Given that a function receives three parameters a, b, c, of type double , write some code, to be included as part of the functio

hoa [83]

Answer:

public static void quad(double a, double b, double c) {

double D = (Math.pow(b, 2)) - (4 * a * c);

if (D<0){

System.out.println("no real solutions");

}

Explanation:

The code snippet above implements the function in Java programming language

As required by the question, the line double D = (Math.pow(b, 2)) - (4 * a * c); evaluates b squared" - 4ac and assignes the value to the variable D

An if statement is used to test if D is less than 0, if this is true the message no real solutions is printed

What will be displayed after the following code executes? (Note: the order of the display of entries in a dictionary are not in

iren [92.7K]

Answer:

Nothing will be printed

Explanation:

You can easily find out that FL is not a member of the Dictionary. And we are checking these in the if. Since the if condition ends up being false, the further process will not run as they will only if the condition ends up being true. Hence, nothing will be printed.

Remember, del is used to delete a dictionary item. If this would have been a true condition for if then the FL item in the dictionary would have been deleted as it, in that case, would have been present there. And then the next line would have again added the FL item, and print would have printed the dictionary items with FL item as well. However, since if the condition is ending up being false, nothing will be printed.

If cities['FL'] and print is outside if then

the output will be

{'FL': 'Tallahassee', 'GA': 'Atlanta', 'NY': 'Albany', 'CA': 'San Diego'}

What stdio.h input function would be used to get input from the user by the keyboard? Write the code to obtain the voltage drop

torisob [31]

Answer:

scanf() function is used to get a input from keyboard.This function is in the stdio.h library.To use this function we must include the stdio.h library first in the code. Then only we can use the scanf() function in any code.printf() function is used to print anything .this function is from stdio.h library.

Code to read voltage drop across the register.

#include <stdio.h>

// main function

int main(void) {

// variable

double vr1;

printf("Enter voltage drop:");

// read voltage drop from user

scanf("%lf",&vr1);

// print voltage drop

printf("voltage drop is:%0.2lf",vr1);

return 0;

}

Output:

Enter voltage drop:200.4

voltage drop is:200.40
