Answer:
The code will produce:-
2.4
Explanation:
In this code the result of the arithmetic operation is stored in the variable c.On evaluating the expression it divides 12.0 by 5 which results in 2.4 and it is stored in float variable c.Then it is printed on the screen using print statement.Since the c is double variable so the result will be a decimal number.
Hence the answer is 4.
Answer:
Explanation:
The following code is written in Java. It is a method that calculates the square root of a number as requested. The method first checks with an IF statement if the parameter value is a positive number and then calculates the square root and prints it to the screen. Otherwise, it prints Number must not be negative. A test case has been provided in the main method and the output can be seen in the attached image below.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Enter a number of type double to calculate square root:");
double num = in.nextDouble();
rootPositive(num);
}
public static void rootPositive(double num) {
if (num > 0) {
System.out.println(Math.sqrt(num));
} else {
System.out.println("Number must not be negative.");
}
}
}
Answer:
The complete Matlab code along with step by step explanation is provided below.
Matlab Code:
function Req=ParallelR(Number)
Number=input('Please enter the number of resistors: ');
if Number>10 | Number<=0
disp('Invalid input')
return
end
R=0;
for i=1:Number
r=input('Please enter the value of resistor: ');
R=R+1/r;
end
Req=1/R;
end
Explanation:
Parallel resistance is given by

First we get the input from the user for how many parallel resistors he want to calculate the resistance.
Then we check whether the user has entered correct number of resistors or not that is from 1 to 10 inclusive.
Then we run a for loop to get the resistance values of individual resistors.
Then we calculated the parallel resistance and keep on adding the resistance for N number of resistors.
Output:
Test 1:
Please enter the number of resistors: 3
Please enter the value of resistor: 10
Please enter the value of resistor: 20
Please enter the value of resistor: 30
ans = 60/11
Test 2:
Please enter the number of resistors: 11
Invalid input
Test 3:
Please enter the number of resistors: 0
Invalid input
