The answer would be the CPU (Central Processing Unit). It is essentially the brain of a computer.
Answer:
#include <iostream>
# include <conio.h>
using namespace std;
float fat_burning_heart_rate(float age);
main()
{
float age,bpm;
cout<<"enter the age of the person"<<endl;
cin>>age;
if (age>=18 && age<=75)
{
bpm=fat_burning_heart_rate(age);
cout<<"fat burning heart rate for the age of"<<age<<"="<<bpm;
}
else
cout<<"Invalid age";
getch();
}
float fat_burning_heart_rate(float age)
{
float a;
a= (220-age)*0.7;
return a;
}
Explanation:
In this program, the variable named as age has been taken to enter the age of the person, needs to calculate the burning heart rate. All the variables taken in float, as the age and fat burning heart rate should come in decimal value.
The formula has been used as mention in question that,
a= (220-age)*0.7;
Answer:
a. a syntax error
Explanation:
When the same variable name is repeated in the parameter set and the method body, it will result in a syntax error. This is because the variable in the parameter has a local scope within the method body. Now if we declare another variable with the same name in the method body, it will result in redefinition of the variable and violate the uniqueness principle of variable names in the method code. This will give rise to syntax error.
Answer:(c) abstract class A { abstract void unfinished(); }
Explanation:
A legal abstract class must have the keyword abstract before the class and an abstract class has abstract functions with the keyword abstract written and a void as the return type.
