hey guys here are some of my c++ projects after 2 days of learning......i got amost all of it from a tutorial and stuff but i actually know wat it means and stuff now.......this is here just to prove that ppl like me who always used to leech stuff are actually trying to learn now...i am NOT going to give up and just take a look at it before this topic gets moved 
i know this is pure randomness so meh w/e deal w/ it
| Code: | #include<iostream>
using namespace std;
int main()
{
cout << "This is my program " << endl;
system("pause");
return 0;
} |
and a longer one
| Code: | #include<iostream>
using namespace std;
int main(void)
{
system("TITLE Travis' Calculator");
system("COLOR 4F");
char cChar;
double dfirstnumber;
double dsecondnumber;
char cDoagain;
do
{
system("CLS");
cout << "please enter the first number that you would like to use" << endl;
cin >> dfirstnumber;
cout << "please enter the operation that you would like to complete" << " (+,-,* or /)" << endl;
cin >> cChar;
cout << "please enter the second number you would like to use" << endl;
cin >> dsecondnumber;
switch (cChar)
{
case '+':
cout << "The answer is: " << dfirstnumber << " + " << dsecondnumber << " = " << (dfirstnumber + dsecondnumber) << endl;
break;
case '-':
cout << "The answer is: " << dfirstnumber << " - " << dsecondnumber << " = " << (dfirstnumber - dsecondnumber) << endl;
break;
case '*':
cout << "The answer is: " << dfirstnumber << " * " << dsecondnumber << " = " << (dfirstnumber * dsecondnumber) << endl;
break;
case 'x':
cout << "The answer is: " << dfirstnumber << " x " << dsecondnumber << " = " << (dfirstnumber * dsecondnumber) << endl;
break;
case 'X':
cout << "The answer is: " << dfirstnumber << " X " << dsecondnumber << " = " << (dfirstnumber * dsecondnumber) << endl;
break;
case '/':
if(dsecondnumber == 0){
cout << "That is an invalid operation" << endl;
}else{
cout << "The answer is: " << dfirstnumber << " + " << dsecondnumber << " = " << (dfirstnumber + dsecondnumber) << endl;
}
break;
default:
cout << "That is an invalid operation" << endl;
break;
}
cout << "Would you like to start again? (y or n)" << endl;
cin >> cDoagain;
}while (cDoagain == 'Y' || cDoagain == 'y');
system ("PAUSE");
return 0;

Have you tried to compile this?
Borland gives two errors :
1. Line 2 - Namespace name expected
2. Line 7 - Call to undefined function 'system' in function main()
Now fix it! 
And keep up the good work.
C++ wins.

lol thanks for replying....and yes i have compiled it with dev-c++............GREAT program i like it lots, i would use visual c++ from microsoft but my computer gets an error trying to install .net 3.5 framework (NO CLUE WHY IF U KNOW WHY TELL ME ANYONE  )
anyways yeah i got no errors...after fixing it a million times and its in an exe now and it works great
btw ppl if u need good tutorials on learning c++ heres a good guy on youtube that gives good tutorials.....DONT RUSH THROUGH THEM....understand EVERYTHING before u go on to video 2 et cetra.

Okay, might be slight differences between the compilers.
I used to use dev-cpp. Nice program.
Edit: Their site is this?

You've got me there. I've only really worked in depth with C++. I like controlling everything in my programs. 
So, I'm not really sure. You'd probably have to start getting into Delphi more to figure out how.

well yeah if i ever wanted to release something i would want to write it in c++ but i would like some kind of design to it, not just a black box or maybe change the colour of foreground and backround.....meh ill search around
p.s. trade rep?

| I wouldn't use anything from system...I remember when I was learning the basics people were scolded for using that...especially to just pause the program from shutting off. Use cin.ignore() and cin.get().

Heya, im learning C++ too! Compile this! fully commented and stuff, not complete yet. Gotta finish the math part of it.
| Code: | #include <iostream>
using namespace std;
int goal, current, buy, sell;//declaring integers for use
int profitper, profit, d, e, f; //integers used in the math part
int itemsper;
int remainder;//these integers will be thrown away later, just needed to store temporary values
int main(){//main part of program
cout<<"Enter current money available for merchenting: ";
cin>>current;//gets current money for merchenting. Cout stands for console (keyboard) out. Cin stands for console in.
cin.ignore();//ignores enter, so cin.get doesn't trigger.
cout<<"Enter goal for total cash at end of merchenting: ";
cin>>goal;//Gets Goal for cash
cin.get();
sorry4screweingGoodPractice://C++ "joke"
cout<<"How much are you buying the item for: ";
cin>>buy;//gets how much to buy item for
cin.get();
cout<<"How much are you going to sell the item for: ";
cin>>sell;
cin.ignore();
if(buy>sell){
goto sorry4screweingGoodPractice;
}
while (current<goal);{//while current money is less than goal do this
profitper=sell-buy;//gets profit per item
itemsper=current/buy;
remainder=current%buy;//the "%" operator returns the remainder of the divisor
if(remainder){
current=current+1;
}
profit=profitper*itemsper;
cout<<"lol";
}
cout<<"Test";
cin.get();//when finished, press enter to terminate program
}

I just hope you stay dedicated(after 2 days), we need more C++ coders.

| Coding GUIs eh.. well that will be in the far future. Focus now on pointers/arrays/classes/objects and master those completely on console apps. Then start to learn the Windows API and how to code GUIs from there. I know its tempting to build a bot, we all feel it, but its much better when you code it efficiently and when you know EVERYTHING about what you are doing.

Not bad practice if you use it right.
