1. Please use [code]//code goes here [/code] tags.
2. Please read http://www.cplusplus.com/forum/beginner/1/ . Basically we need detailed information, including a verbatim of the error messages. Don't make us guess what the errors are: Tell us.

Lines 38 to 49 (in this post) are outside a function. They need to be inside a function.

In line 68, you try to use a variable called "userguess" that you did not define.

I suppose that line 76 is meant to be a comment line??? Same for line 78 and 82.

How about this?

 

//Guesses letter game

#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>
#include <ctype.h>

#define MAX_GUESSES 6

//function prototypes
	int i;
	int numberofgames;
	char ans;
	char getguess;
	int compareguess(char guess, char ans);

int main()
{
	FILE* infile;
	//int i;
	//int numberofgames;
	//char ans;
	//char getguess;
	//int compareguess(char guess, char ans);
	printf("Please enter the no of games you want to play");
	scanf("%d",& numberofgames);
	//variable declarations
	//prompt + get numgames
	//file pointer declaration	
	//display instructions on how to play the game
	printf("Enter an letter in the range a to z\n");
	printf("I will try to guess your letter with in 6 guesses\n");
	printf("If you can guess my letter in 6 guesses, You Win!\n");
    printf("Would you like to play?\n");
    printf("Press 'Y' to play, or 'N' to quit\n");
    printf("Char Playgame\n");

	//connect to the file

	return 0;
}
	for(i=1; i<=numberofgames; i++)
	{
		//print current game (value of i)
		//get letter to guess from fscanf
		fscanf(infile," %c",&ans);
		//printf to check the letters from file

	int playgame (char ans); 
	{
		char guess;
		numberofguess=0, win or lose=0;
		//call the play function to play a game
		numberofgames=playgame (ans);
		//it will return a 1 if the user wins and a 0 if the user took more than 6 guesses
		//condition here to print win or lose
		numberofgames==0'lose';
		numberofgames==1'win';
	}
	return 0;
}

All the errors deal with the line of the for function:
(42): error C2059: syntax error : 'for'
(42): error C2143: syntax error : missing '{' before '<='
(42): error C2059: syntax error : '<='

(42): error C2059: syntax error : '++'
(42): error C2059: syntax error : ')'

Lines 44 to 50 do not belong to the function main() or any other function. They need to belong to a function.

Line 53 is not doing anything. Line 55 produces recursion but there's no condition to avoid a stack overflow. Lines 58 and 59 are not valid C++.

You are also missing the closing brace of the for loop in line 40. You open a brace in line 41 but you don't close it. This is one of the reasons to use proper indentation: To easily see where you are missing stuff like closing braces.

[xokelz04]

ok, can you help me word them the way they should be? Im completely new at this and still a bit lost

[webJose]

Well, I cannot fix playgame() if I don't know its purpose and intended return values. As it is right now, I think you want to use it to determine if the user won or lost. But you clearly have a lot of wrongs in the very basics of C++. I recommend that you study the basics before moving on to functions and the like.

For example, it seems that you want to return 0 or 1, but you always return 0 (see line 61).

[xokelz04]

yes i believe i do want to do that. This is all play game is: //this function runs one game. It for checks either 6 incorrect guesses or correct guess.
//It returns a 0 if the game is over and the player did not guess the letter, otherwise it returns 1.
int PlayGame(char answer);
