Question

C# Programming

Explain in your own words how using the control selection ( decision) structure is useful in programming in general. Provide Example

Answer 1

Control selection statements

They help in testing the conditions provided by the user

If a particular condition is true then it will execute some set of statements

If condition evaluates to false it will execute some other set of statements

Helps in making decisions based on some set of conditions

Used to control the flow of execution of statements

Some decision making structures are

If

If else

Nested if else

Switch

If statement has some set of Boolean expressions which are followed by some statements

Similarly each has it's own functions and can be used based on the program we are writing

I will execute the code and edit my answer

example of if :

using System;
namespace Demo {
  public class A {
     public static void Main(string[] args) {
       int c=7;
       if(c==7)
Console.WriteLine("Value is 7");
     }
  }
}

example of else :

using System;

namespace Demo {

public class A {

public static void Main(string[] args)

{

int c=7;

if(c==7)

Console.WriteLine("Value is 7");

else

{

Console.WriteLine("Value is not 7");
}

}

}

}

we can use elseif if we have more than 2conditions

switch example

namespace Constants {
public class swi {
 public static void Main(string[] args) {
  char grade = 'A';
  switch (grade) {
   case 'A':
    Console.WriteLine("A grade");
    break;
   case 'B':
    Console.WriteLine("B grade");
    break;
   
   default:
    Console.WriteLine("Failed");
    break;
  }
 }
}
}

Thus switch is used.Similarly we can add more cases based on the code.
