- Hello, Does anybody have the code for this? Thanks. Gradesa) Write a program that reads in the names and test grades of 5 students from the data file “grades.txt”. Use the split function to separate the names and test scores and convert the test scores to numeric values. b) Calculate the average of the test scores. Display the names, test scores and the average on the screen as follows:Name Grade---------------------Mickey Mouse 90.0Jane Doe 50.0Minnie Mouse 95.0Donald Duck 80.0Daffy Duck 70.0Average Grade: 77.0 d) Prompt the user for a new first name, last name and grade. Append the files “grades.txt” with the new data in the same format as the existing recordsYou are given a filename. Read the names in the file and output only the initials. For example, if the filename is "data.txt", and the file content in "data.txt" is Dumond, Kristin Larson, Lois the output should be: KD LLWhich of the following statements are true?

- Suppose that you have the following statements: ofstream outfile;int numOfJuiceBottlesSold = 35;double costOfaJuiceBottle = 0.75;double revenue;Use this information and write C11 statements to do the following:a. Open the file sales.dat using the variable outfile.b. Write the statement to format the output in the outfile to two decimal places in fixed form.c. Calculate and store the revenue generated by selling the juice bottles in the variable revenue.d. Write the values of the variables numOfJuiceBottlesSold and costOfaJuiceBottle, and revenue in the file sales.dat.e. Write a statement to close the file sales.dat.Code needed for the following: Use the final numerical grade to look up the corresponding letter grade as follows: 90 - 100 = A 80 - 89 = B 70 - 79 = C 60 - 69 = D < 60 = F Use the final letter grade to look up a "witty" comment of your choice, using a SWITCH statement. A statement must be output for each letter grade above. For example: A = "Most excellent work” B = "IMHO You Passed" etc. Request an output file name from the user. Do not “hard-code” the file name in the program. Do not “hard-code” the file name in the program. Check to ensure the output file opens. If it does not open, display an appropriate message to the user and exit the program. For each student, output the following to the console (screen) and the output file in a neat, readable format. Output each input line on one output line. Use manipulators to output values in readable columns: Student Name, Total Points (numerical grade): NN. Letter Grade: X. Depending on letter grade, The witty comment.…This is my min.c int min(int num1, int num2, int num3) { if (num1 < num2) { if (num1 < num3) { return num1; } } else if (num3 < num2) { if (num3 < num1) { return num3; } } else { return num2; } } This is my min.s .file"min.c" .text .globlmin .defmin;.scl2;.type32;.endef .seh_procmin min: pushq%rbp .seh_pushreg%rbp movq%rsp, %rbp .seh_setframe%rbp, 0 .seh_endprologue movl%ecx, 16(%rbp) movl%edx, 24(%rbp) movl%r8d, 32(%rbp) movl16(%rbp), %eax cmpl24(%rbp), %eax jge.L2 movl16(%rbp), %eax cmpl32(%rbp), %eax jge.L3 movl16(%rbp), %eax jmp.L1 .L2: movl32(%rbp), %eax cmpl24(%rbp), %eax jge.L5 movl32(%rbp), %eax cmpl16(%rbp), %eax jge.L3 movl32(%rbp), %eax jmp.L1 .L5: movl24(%rbp), %eax jmp.L1 .L3: .L1: popq%rbp ret .seh_endproc .ident"GCC: (GNU) 11.2.0"

However, it fails to do so. Rewrite the program so that it accomplishes what it is intended to do. (Also, include statements to close the files and any missing code segment.) #include <iostream> using namespace std; int main() { double length, width; ofstream outfile; infile.open("input.txt"); infile >> length >> width; outfile << "Area = " << length * width << ", Perimeter = " << 2 * (length + width) << endl; return 0; }he following expressions (already in the coding box) with open('test1.txt', 'w') as test1_file: test1_file.write("Do you love Python programming?\n") test1_file.write("No, I don't.") create a file named test1.txt with the following content: Do you love Python programming? No, I don't. . Please write the code that reads the content from file test1.txt, and writes the content to file named test2.txt with the sentence "No, I don't" changed to "Yes, I do.". For example: Test Result with open('test2.txt', 'r') as test2_file: print(test2_file.read()) Do you love Python programming? Yes, I do.
- The pressure of a gas changes as the volume and temperature of the gas vary. Write a program that uses theVan der Waals equation of state for gas, to create a file that displays in tabular form the relationship between the pressure and the volume of n molesof carbon dioxide at a constant absolute temperature (T). P is the pressure in atmospheres, and V is thevolume in liters. The Van der Waals constants for carbon dioxide are a = 3.592 L2 · atm/mol2 and b = 0.0427L/mol. Use 0.08206 L · atm/mol · K for the gas constant R. Inputs to the program include n, the Kelvintemperature, the initial and final volumes in milliliters, and the volume increment between lines of the table.Your program will output a table that varies the volume of the gas from the initial to the final volume insteps prescribed by the volume increment. Here is a sample run:The following program is supposed to read the length and width of a rectangle from a file named input.txt and write the area and perimeter of the numbers to a file named output.txt.
