I've been learning C++ for over 2 months now on my own.... but i have run out of idea's for new programs
can anyone give me a challange not something TOO hard since i am still quite new to the language but a little challenge would be great
Thank You

how about checkers. Or even simpler, tic-tac-toe. You can make the computer play against you.
I think that tic tac toe is a good idea. I did one last year.
First of all, wow, I can't believe you ran out of ideas. I only wish that I could have the time to code out all of my ideas.Quote:

Here are some possibilities:
Write a calculator that allows the user to input something like "3+4*2" and outputs 11(notice the order of operations there).
Output Parkside's triangle given a seed and a size.
Write a program that encrypts and decrypts messages using various ciphers (my teacher suggested that one for me).
Think of any card game you have ever played. Then, code it.
You also might want to do some googling for programming challenges and problems used for competitions.
thank you all very much!!
One question...
I also have an idea of making some sort of game editor for an online game.... but what it needs to do accept input from the Clipboard when someone copies information about there stats, gold etc
How would i be able to do that.
And about the calculator... it seems pretty simple apart form that i don't know how to strip strings from sertian characters.
Can anybody help... give me some sort of example a really simple one like where you input name and age in one big line without spaces and it splits/strips them apart.
Thank you again
Remember that strings are arrays of characters.Quote:

Now use that method to search through a string like "1+2" looking for +,-,*,/. You can use the library <ctype> for functions to determine if a character is a letter or a number or several other things.Code:int j = 0;
char str2[MAX];
char str1[MAX]= "Hello World!";
// str1[0] == 'H';
for(int i = 0; (str1[i] != ' ') ||(str1[i] != '\0'); ++i)
{
str2[j] = str1[i];
++j
}
// str2 == "Hello";
If you limit your calculator to single digit numbers and have a good grasp on arrays, it shouldn't be too difficult.
Thanks... but is '*' is this a .... well what kind of character is it??
from this my best guess would be: int iscntrl(int);Code://taken from ctype.h
int isalnum(int);
int isalpha(int);
int iscntrl(int);
int isdigit(int);
int isgraph(int);
int islower(int);
int isprint(int);
int ispunct(int);
int isspace(int);
int isupper(int);
int isxdigit(int);
but i'm probally wrong
My guess would be ispunct, but I could easily be wrong. To be sure, you could write a program to find out which one of those categories it fits into. What I suggest is writing your own function. That wouldn't be hard at all. Just look at an ASCII table to find the integer values for +,-,*, and /. Then write a function that returns true if the character is one of those characters and false otherwise.Quote:

Hope that helps.
I got one
I like it:::
Create an Abstract Data type called
newInt
that is basically the same as an int except it has new properties
it also has an array for its factors
it has a boolean function iseven()
and it has all the necessary overloaded operators +,-,+=,-=,=,<,<=,>,>= etc.
and it overloads the ostream and istream operators.
it is also a templated class ex:
oh and it stores the VALUE in two waysCode:template<class T>
class newInt
{
public:
newInt();
newInt(T target);
//Memberfunctions etc.
//Overloaded operators
private:
//the way your going to store all this info
};
//Overloaded Stream operators
one in just a complete int value and another in an array digit-by-digit
have fun!
btw: I have this done if anyone cares
in 2 days, I will show the DECLERATIONS

???
ok... hmmm... I've no clue...
Explain that to me please I haven't learned Templates yet.
well here is the outcome:
that is the claculator if you haven't noticed. I know it sucks. Any suggestions??Code:#include <iostream.h>
#include <conio.h>
#include <stdlib.h>
int main()
{
char num[20]= { 0 };
double temp;
char next;
int x = 0;
int y = 0;
cout<<"Calc: ";
cin>>num;
for(int i=0;i<20;i++)
{
if(num[i] == '*')
{
x = i-1;
y = i+1;
temp = atof(&num[x])*atof(&num[y]);
}
if(num[i] == '/')
{
x = i-1;
y = i+1;
temp = atof(&num[x])/atof(&num[y]);
}
if(num[i] == '+')
{
x = i-1;
y = i+1;
temp = atof(&num[x])+atof(&num[y]);
}
if(num[i] == '-')
{
x = i-1;
y = i+1;
temp = atof(&num[x])-atof(&num[y]);
}
}
cout<<"\n"<<temp;
getchar();
return 0;
}
This isn't exactly a place that templating makes any sense considering there are no datatypes/values that would be templated in your description and example overview.Quote:
