OK, but one can usually rely on C compilers to generate code 
approximately proportional to the size of the C code. That is
not true for most other high-level languages.

There are some that one can hope for, but never really know.

One that I have wondered is which compilers recognize a / and %
usign the same operands, and do one divide instruction that returns
both quotient and remainder. (As hardware often does.)

C is low enough that many tasks that previously required 
assembler can now be done in C.

But even more, many C operands correspond to operations on
the usual processors. 

As one example, Fortran has the ISHFT function to perform bit
shifting, which shifts left for a positive shift amount, right
for a negative amount. Sometimes convenient, but not directly
supported by most processors. ISHFT also allows the shift amount
to equal the bit width of the operand, again requiring extra tests.

So, yes, C isn't an assembler, but often enough it doesn't promiss
more than the hardware provides.

For another view, consider PL/360. PL/360 is a high-level (looking)
language that directly maps to S/360 instructions. This becomes
obvious in some example cases:

   R1 := R1+R1+R1;

quadruples the value in R1 (register 1). Specifically:

   LR  R1,R1
   AR  R1,R1
   AR  R1,R1

changes to registers take effect immediately, unlike changes
to C variables.
