Answer:

True

Explanation:

While programming in most programming languages, one will have need to use functions and variables defined in other class libraries. in C++, these functions and variables' definitions are contained in Header files, which can be imported and used into any C++ program by using the pre-processor #include statement. This statement is the equivalent of import in java and copy in other languages. Popular header files are the Maths class (Allows use of maths functions like power, square roots exponentiation etc), the input/output (allows usage of cout print statement and cin input statement)

The CMOS battery located on a computer's motherboard allows for maintaining the correct time and date information stored in CMOS

siniylev [52]

Answer:

True

Explanation:

CMOS (complementary metal-oxide-semiconductor) is a chip which is placed on the motherboard in order to store the system date and time and this is powered by a CMOS battery which is housed inside this chip and is used to manage the date and time when the system is off.
This is a long lasting battery which can work till the life of a motherboard.
This battery is also used to maintain BIOS settings and hardware settings and BIOS uses it during the booting process in order to retrieve the stored information regarding the hardware or system date time.
CMOS chip is basically volatile and cannot retain settings information when the computer system powers off but the CMOS battery helps to maintain these setting just like system time and date when the computer gets shut down.

#include <iostream>

#include <math.h>

using namespace std;

// C++ program to illustrate

// how to calculate BMI

float BMI(float height, float weight)

{

float bmi = weight / pow(height, 2);

return bmi;

}

int main()

{

float height = 1.79832;

float weight = 70;

// Function call

float bmi = BMI(height, weight);

cout << "The BMI is " << setprecision(15) << bmi

<< " so ";

// Conditions to find out BMI category

if (bmi < 18.5)

cout << "underweight";

else if (bmi >= 18.5 && bmi < 24.9)

cout << "Healthy";

else if (bmi >= 24.9 && bmi < 30)

cout << "overweight";
