C Increment and Decrement Operators. C programming has two operators increment ++ and decrement --to change the value of an operand (constant or variable) by 1.. Increment ++ increases the value by 1 whereas decrement --decreases the value by 1. These two operators are unary operators, meaning they only operate on a single operand.
C - Operators - An operator is a symbol that tells the compiler to perform specific mathematical or logical functions. C language is rich in built- in operators and provides the
= Simple assignment operator. Assigns values from right side operands to left side operand C = A + B will assign the value of A + B to C += Add AND assignment operator. It adds the right operand to the left operand and assign the result to the left operand. C += A is equivalent to C = C + A ...
'a' is an ASCII BEL character it is a terminal feature it produces a "beep" sound or a notification sound simultaneously displaying a terminal or command ...
btw, you must run the program from a terminal, since beeping when printing 'a' is a terminal feature (not C nor OS feature). - Lie Ryan Oct 2 '10 at 12:51 @Lie Ryan I've also tried it in terminal but no beep sound.I typed the following command printf 'a' on the terminal but nothing happened...
The character coded 007 in octal, 0x07 in hex, or as a in a C character or string constant rang the bell when received. As terminals became smaller and implemented with few or no moving parts, the physical bell was replaced by a beeper.
Escape Sequence in C . An escape sequence in C language is a sequence of characters that doesn't represent itself when used inside string literal or character. It is composed of two or more characters starting with backslash . For example: represents new line. List of Escape Sequences in C
All Escape Character have its importance in C++. I am sending u some common Escape characters. a = alarm or alert = it is used for backspace.
In the early C compilers, the three previous expressions may have produced different executable code depending on which one was used. Nowadays, this type of code optimization is generally performed automatically by the compiler, thus the three expressions should produce exactly the same executable code.
