- Write a program to read a file and print that in haskell language on console. You should maintain like if any blank line in file then it must be on console.*Needs to be done in Haskell* You are to write a version of the Unix cp program where then this program would copy a file and let you rename it. (for this program you can just show the basic functionality and ignore the specific flags)Which of the following are advantages of inline function declarations in C++ or the "Pragma Priority (x)" in Ada? they do not save push/pop variable overhead on the stack when it is called there is a lookup time required at runtime which is the same as an external function call during compile tim. Please type answer no write by hend.

- The following problem is related to System Calls in OS. I have given the coding question as well as my own approach to the question. ***Please do not give me any new solution; just tell me what modification my code needs in order to give the expected output. *** Coding Problem: Write a c program that will open a file given from the command line argument and then it willask the user to input strings that will be written to that file. It will continue to ask the user toenter a string as long as the user enters “-1”. If the given file does not exist in the directory, thenyour program will automatically create the file.

Uses at least one of the standard libraries.Write a complete C++ program in one file which takes a double value from the user, cubes it, and prints the result. Your program must use a function which takes a parameter for the value to be cubed and returns the result by reference. The function may not print anything or read anything directly from the user (i.e. no cin/cout in the function). Hint: n cubed is defined as n*n*n.
