    Unhappy Double skull(6's) dice game. Need help T-T

    hey guys, the program im going to post up is my homework assignment that was due last week. I have tried so many times to work this thing out, even went in for tutoring but still cant get the program to run; so ive decided to get some real help. Here are the specific details:

    -MIN_BET MAX_BET and START_AMOUNT are #defined as 5, 50, and 200 respectively.
    **if the call to the input function doesnt return 0, do the following:
    -call a function to play double skull
    -call a function to add or subtract the users money depending on the results.
    -call a function to print the results of the betting.
    repeat to**

    -in the input function prompt for a bet(display what the users money is in prompt. if bet<MIN_BET or MAX_BET or >usersMoney and not 0 nor usersMoney<MIN_BET, print an error message and read bet again. loop until bet is 0 or between MIN_BET and MAX_BET.
    -in the same function, prompt if the user wants to bet for the computer to get double 6's within 25 rolls or not. return the bet in a return statement or 0 if the usersMoney<MINBET.
    - in the function to play the game. get 2 random numbers using random function in a loop until its executed 25 times. if the computer rolled double 6's. print a message stating that it rolled double 6's and display how many rolls were made, then return true. if it didnt within 25 rolls, print a message and return false.
    - in the function to add or subtract users money, determine to add or subtract the money base on the bet.
    - in the function that prints the results, print if the user won the bet or not. how much he/she won or lost, and how much money is left.
    -use while loop, do-while loop, for loop, if statements.

    *** with that said. what i have finished within the past week will be posted below. I dont want a straight up answer for my program, that would be cheating. i just hope you guys can give me some tips as to where to fix my functions and what to fix them to; an explanation would be nice too. this is a beginning c class, and the programs are driving me nuts. Thanks in advance for any tips, i greatly appreciate it.

    Compilations results, seeing as you couldn't be bothered to provide them:
    Code:
    gcc -ggdb3 -Wall -pedantic -o queef queef.c
    queef.c:8: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘getInput’
    queef.c: In function ‘main’:
    queef.c:15: error: expected declaration specifiers or ‘...’ before numeric constant
    queef.c:16: error: expected declaration specifiers or ‘...’ before numeric constant
    queef.c:17: error: expected declaration specifiers or ‘...’ before numeric constant
    queef.c:21: warning: implicit declaration of function ‘getInput’
    queef.c:24: warning: passing argument 3 of ‘printOutput’ makes integer from pointer without a cast
    queef.c:24: warning: passing argument 4 of ‘printOutput’ makes integer from pointer without a cast
    queef.c:19: warning: unused variable ‘betRoll’
    queef.c: At top level:
    queef.c:30: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘getInput’
    queef.c: In function ‘randDice’:
    queef.c:67: warning: format ‘%d’ expects type ‘int’, but argument 3 has type ‘int *’
    queef.c:67: warning: format ‘%d’ expects type ‘int’, but argument 4 has type ‘int *’
    Code:
    queef.c:8: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘getInput’
    bool is not a standard C datatype; you would need to #include <stdbool.h>

    Code:
    queef.c:15: error: expected declaration specifiers or ‘...’ before numeric constant
    queef.c:16: error: expected declaration specifiers or ‘...’ before numeric constant
    queef.c:17: error: expected declaration specifiers or ‘...’ before numeric constant
    Code:
    int inBet(0);
    int userBet(0);
    double userMoney(0);
    You can initialize variables that way in C++, not C. Use = 0.

    Code:
    queef.c:20: warning: unused variable ‘betRoll’
    Self-explanatory

    Code:
    queef.c:45: warning: format ‘%d’ expects type ‘int *’, but argument 2 has type ‘int **’
    queef.c:49: warning: format ‘%d’ expects type ‘int *’, but argument 2 has type ‘int **’
    queef.c:52: warning: format ‘%d’ expects type ‘int *’, but argument 2 has type ‘int **’
    pinBet and pbetRoll are already pointers, so you do not need to use the & in your scanf calls.

    Code:
    queef.c: In function ‘randDice’:
    queef.c:68: warning: format ‘%d’ expects type ‘int’, but argument 3 has type ‘int *’
    queef.c:68: warning: format ‘%d’ expects type ‘int’, but argument 4 has type ‘int *’
    The opposite of the above. pdice1 and pdice2 are pointers, so you need to dereference them like you did elsewhere in the function before printf can use them properly.

    Code:
    void calcMoney(int *puserMoney, int *pinBet)
    {
        int betRoll;
        int dice1;
        int dice2;
        if(betRoll!=0&&(dice1!=6&&dice2!=6))
    You did not initialize betRoll, dice1 or dice2 here, so who knows what they contain.
