  2. Ternary conditional operator - Wikipedia

    en.wikipedia.org/wiki/Ternary_conditional_operator

    The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...

  3. C shell - Wikipedia

    en.wikipedia.org/wiki/C_shell

    Shell variables, created using the set or @ statements, are internal to C shell. They are not passed to child processes. Shell variables can be either simple strings or arrays of strings. Some of the shell variables are predefined and used to control various internal C shell options, e.g., what should happen if a wildcard fails to match anything.

  4. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    For example, += and -= are often called plus equal(s) and minus equal(s), instead of the more verbose "assignment by addition" and "assignment by subtraction". The binding of operators in C and C++ is specified (in the corresponding Standards) by a factored language grammar, rather than a precedence table.

  5. Conditional (computer programming) - Wikipedia

    For example: If stock=0 Then message= order new stock Else message= there is stock End If. In the example code above, the part represented by (Boolean condition) constitutes a conditional expression, having intrinsic value (e.g., it may be substituted by either of the values True or False) but having no intrinsic meaning

  6. Relational operator - Wikipedia

    The former code fragment means "assign y to x, and if the new value of x is not zero, execute the following statement". The latter fragment means "if and only if x is equal to y, execute the following statement". [12]

  7. Bitwise operations in C - Wikipedia

    Thus by doing ch << 1 in the above example (11100101) we have 11001010. Blank spaces generated are filled up by zeroes as above. However, do note that a shift operand value which is either a negative number or is greater than or equal to the total number of bits in this value results in undefined behavior.

  9. NOP (code) - Wikipedia

    en.wikipedia.org/wiki/NOP_(code)

    In the case of both the NOP and NOPR instructions, the first 0 in the second byte is the "mask" value, the condition to test such as equal, not equal, high, low, etc. If the mask is 0, no branch occurs. In the case of the NOPR instruction, the second value in the second byte is the register to branch on.
