I am new to C++. Can somebody help me to learn different features of C++, like
a good tutorial or something. the best program i can make yet is this:
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
cout<<" Welcome to CBot- Your utlimate guide to doing any calcutaion of two
numbers! "<< " \n Please click enter to continue ";
int a,b,c,min,max,cal,com,ent;
getch();
start:
clrscr();
cout<<" Please enter the first number ";
cin>> a;
clrscr();
cout<<" Please enter the second number ";
cin>> b;
clrscr();
cout<<" You entered "<< a<< " and " <<b;
cout<<" \n Please confirm these numbers.Press 1 if the numbers are right
and press 2 if the numbers are wrong and you wish to re-enter the numbers ";
cin>>com;
if (com==1)
{
cout<<" You confirmed the numbers. please click enter to see the
calculation options ";
getch();
clrscr();
cout<<" ADD-1 ";
cout<<"\n SUBTRACT-2 ";
cout<<"\n DIVIDE-3 ";
cout<<"\n MULTIPLY-4 ";
cout<<"\n MAXIMUM-5 ";
cout<<"\n MINIMUM-6 ";
cout<<"\n Please enter the number corresponsing to the calculation you
would like to do ";
cin>>cal;
if ( cal==1)
{
cout<<" The sum of "<< a<<" and "<<b<<" is "<<a+b;
}
if ( cal==2)
{
cout<<" The remainder of "<< a<<" and "<<b<<" is "<<a-b;
}
if ( cal==3)
{
cout<<" The divident of "<< a<<" and "<<b<<" is "<<a/b;
}
if ( cal==4)
{
cout<<" The product of "<< a<<" and "<<b<<" is "<<a*b;
}
if ( cal==6)
{
min=a;
if (min>b)
{
min=b;
}
cout<<" the smaller number between "<<a<<" and "<<b<<" is "<<
min;
}
if ( cal==5)
{
max=a;
if (max<b)
{
max=b;
}
cout<<" the bigger number between "<<a<<" and "<<b<<" is "<<
max;
}
}
if (com==2)
{
cout<<" Please press enter to try again ";
getch();
goto start;
}
cout<<endl<<"\n Hope you enjoyed the program. Press 1 to do another
calculation. Press 2 to exit the program ";
cin>>ent;
if (ent==1)
{
goto start;
}
if (ent==2)
{
clrscr();
cout<<" Press enter to end the program ";
getch();
}
}
Guys, please make me aware of more things on C++. THanks

There isn't anything in the C Standard - I suspect C++ is the same, although
I'm not a C++ programmer.
Try checking your compiler/IDE documentation - there might be an option that
adds some sort of checking to the generated code.

The OS might allocate memory in blocks, and the smallest block might be (for
example) 1k. It might not be the most space efficient algorithm, but it might
be quicker and simpler than one that allocates exactly the amount you request.
If you are interested, try Googling for 'memory allocation' eg.
http://en.wikipedia .org/wiki/ Dynamic_memory_ allocation
