Thread: Too few arguments to function - Trouble with functions

I am trying to create a program that will take a number you give to the input and then it will check through my calc() function what number it is then prints it out as a string from the integer you gave it. I am new to this so can anyone help me with my code?

Error: Too few arguments to function

p.s Tip would be greatly appreciated. I am not sure if I am doing my functions correctly

Code:

#include <iostream>

using namespace std;
// Function prototype
int zero(int x);
int one_through_nine(int x);
int tenUp(int x);
int twenties(int x);
int calc(int x);

int main()
{
    // Take input
    int result;
    cout << "Enter number: " << endl;
    cin >> result;

    // Run input through calc function
    cout << calc(result);
    return 0;
}


// Returns 0
int zero(int x){
    if(x < 1){
        cout << "zero";
    }
    return x;
}

// Returns 1 - 9
int one_through_nine(int x){
    if(x == 1){
        cout << "one";
    }else if(x == 2){
        cout << "two";
    }else if(x == 3){
        cout << "three";
    }else if(x == 4){
        cout << "four";
    }else if(x == 5){
        cout << "five";
    }else if(x == 6){
        cout << "six";
    }else if(x == 7){
        cout << "seven";
    }else if(x == 8){
        cout << "eight";
    }else if(x == 9){
        cout << "nine";
    }
    return x;
}

// Returns 10 - 20
int tenUp(int x){
    if(x == 10){
        cout << "ten";
    }else if(x == 11){
        cout << "eleven";
    }else if(x == 12){
        cout << "twelve";
    }else if(x == 13){
        cout << "thirteen";
    }else if(x == 14){
        cout << "fourteen";
    }else if(x == 15){
        cout << "fifteen";
    }else if(x == 16){
        cout << "sixteen";
    }else if(x == 17){
        cout << "seventeen";
    }else if(x == 18){
        cout << "eighteen";
    }else if(x == 19){
        cout << "eleven";
    }
    return x;
}

// Returns numbers 20 - 29
int twenties(int x){
    if(x == 20){
        cout << "twenty";
    }else if(x < 30){
        cout << "twenty -" << one_through_nine();
    }
    return x;
}

// Calculates what function x will be put through
int calc(int x){
    if(x == 0){
        cout << zero(x);
    } else if(x < 10){
        cout << one_through_nine(x);
    }else if(x < 20){
        cout << tenUp(x);
    }else if (x < 30){
        cout << twenties(x);
    }else{
        cout << "Numbers are under construction.\nSorry for the inconvenience." << endl;
        return x;
    }
    return x;
}

Thank you very much for your help guys

I had changed up my twenties function to a twntUp so I can just go through the rest of the ten digits until I hit 100. I also added a x -= 20; to the same function so it can just add one-nine when it hits over 20.

but now I am having an issue that after it prints what I was looking for it gives me 3 to 2 0's after my output. I am wondering if it is my program or my cmd line.

My command line keeps acting funky if I do a loop up to 100, it will only show me from 98 or 97 and sometimes 73 does the command line usually do things like that?

Grumpy: "Overall: an unnecessarily contorted way to print out integral values as words."
Should I be doing loops instead or switch statements?

Code:

#include <iostream>

using namespace std;
// Function prototype
int zero(int x);
int one_through_nine(int x);
int tenUp(int x);
int twntUp(int x);
int calc(int x);

int main()
{
    // Take input
    int result;
    cout << "Enter number: " << endl;
    cin >> result;

    // Run input through calc function
    cout << calc(result);
    return 0;
}
