Question

in basic c++ program please!!

Write a word search and word count program.

1. Assign the following text to a string constant.

For God so loved the world that he gave his 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. ²¹ 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.

2. Prompt the user to enter a word or phrase
3. Search the string given by the user from the text above and inform how many times the word/phrase was found in the text.

(Hint: You need to use while loop, .find and .length function from string library. Also, you will need to use string::npos.)

1. Your SOURCE CODE (.cpp file ONLY, such as main.cpp, filename.cpp. It is NOT .sln or any other extensions)
2. Search for the following (ALL strings are CASE-SENSITIVE!)
   1. God
   2. the world
   3. believe
   4. Jesus
   5. only Son
   6. life

  

Answer 1

C++ code:

#include <iostream>
#include <string>
using namespace std;

int main()
{
//String from which the words will be searched
   string str = "For God so loved the world that he gave his 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. \
   21 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.";

   cout<<"Enter String or phrase to be searched:\n";

   string c;

   //Taking word/phrase from user
   getline(cin,c);

   //Finding the index of word/phrase in the string
size_t found = str.find(c);
int count=0;

//Loop till reaches end of the string
while (found != string::npos){
count++;
  
//Finding word/phrase from next index of the previous occurrence of it.
found = str.find(c, found+1);
}

cout<<"The word/phrase "<<c<< " comes "<<count<<" times."<<"\n";
return 0;
}

Output:
