Can't Read Input File

Hello Everyone,
I am a new member in the forum. I had a question regarding a code. The code is not able to open the input file. Any help is appreciated.
thanks

Here is the code,
#include <iostream> #include <fstream> #include <cstring> #include <cstdlib> #include <iomanip> using namespace std; const int MAX_TRY = 8; const int WORDS_NUMBER = 2; // why wrod number?? const int MAX_SIZE = 14; //int point_earn = 0; ifstream infile; // stream input file variable declaration globally void initialize(char [],int); void readString(char [], int &); //void guess(char []); //void printSolution(char []); //void compareWord(char []); int main() { char correct_word[MAX_SIZE] ; char solution[MAX_SIZE]; char letter; int length; cout << " WELCEOME TO THE HANGMAN Game " << endl; cout << " You will be given up to " << MAX_TRY << " attempts to find a letter." << endl; cout << " You will get a chance to solve the word after each letter attempt.\n\n\n"; infile.open("Proj4_input.txt"); //input file opens if(!infile) //checks if input file can be read properly { cout << "Cannot open the file\n"; //if error in inputfile invokes to output this exit(1); } readString(correct_word, length); initialize(solution,length); cout << "The word is " << correct_word << endl; cout << "THe solution is " << solution<< endl; cout << "Enter a letter of your choice : "; cin >> letter; //guess(correct_word); //printSolution(correct_word); //compareWord(correct_word); infile.close(); //input file closed return 0; } void initialize(char guessed_word[MAX_SIZE],int length)//initialize SOLUTION to *'s and other global variables to 0 { int j; for(j = 0; j < length; j++) { guessed_word[j] = '*'; } for(j=length; j< MAX_SIZE;j++) guessed_word[j] = ' '; cout << guessed_word << endl; } void readString(char word[], int& length)// read each word from the input file ???? { length = 0; infile.getline(word,MAX_SIZE); length = strlen(word); } /* void guess(char solution[MAX_SIZE])//Read in guesses until the limit is reached or the word is guessed,display the partial solution to the user { int index; int j = 0; int wrong_guess = 0; char guess_letter; cout << "Enter the guessed letter : "; cin >> guess_letter; for(index = 0; index < MAX_SIZE; index++) { if (guess_letter == solution[index]) { j++; cout << "The letter " << guess_letter << "in the word presents " << j << "times\n"; cout << "The partial solution is " << solution <<endl; } else { cout << " Uff, Wrong guess!! Try again : "; while(wrong_guess < MAX_TRY) { wrong_guess = wrong_guess++; cout << "your wrong guess is " << wrong_guess << endl; } cin >> guess_letter; } } } void printSolution(char word_guessed[MAX_SIZE])//print the guessed word and the number of times the player has tried { int count; for(int k = 0; k < MAX_SIZE; k++) { cout << word_guessed[k] << endl; } for(count = 0; count < MAX_TRY; count++) cout <<"you have tried " << count << "times\n"; } void compareWord(char word_original[MAX_SIZE]) //It is a function. It returns TRUE if every element of SOLUTION is not a '*' { char word_guessed[MAX_SIZE]; if(strcmp(word_original, word_original) == 0) { cout << "Wrong!!! YOU HAVE LOST THIS ROUND!\n"; cout << " The original word was " << word_original << endl; } else { cout << "Congrats!!! YOU HAVE WON THIS ROUND!\n"; cout << "The word is " << word_original << endl; } } */
