Write a program named pl that converts a gray-level image to a binary one using a threshold value: p1 {input gray-level image) {input gray- level threshold} {output binary image}. Select any threshold that results in "clean" binary images from the gray-level ones given to you (a binary image can be saved as a PGM file with 1 as the number of colors in the header). You should be able to use the same threshold value for all images. Please, when you submit your assignment, indicate the value you used in your README file. Apply program p1 to the image two objects.pgm. The goal is to develop a vision system that recoanizes two-dimensional obiects in

Write a program that will sequentially list numbers from 0 to 50, changing its color depending on the size of the number, for example, for numbers from 0 to 10 it will be green, 11 to 22 red and 23 to 35 blue, etc. Limit the screen output speed to about 1 character / second. In order to change colors, you must first use the GetStdHandle function to get a handle to the console, which is similar to getting a file pointer before working with a file. It is done e.g. as follows: HANDLE hConsole; hConsole = GetStdHandle (STD_OUTPUT_HANDLE); The above functions are defined in windows.h Tip 2: Write a utility to find out the colors corresponding to all combinations from 0 to 255. Tip 3: Instructions and sample program for working with time. C language plz with explanation of codes. thanks
Write a program in a single file that: Main: Creates 10 random doubles, all between 1 and 11, Calls a method that writes 10 random doubles to a text file, one number per line. Calls a method that reads the text file and displays all the doubles and their sum accurate to two decimal places.

After every word on a line is spellchecked, it should be written to an output file called checked.txt. The arrangement of words on lines should be the same in the document and in checked.txt. The difference between the document and checked.txt is that in checked.txt each word is in lowercase and there is no punctuation. Also, some words might be changed by the spellcheck process. For example, suppose the document contains the following: The Hunter Moon waxed round in the night sky, and put to flight all the lesser stars. But low in the South one star shone red. Then checked.txt will contain: the hunter moon waxed round in the night sky and put to flight all the lesser stars but low in the south one star shone red (In a real spellchecker, the output will be in the same case as the original, and all punctuation will be retained. For simplicity, we will not worry about case and punctuation.) How to Process Words Which Are Not in the Dictionary The spellcheck method also needs to handle…
Write a program that receives a coded message file(Lab3ExtraCreditCT.txt) from your local espionage agent and decodes it into a file using standard English. The problem is your agent forgot to tell you the key used to decode the message. Fortunately, this is a simple substitution code consistently using 1 alphanumeric character to represent another, this is case sensitive. All other characters are not substituted, so a space will always be a space, a – will always be a –, a @ will always be a @, etcetera. You may use the following table to help you, it contains the most common letters used in the English language in descending order.

Write a program that reads student data from a file, compute their GPA and writes the results to a different file. 1. The user should have the option to either enter their text file that contains the student grades or use the provided text file that contains theinformation.

Assume that you will be given a *.txt file, which in the same format of RandSource.txt(attached). The file has three numbers at each line. Numbersare separated with a space. All number are in the range of [0, 50]. The first two numbers indicate a range. The third one shows number of random numbers to be generated in the range of first two numbers. The range always given in first < second order. If not, raise an error. For instance, 2 5 7 means that you need to generate 7 random numbers in the range of 2 - 5 (including 2 and 5). You need to develop a complete C++ program to read each line from the .txt file and print the result on screen in a formatted way. The output format will be <first number> - <second number>: <random numbers > . For the above example, the output to screen should be 2 - 5: 6 5 4 6 3 7 5The attached input file has,3 6 82 19 104 12 41 6 07 4 30 8 310 9 8Your program should generate this (or with different random numbers) output for this file3…
Write a program that reads student information from a text file, then creates a text file that records the course grades of the students and a final grade. Each row of the .txt file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student, each separated by a space. A sample of the student information is provided in StudentInfo.txt below. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: • Read the file name of the .txt file from the user. • Open the .txt file and read the student information using readline() or readlines(). • Compute the average exam score of each student. • Assign a letter grade to each student based on the average exam score in the following scale: ◦ A: 90 =< x ◦ B: 80 =< x < 90 ◦ C: 70 =< x < 80 ◦ D: 60 =< x < 70 ◦ F: x < 60 • Output the first names, last names, exam scores, and letter…
Write a program that first reads in the name of an input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words and their frequencies (the number of times each word appears in the file) without any duplicates. Ex: If the input is: input1.csv and the contents of input1.csv are: hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy the output is: hello 1 cat 2 man 2 hey 2 dog 2 boy 2 Hello 1 woman 1 Cat 1 Note: There is a newline at the end of the output, and input1.csv is available to download.
