Page "System programming language" Paragraph 4

Subsequently, languages such as C were developed, where the combination of features was sufficient to write system software, and a compiler could be developed that generated efficient object programs on modest hardware.

Such a language generally omits features that cannot be implemented efficiently, and adds a small number of machine-dependent features needed to access specific hardware capabilities ; inline assembly code, such as C's < tt > asm </ tt > statement, is often used for this purpose.

Although many such languages were developed, C and C ++ are the ones that have survived.
