Question

Description: The search method should prompt the user for a search phrase. Given the search phrase the search method should search each line in the file for the location of the phrase on each line. If the search phrase is not found on a line then just go to the next line. The search method must find every occurrence of the phrase on a line. The search method should print the line number, the line and the location of the search phrase (“use ^”). After all lines have been searched the search method then prompts the user to enter another search phrase. The search method does not exit until the user enters the phrase EINPUT. See Sample Outputi.

#include <iostream>
#include <fstream>
#include <cstdio>
#include <cstdlib>
#include <cstring>
using namespace std;

// main function definition
int main()
{
// To store the word to search
char wordToSearch[256];

// Opens the file

// Checks if file is unable to open then displays error message

exit(0);
}// End of if condition

// To store the line number
int lineNumber = 0;

// Accepts a word to search
cout<<"Enter the word you want to search for (EINPUT to stop): ";
cin>>wordToSearch;

// Checks if user entered word is equals to "EINPUT" then stop

// Loops till end of the file

Sample Output:

Enter the word you want to search for (EINPUT to stop): does

does found on line: 3

Enter the word you want to search for (EINPUT to stop): found

Not found.
Enter the word you want to search for (EINPUT to stop): because

because found on line: 3

Enter the word you want to search for (EINPUT to stop): EINPUT

searchPhrase.txt file contents

For God so loved the world that the gave this one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him.
Whoever believes in him is not condemned but whoever does not believe stands condemned already because they have not believed in the name of God's one and only Son.

This is the verdict: Light has come into the world, but people loved darkness instead of light because their deeds were evil.
Everyone who does evil hates the light, and will not come into the light for fear that their deeds will be exposed.
But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God."
