Answer:
Following is the program in C++ Language
#include <iostream> // header file
using namespace std; // namespace std
int main() // main method
{
int n; // variable declaration
cout<<" Please enter the number :";
cin>>n; // Read the number
if(n>0) // check the condition when number is positive
{
cout<<n<<endl<<"The number is Positive"; // Display number
}
else if(n<0) // check the condition when number is Negative
{
cout<<n<<endl<<"The number is Negative";// Display number
}
else // check the condition when number is Zero
{
cout<<n<<endl<<"The number is Zero";// Display number
}
return 0;
}
Output:
Please enter the number:
64
The number is Positive
Explanation:
Following are the description of the program
- Declared a variable "n" of int type.
- Read the value of "n" by user.
- Check the condition of positive number by using if block statement .If n>0 it print the number is positive.
- Check the condition of negative number by using else if block statement If n<0 it print the number is negative.
- Finally if both the above condition is fail it print the message " The number is Zero"
The Dialog Box gives extra data and demand client input. The Dialog Box is thought to be a transitory window an application makes to recover client input. An application regularly utilizes exchange boxes to incite the client for extra data for menu things. An exchange box for the most part contains at least one controls with which the client enters content, picks alternatives, or coordinates the activity.
Answer:
The program to this question can be given as:
Program:
public class Main //define class.
{
public static void main(String[] as) //define main method.
{
int n=5; //define variable n and assign positive value.
int i,j; //define variable
for (i = 7; i>=1; i--) //outer loop.
{
for (j = 0; j< i; j++) //inner loop.
{
System.out.print("*"); //print asterisks.
}
System.out.println(); //line break.
}
}
}
Output:

Explanation:
The description of the above code can be given as:
- In the above java programming code firstly we define a class that is "Main". In this class we define a main method in the main method we define a variables that is "n" in this variable we assign a positive value. The we define another integer variable that is i,j this variable is used in the loop.
- Then we define a loop. for prints asterisks values in reverse triangle, we nested looping concept. In nested looping, we use in loop in this loop we use the i and j variables that print the asterisks value.
