Lynna [10]

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--

Unit 6: Lesson 2 - Coding Activity 1 AP Computer science

sladkih [1.3K]

The complete program is to define a boolean method that returns true if all elements of an array are negative, or return false, if otherwise

The method in java, where comments are used to explain each line is as follows:

//This defines the method

public static boolean chkNegative (double[] myArr) {

//This initializes a boolean variable

boolean isNeg = true;

//This iterates through the array

for (int i = 0; i < myArr.length; i++) {

//If the array element is 0 or positive

if (myArr[i] >= 0) {

//Then the boolean variable is set to false

isNeg = false;

//And the loop is exited

break;

}

//This returns true or false

return isNeg;

}
