Ahead of the C99 conventional, variable-sized arrays have been a common illustration of this. (See the report on malloc for an example of dynamically allotted arrays.) Compared with automatic allocation, which might are unsuccessful at run time with uncontrolled repercussions, the dynamic allocation functions return an indication (in the form of a null pointer price) if the essential storage can not be allotted. (Static allocation that is way too large is frequently detected from the linker or loader, right before the program can even begin execution.)

The initial PDP-eleven version of Unix was made in assembly language. The developers were contemplating rewriting the program using the B language, Thompson's simplified Model of BCPL. Having said that B's inability to take full advantage of a lot of the PDP-11's capabilities, notably byte addressability, led to C. The title of C was picked out simply just as the next immediately after B.[eleven]
