C may refer to any of the following:

C: prompt1. C is commonly used to describe the C: drive or the first hard drive on IBM compatible computers.

C programming book2. The C programming language is a high-level programming language developed by Dennis Ritchie and Brian Kernighan at Bell Labs in 1972 from an almost unknown language named B. The first major program written in C was the Unix operating system, and for many years, C was considered to be inextricably linked with Unix. Below is an example of a C program that prints "Hello World!" after it's been compiled. If you need a free C compiler, consider GCC.

#include <stdio.h>

     printf ("Hello World!\n");

3. C is an abbreviation for Celsius.

4. C represents the scientific unit for the coulomb.

5. The C button on calculators is short for "clear" and is a button used to clear all last numbers and totals. Calculators that have this key may also have a CE button that is used to only clear the last entered number. For example, if several numbers have been entered before the number you're entering now, you can press the CE button only to clear the current number without deleting any prior numbers. If you wanted to clear everything, you could press the C button instead.

6. Shorthand for see or sea. For example, someone may say "ICU" in chat as a short method of typing "I see you."
