Now, you really need to stop using C standard functions, like printf and scanf. The C++ equivalents make the code easier to read and are *just as well implemented* in the STL (standard template library). C code will normally compile because C++ is a superset of C and some software, e.g. win32, hasn't been fully converted to C++ yet.

Next, as mentioned above, system("pause") doesn't work outside dos/windows. If your programme just runs and exits without you being able to see the output try my v2. It seems you are very new to programming overall - no worries and well done for giving it a go.

Amongst other paradigms, Encapsulation and Abstraction are part of the bedrock of C++, as an OO language. In programming, encapsulation means wrapping functionality together. And, abstraction means removing or separating one bit of functionality from another.

I will edit this post in a minute with the C++ version of your code.

ps - any chance you can either start a new thread or remove the Solved if you've got more questions. Bit misleading otherwise.

One more qustion
#include <iostream>


int main()
{
int s; //salry

printf("enter your salary");
scanf ("%d",&s);
if (s>=1000)
{
if (s>=3000)
{
if (s>=5000)
printf ("your bonus is 500");

else
printf("your bonus is300");
}
else
printf("your bonus is100");
}
else
printf("no bonus");
system("PAUSE");
}

i have been told to learn C before starting c++ to learn basics of codes etc
