C++ code for Scramble game using filing and C++ basics (with algorithm)

Here is the C++ code for Scramble game . This game includes multiple levels and each level gives you score . You all should have in mind how it works exactly. Here is the algorithm.

  Steps

User side

1: User showed with a Scrambled word and asked to enter correct one.

2: If user enters correct word levels up and score increased by 100
3: If user enters wrong word , this game gives another chance
4: If user enters correct word , levels up and score increased by 70
5: If user enters wrong word , this game gives another chance
6: If user enters correct word , levels up and score increased by 40
5: If user enters wrong word , the game ends here

Developer side

1: Declare variables that are going to be used in program (three character arrays one to store  Scrambled word one to store  correct word and another one for input )

2: Open scrambled word file "scramble word.txt" using following statement in.open("scramble word.txt");

3: Open correct word file "correct.txt" using following statement  inc.open("correct.txt");

4: Start a while loop at the end of any file (because both file are of same size)

5: Here read scrambled and correct word from respective files
6: Show scrambled word

7: Call enterguess(); function to input user's guess
8: Compare input with  correct word
9: If user enters correct word levels up and score increased by 100
10: If user enters wrong word , this game gives another chance
11: If user enters correct word , levels up and score increased by 70
12: If user enters wrong word , this game gives another chance
13: If user enters correct word , levels up and score increased by 40
14: If user enters wrong word , the game ends here

Code:

#include<iostream>

#include<fstream>

using namespace std;

int level=1,score=0;

int i=0,cal=0,c=0;

ifstream in,inc;

char ch[50],input[50],chc[50];

void enterguess();

int main()

{

       int firstcase=0;

       in.open("scramble word.txt");

       inc.open("correct.txt");

       while(!in.eof())

       {      system("CLS");

             

       if(level%2==0)

       {system("color a");}

       else {system("color 4");}

              cout<<"\t\tLevel : "<<level<<"\t\tScore : "<<score<<endl;

              i=0;cal=0;c=0;

              //Read scrambled word

              for(;i<50;i++)

              {in>>ch[i];

              if(ch[i]==','){break;}

              cout<<ch[i];

              }

              // Read corret word

              for(;c<50;c++)

              {inc>>chc[c];

              if(chc[c]==','){break;}

              }

              enterguess();

              if(firstcase==0)

              {i=i-1; firstcase=1;}

              if(cal==i)

              {cout<<"You entered right"<<endl; score=score+100;system("pause");}

              else

              {      cout<<"wrong! Try again"<<endl;

                           enterguess();

                           if(cal==i)

                           {cout<<"You entered right"<<endl;score=score+70;system("pause");}

                           else

                                  {      cout<<"wrong! Try again"<<endl;

                                                enterguess();

                                                if(cal==i)

                                                       {cout<<"You entered right"<<endl;score=score+40;system("pause");}

                                                else {cout<<"Game is over! And your score is : "<<score<<endl;break;}

                                 

                                  }

              }

              if(level==100)

       {cout<<"You won the game and your score is"<<score<<endl;break;}

              level=level+1;

             

       }

       in.close();

       inc.close();

       system("pause");

       return 0;

}

void enterguess()

{      cal=0;

       cout<<endl<<"Enter your guess";

              for(int a=0;a<i;a++)

              {cin>>input[a];}

              cin.ignore();

              //comparison

              for(int a=0;a<i;a++)

              {if(chc[a]==input[a])

                     {cal=cal+1;}

              }

      

}
