Fortran Linking Multiple Files Together: I have a main fortran file. This file calls on ProgramA, ProgramB and ProgamC. The function to compute the area is pi x radius^2 x A for programA, pi x radius^2 x B for progam B and the same for programC.  I'm not sure what to put down for ProgramA.f90, ProgramB.f90 and ProgramC.f90 it has inputs for radius and A, B or C respectively. I also need a printout once the functions/programs ProgramA, ProgramB and ProgramC are callled. This is my main.f90: program practicedynamo     implicit none     real:: A,B,C, radius     A = 10     B =5     C = 2     radius = 3     !read*,radius     call programA(radius,A)     call programB(radius,B)     call programC(radius,C) end program practicedynamo

Develop a C++ program that reads an unsigned number in some base and outputs theequivalent value in a target base. The input file providing these values will be organized toallow for comment lines and blank lines along with data lines. Use only a single source file so Ican more easily script the downloading and compiling of your submissions.Your program must require a single command line argument, the name of an input file. Thisinput file will consist of any number of lines, each falling into one of three varieties:1. Comment - These lines always start with an at-symbol ('@') and should be completelyignored.2. Blank line - Used to visually organize the input file and should be completely ignored.3. Data line - These are the ones your program will process and are described below.Data lines will all have exactly 3 items separated by a single space character and end with anewline:1. an input base (2 through 36) identified in decimal. Digits representing coefficientsbetween 10 and 35 will…

Can anyone help me with these coding questions

Please help. Use strtol and strtod.

Write a C code to take input from an input .txt file and write into an output file. The input file should have int type values and the output file should contain the square of each inputfrom the input file. Must use file type pointers implementation. A sample input and output are given as follows:Input:1 2 3 4 5Output:1 4 9 16 25

Write a C++ program that read 12 integer values from user, store values in Matrix of 4 X 3. Create another Matrix of 4 X 3, divide each element of Matrix1 by five, and store the result in the Matrix2. Print Matrix A, with heading shown, correctly spaced.Print Matrix B, with heading shown, correctly spaced.Your Program should display output as follows:

Make a C program that gets a source file name from a user. If the file does not exist, it will generate a proper error and exits. If the file exists, it also gets the name of two more files from the user, say destination1 and destination2. These files don't need to exist as they are files that need to be written to. If the files cannot be opened for writing, a proper error will be generated.     The program then reads the source file line by line. It will copy every line that has a digit in it to destination 2 and lines that have no digit in them to destination 1. Feel free to use ctype's isdigit() function to identify digit characters.   Example: If source file is: Hi My name is Veria Hello My name is John. How can I help you? I have a problem with my giga bit internet. The speed should be around 1000 but it's just 200 Sure! I can help with that. Can I have your number in case we get disconnected? Sure! My number's 647-123-1234   First file (destination 1) should be Hi My name is…

in C program please

Write a program in C++ to swap two numbers using function. Test Data: Input 1st number: 2 Input 2nd number: 4 Expected Output: Before swapping: n1 = 2, n2 = 4 After swapping: n1 = 4, n2 = 2 1/1
