Question

C++
Demonstrate an understanding of array processing.

Write a function that accepts the name of a file (by asking the user), an array of strings, and the size of the array. Display each character of each string vertically to the file. For example, if the array is called with an array of 3 strings “hello”, “abc”, “bye”, the output will be:

h

e

l

l

o

….

y

e

Test the function with a string declaration of: string name[] = {"hello", "abc", "bye"};

Answer 1

#include <iostream>

#include <fstream>

using namespace std;

void writeToFile(string fname, string a[], int n)

{

ofstream mf; // declaring variables

mf.open (fname);

for(int i=0; i<n; i++) // looping for n times

{

for(int j=0; j<a[i].length(); j++) // taking each char

mf << a[i][j] << endl; // writing to file in a line

}

mf.close(); // closing

}

int main() {

// declaring variables

string fname;

int n;

string name[] = {"hello", "abc", "bye"};

cout << "Enter name of the file: ";

cin >> fname;

writeToFile(fname, name, 3);

}

/*OUTPUT
