C++ is a badly designed (small) extension to C. C also has many design flaws mainly because the language was designed by compiler writers (very experiensed asm coders).
Every good C programmer knows roughly what their compiler produces when they write a line of C-code and they know how to avoid major performance issues.
That kind of thing is not learned because of using asm or any other language.. You learn that by knowing your processor, and C language does not hide any hardware.
I always divide by eight like this:
adc_value >>= 3;
If I need to write 0xFF to memory location 0x45, I can say;
*((char*)0x45) = 0xFF;
Ugly, yes, but very common thing with microcontroller. I rarely see C programmers that know how to address direct memory locations, or know what the above code does.
And with C i can write something like this and get more efficient code than most asm coders do:
int sum = 0;
for(i=0;i++;i<100)
{
sum += value_table;
}
If I have enought memory (as I usually do with modern microcontrollers), I can tell my compiler to unroll the loop.. who asm compiler bothers to do that kind of optimization (by hand)?

But I have ample of computer to mess up with at school. Rather I would be happy to run it there if it can really mess up the computer. Right now, I'm using a rather slow internet connection, so I will watch Demoscene videos when I get back home. Thank you.
