Write a program that uses the sizeof operator to determine the sizes in bytes of the various data types on your computer system. Write the results to the file "datasize.dat" so you may print the results later. The format for the results in the file should be as follows (the type sizes on your computer might be different from those shown in the sample output): Data type Size char unsigned char short int 1 unsigned short int int 4 unsigned int long int unsigned long int 4 4 4 float 4 double long double 16

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. The data in "indata.txt" should look similar to this, Lara_Croft75 70 91 69 89Chris_Redfield68 88 79 85 94Johnny_Cochran69 98 95 77 80Wanda_Maximoff84 86 98 95 92Luke_Skywalker74 96 80 98 97William_Kurt89 52 99 81 58Samuel_Jackson50 96 50 64 95END_OF_FILE This is supposed to be in python.

Write a program in Python 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 grades of the students into a text file named…
Computer Science For each of the code snippet given below, identify the error and then write code after fixing the error. Given code is the simulation of grep -v command. -v prints all lines that do not match a specific pattern. void grep_inverse(char *filename, char *str) { FILE *fp; char buf[buff_size]; fp = fopen(filename, "r"); if(!fp) { perror(filename); } else { while (fgets(buf, buff_size, fp) != NULL) { if ((strstr (buf, str)) != NULL) printf("%s", buf); } } fclose(fp); }
Write a program that will read in a file of student academic credit data and create a list of students on academic warning. The list of students on warning will be written to a file. Each line of the input file will contain the student name (a single String with no spaces), the number of semester hours earned (an integer), the total quality points earned (a double). The following shows part of a typical data file: Smith 27 83.7 Jones 21 28.35 Walker 96 182.4 Doe 60 150 The program should compute the GPA (grade point or quality point average) for each student (the total quality points divided by the number of semester hours) then write the student information to the output file if that student should be put on academic warning. A student will be on warning if he/she has a GPA less than 1.5 for students with fewer than 30 semester hours credit, 1.75 for students with fewer than 60 semester hours credit, and 2.0 for all other students. The file Warning.java contains a skeleton of the…

For example, if the file contains text Love is free free is love then the function should print free:2 is:2 love:2 def count_word(filename): # YOUR CODE HERE raise NotImplementedError()
Write a program that reads a student's name followed by five test scores. The program should output the student's name, the five test scores, and the average test score. Output the average test score with two decimal places. The data to be read is stored in a file called test.txt. The output should be stored in a file called testavg.txt. test.txt: A file containing the student names and the five test scores for every student.
