5,35.7,17.1,28.5,91.6,34.9,12,19.3] Using PYTHON Images as support.

Write a program in C that prints a 10x10 matrix of random integers (0 - 10000) onscreen. Then using shell pipes, “sort” command and stream redirection, sort this outputaccording to 3rd column and save the sorted matrix in a file named “sorted.txt”. Saveyour file as ID-hw1.c (e.g. c1112345-hw1.c). Submit both your C code and terminalcommands (as comment lines in your source code).
write a program that will open a file called “story.txt”and count the number of occurrences of each letter from the alphabet in this file.At the end your program will output the following report:Number of occurrences for the alphabets:a was used – times.b was used – times.c was used – times…. …and so, onAssume the file contains only lower-case letters and for simplicity just a singleparagraph. Your program should keep a counter associated with each letter of thealphabet (26 counters) [Hint: Use array]Your program should also print a histogram of characters count by addinga new function print Histogram (int counters []). This function receives thecounters from the previous task and instead of printing the number of times eachcharacter was used, prints a histogram of the counters. An example histogram forthree letters is shown below) [Hint: Use the extended asci character 254]:
Write a program to ask the user for the number of arrays he wants to maintain and then populate eacharray by taking elements from the user. Merge all these arrays in another array and finally remove duplicateelements from the merged array.
Write a program that: includes a function that reads integers consisting of students’ test scores in the range of 0-200 from a file into a one-dimensional array of size 30 includes a function to calculate the mean (add all the scores and divide by the number of scores) includes a function to calculate the median (sort the scores and then find the score in the middle—if there is an odd number of scores, the median is the middle score; otherwise, it is the average of the two middle scores) includes a function to calculate the mode (most frequently occurring score) includes a function to calculate the standard deviation includes a function to determine the number of students having scores in each of the following ranges: 0-24, 25-49, 50-74, 75-99, 100-124, 125-149, 150-174, 175-200 and output each score range followed by the number of students within that range includes a function to print everything to an output file Clearly identify all output. Do not use global variables. Your main…
In python: Create a function file called fibonacci that when sent aninteger (n) it returns a vector (fib). The vector “fib” contains the first “n” elements of theFibonnacci sequence.Note that the first two numbers of the Fibonacci sequence are 1 and 1, but then everynumber after is just the sum of the previous two numbers. So 1+1 =2 and then 1+2 =3and 2+3 =5 and 5+3=8 and so forth. So a Fibonacci sequence looks like:1 1 2 3 5 8 13 21 34 55 89....In the command window (see below), call your function file in a single command thatcreates a vector “f” which is the first 30 elements of the Fibonacci sequence
Use Java to properly read the data from the text file, then creates a two-dimensional array with the assignment specifications. After that, a proper slice is taken from the two-dimensional array. All is printed. File Name is IN300_Dataset2.txt Write a Java program that: A. Reads the text file. B. Using that data, create a two-dimensional array that is 2,500 rows by 100 columns. C. Slice the two-dimensional array using a starting column index of 2 and an ending column index of 5. Print the results of the arrays and slice.

Modify the existing vector's contents, by erasing the element at index 1 (initially 200), then inserting 100 and 102 in the shown locations. Use Vector ADT's erase() and insert() only, and remember that the first argument of those functions is special, involving an iterator and not just an integer. Sample output of below program with input 33 200 10: #include <iostream>#include <vector>using namespace std; void PrintVectors(vector<int> numsList) {unsigned int i; for (i = 0; i < numsList.size(); ++i) {cout << numsList.at(i) << " ";}cout << endl;} int main() {vector<int> numsList;int userInput;int i; for (i = 0; i < 3; ++i) {cin >> userInput;numsList.push_back(userInput);} /* Your solution goes here */ PrintVectors(numsList); return 0;} Please help me with this problem using c++.
