  2. C date and time functions - Wikipedia

    en.wikipedia.org/wiki/C_date_and_time_functions

    t. e. The C date and time functions are a group of functions in the standard library of the C programming language implementing date and time manipulation operations. [1] They provide support for time acquisition, conversion between date formats, and formatted output to strings.

  3. Bitwise operations in C - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operations_in_C

    1. 1. 1. The bitwise AND operator is a single ampersand: &. It is just a representation of AND which does its work on the bits of the operands rather than the truth value of the operands. Bitwise binary AND performs logical conjunction (shown in the table above) of the bits in each position of a number in its binary form.

  4. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    Operators in C and C++. This is a list of operators in the C and C++ programming languages. All the operators (except typeof) listed exist in C++; the column "Included in C", states whether an operator is also present in C. Note that C does not support operator overloading . When not overloaded, for the operators &&, ||, and , (the comma ...

  5. Time–temperature superposition - Wikipedia

    en.wikipedia.org/wiki/Timetemperature...

    Here t is the time, G is the modulus, and T 0 < T 1 < T 2. Temperature dependence of elastic modulus of a viscoelastic material under periodic excitation. The frequency is ω, G' is the elastic modulus, and T 0 < T 1 < T 2. The timetemperature superposition principle is a concept in polymer physics and in the physics of glass-forming liquids.

    Isothermal transformation diagram. Time-Temperature-Transformation diagram for two steels: one with 0.4% wt. C (red line) and one with 0.4% wt. C and 2% weight Mn (green line). P = pearlite, B = bainite and M = martensite. Isothermal transformation diagrams (also known as time-temperature-transformation ( TTT) diagrams) are plots of temperature ...

  7. Antenna gain-to-noise-temperature - Wikipedia

    en.wikipedia.org/wiki/Antenna_gain-to-noise...

    This parameter is written as G/T, and has units of dB·K −1. G/T Calculation. G/T is the figure of merit for a satellite system. G is the Receive antenna gain. T is the system noise temperature. System noise temperature = antenna noise temperature + Receiver noise temperature (LNA)

  8. C standard library - Wikipedia

    en.wikipedia.org/wiki/C_standard_library

    The C standard library or libc is the standard library for the C programming language, as specified in the ISO C standard. [1] Starting from the original ANSI C standard, it was developed at the same time as the C library POSIX specification, which is a superset of it. [2] [3] Since ANSI C was adopted by the International Organization for ...

  9. C (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_(programming_language)

    C ( pronounced / ˈsiː / – like the letter c) [ 6 ] is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems code (especially in kernels [ 7 ...
