C-- (pronounced cee minus minus) is a C-like programming language. It can be compiled on a variety of computer platforms. Whitespace separates one part of a statement from another and enables the compiler to identify where one element in a statement, such as int, ends and the next element begins. C-- (pronounced cee minus minus) is a C-like programming language.

Its most innovative feature is a run-time interface which allows writing of portable garbage collectors, exception handling systems and other run-time features which work with any C-- compiler. Programs built in machine code are very fast. It subtracts the right operand from the left operand and assigns the result to the left operand.

The UNIX operating system, the C compiler, and essentially all UNIX application programs have been written in C. C has now become a widely used professional language for various reasons −. Unlike many other intermediate languages, its representation is plain ASCII text, not bytecode or another binary format. When a program calls a function, the program control is transferred to the called function. This tutorial assumes that you know how to edit a text file and how to write source code inside a program file. Whitespace is the term used in C to describe blanks, tabs, newline characters and comments. [2] A revised manual was posted in HTML form in May 1999. The C-- type system is deliberately designed to reflect constraints imposed by hardware rather than conventions imposed by higher-level languages. This method copies the actual value of an argument into the formal parameter of the function. C is a successor of B language which was introduced around the early 1970s. Assume variable A holds 10 and variable Bholds 20 then − Show Examples Learn how and when to remove this template message, https://www.cs.tufts.edu/~nr/c--/index.html, "C–: a portable assembly language that supports garbage collection", "The C-- Language Specification, Version 2.0". C was developed in the early 1970s by Ken Thompson and Dennis Ritchie at Bell Labs.It is a procedural language, which means that people can write their programs as a series of step-by-step instructions. Despite the original intention, GHC does perform many of its generic optimizations on C--.
The left operands value is moved right by the number of bits specified by the right operand. A function declaration tells the compiler about a function name and how to call the function.

This means that changes made to the parameter affect the argument. For example, strcat() to concatenate two strings, memcpy() to copy one memory location to another location, and many more functions. Many operating systems, including Linux and UNIX, are programmed using this language. This is done by having the compiler generate C-- code, delegating the harder work of low-level code generation and optimisation to a C-- compiler.
It divides the left operand with the right operand and assigns the result to the left operand. In C--, a value stored in a register or memory may have only one type: bit vector.
