Answer:
import java.util.Scanner;
public class DashLine {
public static void main(String[] args) {
// Declaring variables
int n;
/*
* Creating an Scanner class object which is used to get the inputs
* entered by the user
*/
Scanner sc = new Scanner(System.in);
// Getting the input entered by the user
System.out.print("Enter a number :");
n = sc.nextInt();
// calling the method by passing the user entered input as argument
dashedLine(n);
}
//This method will print the dashed line for number greater than zer
private static void dashedLine(int n) {
if (n > 0) {
for (int i = 1; i <= n; i++) {
System.out.print("-");
}
System.out.println();
}
}
}
Explanation:
Because machine (cpu) can only execute machine code(language).
if the question is if she should..
Explanation:
Yes, she should if she plans to use it for a couple years she should get the best anti virus software :)
Answer:
Constant
Explanation:
A default argument is a value provided in a function declaration that the compiler automatically assigns if the function caller does not provide a default value for the argument.
The value of a default argument must be constant.
The default value parameter must be a constant for compiling. Compiler does not accept dynamically calculated value against optional parameter. The reason behind this it is not certain that the dynamic value you provide would offer some valid value.
<u>Example:</u>
#include<iostream>
using namespace std;
/*A function with default arguments, it can be called upto 4 arguments*/
int sumnum(int x, int y, int z=0, int w=0)
{
return (x + y + z + w);
}
int main() //driver function
{
cout << sumnum(10, 15) << endl;
cout << sumnum(10, 15, 25) << endl;
cout << sumnum(10, 15, 25, 30) << endl;
return 0;
}
<u>Output</u>
<u>25
</u>
<u>50
</u>
<u>80</u>
