Bar (unit) (symbol: cbar), and millibar (symbol: mbar or mb). The notation bar(g), though deprecated by various bodies, represents gauge pressure, i.e., pressure in bars above ambient or atmospheric pressure. The bar is defined using the SI derived unit, pascal: ≡ 100,000 Pa ≡ 100,000 N/m. Thus, is equal to: and 1 bar is approximately equal to: Notes: The word "bar" has its origin in the Greek word (), meaning weight. The unit's official symbol is bar; the earlier symbol b is now deprecated and conflicts with the use of b denoting the unit barn, but it is still encountered, especially as
Single Compilation Unit For example, if you have the source files foo.cpp and bar.cpp, they can be placed in a Single Compilation Unit as follows: Suppose foo.cpp and bar.cpp are: //foo.cpp int main() // Definition of function 'main' //bar.cpp void bar() // Definition of function 'bar' Now the standard header file (iostream) is compiled only once, and function bar may be inlined into function main, despite being from another module. Single Compilation Unit Single Compilation Unit (SCU) is a computer programming technique for the C and C++ languages, which reduces serial compilation time and allows the compiler to perform certain program optimizations even
