    Error count exceeds 100

    Hey all,

    I started creating my first C program to test my comprehension of the basics, but I'm running into over 100 syntax errors. I can't tell what I'm doing wrong. Here's the code:

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <iostream>
    #include <cmath.h>
    
    void mainmenu();
    int joke();
    int calculator();
    int addition();
    int subtraction();
    int multiplication();
    int division();
    int add ( int x, int y );
    int subtract ( int x, int y );
    int multiply ( int x, int y );
    int divide ( int x, int y );
    
    int main()
    {
        system ("cls");
        printf("Hello. Welcome to the program.\n");
        printf("Press any key to continue...\n");
        getchar();
        mainmenu();
    
    }
    
    void mainmenu()
    {
    
        int menu1choice;
    
        printf("Menu 1\n");
            printf("~~~~~~~~~~\n");
            printf("1. Tell me a joke.\n");
            printf("2. Perform a simple calculation.\n");
            printf("3. Move to Menu 2.\n");
            scanf("%d", &menu1choice);
            switch ( menu1choice ) {
            case 1:{
                joke();
                break;
                   }
            case 2:{
                calculator();
                break;
                   }
            }
        }
    }
    
    int joke()
    {
        system("cls");
        printf("How do you get holy water? \n");
        system("pause");
        printf("You boil the hell out of it. \n");
        system("pause");
        system("cls");
        mainmenu();
        
    }
    
    int calculator()
    {
        int calculatorchoice;
    
        system("cls");
        printf("What type of calculation would you like to make? \n");
        printf("1.  Addition \n");
        printf("2.  Subtraction \n");
        printf("3.  Multiplication \n");
        printf("4.  Division \n");
        scanf("%d", &calculatorchoice);
        switch ( calculatorchoice ){
            case 1:{
                addition();
                break;
                   }
            case 2:{
                subtraction();
                break;
                   }
            case 3:{
                multiplication();
                break;
                   }
            case 4:{
                division();
                break;
                   }
        }
    }
    
    int addition()
    {
        int x;
        int y;
    
        system("cls");
        printf("Please input two numbers to be added: ");
        scanf( "%d", &x );
        scanf( "%d", &y );
        printf( "The product of your two numbers is %d\n", add( x, y ) );
        getchar();
    
    }
    Any help is appreciated

    Remove this line as there is usually no sense in including a C++ header in a C program:
    Code:
    #include <iostream>
    Change this line:
    Code:
    #include <cmath.h>
    to:
    Code:
    #include <math.h>
    You may still have more syntax errors, but don't worry about the count: fix them one by one.

    In addition to that, you've got an extra "}" on mainmenu, all the calculating functions but addition aren't defined (and produce linker errors), and you're not returning anything from functions that are supposed to return ints.

    This compiles, but a good practice is to add a function, compile, debug, repeat. That way you don't run into 20 compiler errors. By the way, you had an extra
    Code:
    }  //made me put code tags around this -_-
    in your main menu. This is most often caused by poor indentation practices.

    EDIT: Memcpy, you beat me to that.

    * Proper indentation is encouraged for all programming languages.
    * It shows levels of nesting, nested if statements , for loops, etc.
    * Anyone reading your code can tell whats executing inside of what.
    * It shows scope. If everything is indented you know the scope of variables.
    * Easier to read.
    * Better programming sense.

    If, for some reason, I don't make any sense at all, it's highly likely that I've been up all night on some strange bender that isn't normal. I likely unarmed and far from dangerous. While I haven't been known to physically harm anyone or anything else, there have been unsubstantiated reports that I have driven others into both a hazy stupor as well as a blinding rage. Otherwise, I hope I helped.
