engch_cpp

methods that I edited/found useful and want to keep for easy reusing

How to use:

#include "Library.h"
using namespace Engch;
Library ec;

void Library::changeCmdTextColor(int colorChoice)

highlight the next character onwards with colorChoice in cmd
7 is default color

// example 
printf("[");
ec.changeCmdTextColor(hConsole, 10); 
printf("%c", 'x'); // highlighted char
ec.changeCmdTextColor(hConsole, 7); // reset color back to default
printf("]");

double Library::getRand(double range)

return a random double from 0 to range

double Library::getDoubleModulus(double x, double y)

double modulus double, w/floating number point error
return x mod y in double.

bool Library::isDoneBefore()

used in if condition to run only once
return true is not run before, false if run before

// example --> no yes yes
std::string e = "no";
printf("%s\n", e.c_str()); // no

if (ec.isDoneBefore()){
    e = "yes";
}
printf("%s\n", e.c_str()); // yes

if (ec.isDoneBefore()){ // never enter as it ran before already
    e = "no";
}
printf("%s\n", e.c_str()); // yes
