Answer: 83.17
Explanation:
By definition, the dB is an adimensional unit, used to simplify calculations when numbers are either too big or too small, specially in telecommunications.
It applies specifically to power, and it is defined as follows:
P (dB) = 10 log₁₀ P₁ / P₂
Usually P₂ is a reference, for instance, if P₂ = 1 mW, dB is called as dBm (dB referred to 1 mW), but it is always adimensional.
In our question, we know that we have a numerical ratio, that is expressed in dB as 19.2 dB.
Applying the dB definition, we can write the following:
10 log₁₀ X = 19.2 ⇒ log₁₀ X = 19.2 / 10 = 1.92
Solving the logarithmic equation, we can compute X as follows:
X = 10^1.92 = 83.17
X = 83.17
Answer:
ofstream asia("asiasales2009.txt"); //It is used to open asiasales2009.txt files with the asia objects.
ofstream europe("europesales2009.txt"); //It is used to open europesales2009.txt files with the europe objects.
ofstream africa("africasales2009.txt");
//It is used to open africasales2009.txt files with the africa objects.
ofstream latin("latinamericasales2009.txt");//It is used to open latinamericasales2009.txt files with the latin objects.
Explanation:
- The above code is written in the c++ language which is used to open the specified files with the specified objects by the help of ofstream class as described in the question-statements.
- The ofstream is used to open the file in the c++ programing language, so when a user wants to use the ofstream to open the file in written mode, then he needs to follow the below syntax--
ofstream object("file_name_with_extension");
