Question

Using Clion (an app that could use C++) to do this question:

Create a new project called Lab05b. Keep the main file named main.

• Write a function readAndPrint, and power with parameters noted below in the Functions.h file.

//Your Last Name

#ifndef FUNCTIONS_H

#define FUNCTIONS_H

#include <fstream>

#include <iostream>

#include <string>

using namespace std;

/*reads from a file

and prints every item to the screen*/

// file contains sets of

//int

//string

//Don't forget to use infile.ignore() between << and getline

//ifstream must be passed by reference

void readAndPrint(ifstream &infile);

//uses a for loop to return the base to the exponent

//e.g. 2^4 = 16

// this fuction should read data.txt file

long power(long base, long exponent);

#endif

• You should place the function prototypes in a file called Functions.h The function prototype has a semi-colon at the end.

• Then you should implement in a file called Functions.cpp

• Finally, declare the infile, and call the readAndPrint function. Then look at the power of 2^3 and 10 ^ 4

• Create a file named data.txt that has the following information.

1

Alpha

2

Beta

3

Gamma

• Your functions.cpp AND your lastnamefirstLab05b.cpp should #include “Functions.h”.

• Remember that you should not #include.cpp files!

• Implementation detail 4: compile and run with:

Run your code

Please take screenshots of Lab05b.cpp, Functions.h, and Functions.cpp.

Thanks for your help!

If you have any doubts, please give me comment...

Functions.h

#ifndef FUNCTIONS_H

#define FUNCTIONS_H

#include <fstream>

#include <iostream>

#include <string>

using namespace std;

/*reads from a file

and prints every item to the screen*/

// file contains sets of

//int

//string

//Don't forget to use infile.ignore() between << and getline

//ifstream must be passed by reference

void readAndPrint(ifstream &infile);

//uses a for loop to return the base to the exponent

//e.g. 2^4 = 16

// this fuction should read data.txt file

long power(long base, long exponent);

#endif

Functions.cpp

#include "Functions.h"

void readAndPrint(ifstream &infile){

    infile.open("data.txt");

    int num;

    string str;

    while(!infile.eof()){

        infile>>num;

        infile.ignore();

        getline(infile, str);

        cout<<num<<endl;

        cout<<str<<endl;

    }

    infile.close();

}

long power(long base, long exponent){

    int result = 1;

    for(int i=0; i<exponent; i++){

        result *= base;

    }

    return result;

}

Lab05b.cpp

#include<iostream>

#include "Functions.h"

int main(){

    ifstream infile;

    readAndPrint(infile);

    cout<<endl;

    cout<<"2^3 = "<<power(2, 3)<<endl;

    cout<<"10^4 = "<<power(10, 4)<<endl;

    return 0;

}
