Unless you explicitly initialize global variables, they are automatically initialized to
shusha [124]

Answer:

Zero(0)

Explanation:

<u>Global Variables </u>

Variables which are declared outside any function. Any function can use these variables,they are automatically initialized to zero(0).They are generally declared before main() function.

Example- C program for showing global variable is 0.

  #include <stdio.h>

   int g;  // declaring g as global variable

   int main()

   {

       printf("%d",g);  //printing global variable

       return 0;

    }

<u>Output</u>

  0

Consider the following code: public static void mystery(int a) { System.out.println("A"); } public static void mystery(double a)
Feliz [49]

Answer:

The output is "A"

Explanation:

public class Solution {

   public static void main(String args[]) {

     mystery(7);

   }    

   public static void mystery(int a) { System.out.println("A"); }    

   public static void mystery(double a) { System.out.println("B"); }    

   public static void mystery(int a, double b) { System.out.println("C"); }    

   public static void mystery(double a, int b) { System.out.println("D"); }

}

In the code above; mystery is defined in four different ways called method overloading. Method overloading is when same method is defined with different parameters.

In the first case; mystery will be called if the argument is int.

In the second case; mystery will be called if the argument is double.

In the third case; mystery will be called if the arguments are int and double.

In the fourth case; mystery will be called if the arguments are double and int.

When mystery(7) is called; the mystery method requiring only int will be called and the output is "A".

Write an algorithm to find perimeter of circle<br>​
Anna11 [10]

Answer:

Here’s one!

Given [math]R[/math], the radius of the circle.

Let [math]N,D\leftarrow 0[/math]

Repeat until [math]D[/math] is large enough (about 1,000,000)

[math]x,y\leftarrow U[0,1][/math]

If [math]x^2 + y^2\le 1[/math] then [math]N\leftarrow N+1[/math]

[math]D\leftarrow D+1[/math]

[math]P\leftarrow\frac{8NR}{D}[/math]

Return [math]P[/math]

[math]U[0,1][/math] is a uniform random number in the range [math][0,1][/math].
