The main tasks of a computer programmer are first, to write programs to solve problems; second, to write them on time as they are needed; and third, to write them clearly by fully

documenting them so that other programmers can understand them. The kinds of problems that are tackled(解决)depend on whether the programmer is working for a computer manufacturer(制造商) or user. The former needs such programs as compilers, assemblers, executives, operating systems, and utility routines. These programs are intermediaries(中间者) between the machine and the commercial programs which are written in one of the high-level languages. They are about the system, and therefore programmers who write them are called system programmers. If the programmer is working for computer users, however, his or her programs may deal with either scientific or commercial problems.
