C Boolean Value

What this is

This project is an attempt to bring 'true' and 'false' values to the (GCC) C Programming language. This project may work in C++, but no testing has been done.

Motivations

One of the major factors preventing newer programmers from adopting C is its lack of similarity with higher level languages and constructs. The most noticable difference between C and these more modern languages is likely its lack of reserved true and false values. By making this, I hope to draw more people to use the C Programming Language.

Features

True value
False value

Installing

This library can be installed a number of ways.

Git

git clone https://github.com/lduck11007/c-bool-value.git
cp c-bool-value/src/cboolvalue.h cboolvalue.h
rm -rf c-bool-value

Curl

curl https://raw.githubusercontent.com/lduck11007/c-bool-value/master/src/cboolvalue.h > cboolvalue.h

Windows CMD

Create a file labled get.bat with the following:

@Echo OFF
SetLocal EnableDelayedExpansion
Set Var=%1
Set Var=!Var:http://=!
Set Var=!Var:/=,!
Set Var=!Var:%%20=?!
Set Var=!Var: =?!
Call :LOOP !var!
Echo.Downloading: %1 to %~p0!FN!
powershell.exe -Command (new-object System.Net.WebClient).DownloadFile('%1','%~p0!FN!')
GoTo :EOF
:LOOP
If "%1"=="" GoTo :EOF
Set FN=%1
Set FN=!FN:?= !
Shift
GoTo :LOOP

In cmd in the same directory or with PATH configured, type

get https://raw.githubusercontent.com/lduck11007/c-bool-value/master/src/cboolvalue.h

Examples

A simple function that returns true or false depending on whether an item is in an array

#include "cboolvalue.h"

int search(char values[], int len, char searchfor){
    int search_at = 0;
    int search_res = false;
    while(search_at < len && search_res == false){
        if(values[search_at] == searchfor)
            search_res = true;
        else
            search_at += 1;
    }
    return search_res;
}

For power users and kernel hackers, this can be rewritten as follows for far easier readability.

#include "cboolvalue.h"
#define bool int                    //TODO: learn how typedef works

bool search(char values[], int len, char searchfor){
    int search_at = 0;
    bool search_res = false;
    while(search_at < len && search_res == false){
        if(values[search_at] == searchfor)
            search_res = true;
        else
            search_at += 1;
    }
    return search_res;
}

It's plain to see that this program is now far easier to read for a programmer of any skill level, and is practically self-documenting.

More examples

Simple function that returns whether an array is sorted or not, made instantly more easy to understand with true and false values.

#include "cboolvalue.h"
#define bool int
bool issorted(char array[], int len){
    bool sorted = true;
    int i;
    for(i = 0; i < len; ++i){
        if(array[i-1] > array[i])
            sorted = false;
    }
    return sorted;
}
