  1. Write C++ code to:
    • Create a function called “ReadFile” that:
      • Accepts a filename as input
      • Opens the file for reading
      • Reads an integer from the file and returns it.
    • Create a main function that
      • Asks the user to input a file
      • Passes that file to the “ReadFile” function
      • Prints the returned integer to the screen
        • Extra Credit:
          • Set a default argument of “intfile.txt” for the “ReadFile” function
          • Write an overloaded function of “ReadFile” that accepts two filenames and reads an int from the first and writes it to the other.

Answer #1
#include<iostream>
#include <fstream>
using namespace std;
int ReadFile(string name="infile.txt"){
 fstream inputFile;
 int num;
  //opening the file
 inputFile.open(name);
 //reading num
 inputFile >> num;
 //returning num
 return num;
}
int ReadFile(string name1,string name2){
   fstream inputFile;
   int num;
  //opening the file
 inputFile.open(name1);
 //reading num
 inputFile >> num;
 ofstream myfile(name2);
 //writing to file
 myfile<<num;
 myfile.close();
 return num;
}

int main(){
        cout<<ReadFile("infile.txt","outfile.txt");
}

using Python: Write a function named safe input(prompt,type) that works like the Python input function, except that it only accepts the specified type of input. The function takes two arguments: r prompt: str r type: int, float, str The function will keep prompting for input until correct input of the specified type is entered. The function returns the input. If the input was specified to be a number ( float or int), the value returned will be of the correct...

1. Write a function called compute_discount which takes a float as the cost and a Boolean value to indicate membership. If the customer is a member, give him/her a 10% discount. If the customer is not a member, she/he will not receive a discount. Give all customers a 5% discount, since it is Cyber Tuesday. Return the discounted cost. Do not prompt the user for input or print within the compute_discount function. Call the function from within main() and pass...

In PYTHON please: Write a function named word_stats that accepts as its parameter a string holding a file name, opens that file and reads its contents as a sequence of words, and produces a particular group of statistics about the input. You should report the total number of words (as an integer) and the average word length (as an un-rounded number). For example, suppose the file tobe.txt contains the following text: To be or not to be, that is the...

A. Write C code to create a structure called time_of_day, which stores the current time in hours, minutes, and seconds. All the fields should be integers except for seconds, which should be a floating point value. B. Write a C function called check_time, which takes a pointer to a time_of_day structure as input, and return 1 if the time is valid (0 to 23 hours, 0 to 59 minutes, 0 to 59.999999 seconds) and 0 otherwise. Assume that times are...
