----it is not working on x code- #1 says 2 unused variables---- C++ ----------- These 3 questions were answered incorrectly in the expert q qnd a- they had errors . please help if you are another expert out there. this should all be in c++

THIS IS THE CODE THEY GAVE ME

this code is incorrect

#include #include #include

using namespace std;

QUESTION 3

THIS IS THE CODE THEY GAVE ME

incorrect code below

#include #include #include #include #include

void countchar(char *filename) { ifstream fin(filename); char ch; std::string line; int i,j,alpha=0,others=0,digi=0,lines=0; cout64&&i96&&i47&&i

} fin.clear(); fin.seekg (0, ios::beg); cout

cout

cout

}

int main() { char *filename="nameofyourfile.txt"; char a; countchar(filename); return 0; getch(); }

Question 1: Consider a text file named "employees.txt". The file contains data organized according to the following format: John Sarah Mary Jim Smith Johnson Taylor Stewart 10 40 27 25 15 12 13 For instance, "John" is the first name, "Smith" is the last name, "20% is the number of hours per w eek, and yis the hourly rate. Write a program that computes the weekly salary of each employee. The program prints the first name, last name, and weekly salary of each employee in a file named "results.txt". You must use a function to read/process the data from the input file and this function must have parameters
