While writing a program, we encounter such situations where we need to decide whether a certain block of code should be executed or not if a certain condition is met. For this purpose, we make use of If and Else statement, which is known as conditional statement. A sample code is given below with its explanation.
static void Main(string args)
int number = 2;
if (number == 1)
Console.WriteLine("The number is 1.");
In the above code, we have assigned a value 1 to the number variable. With the help of If and Else statement, we have made a check for a certain condition before executing the code. If the number value is 2, then the line #13 will be executed else line #17 will be executed.
