Hangman program

[Eyecon]

I am trying to make a hangman program to practice i made the following and it runs without errors but it doesnt what its supposed to do i get some weird text instead :
Untitled(537) malloc: *** error for object 0x100006280: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Program received signal: “SIGABRT”.
sharedlibrary apply-load-rules all

#include <iostream>
using namespace std;

int lives(int x,int y)
{

	if (y=1) {
	
	x=x-1;
	}

	return x;
	

}

int main (int argc, char * const argv[]) {
    
	/* Hmm i am thinking of a new program. I could fix something... entertaining maybe. */ 
	
	/*Hangman */
	
	
	
		int i,u,y,x,o;
	
	

	x=4;
	
	
	string word; //the word we will be looking for
	cin >> word;
	word.size();
	char solution[word.size()]; // the word we are going to build
	
	for (i=0; i<=word.size(); i++) {
		solution[i]='-';
	}
	
	
	// User starts to input Chars
	
	char a;
	cin >> a;
	
	if (lives(x,y)>0) {
		
		
	for(i=0;i<=word.size();i++){
		
		
		if (word[i]==a) {
			
			solution[i]=a;}
		
			else {
				y=1;
				o=lives(x,y);
				cout << o << "lives remaining"; // function for lives
				
			}

		}
		cin>>a;
	}
	
		

	
	else{
		cout << "GAME OVER";
		}
	

	
	
	
	for (i=0; i<=word.size(); i++) {
		cout << " "<<solution[i] << endl;
		cout << " _";
	}
	
	
    return 0;
}

It looks like you have a problem with every one of your "for" loops. You should compare i < word.size(), as solution[ word.size() ] is an invalid address.

Also, in your lives function, did you mean to assign 1 to y or compare it? If you want to compare it, use ==.

fixed what you told me but still have same problem when running

This is the GDB debugger, and it is attaching to process 799. Is that the process id of your program?
