Introduction: var keyword in C#
In C# 3.0, the var keyword was introduced to declare an implicit type local variable that could hold any data. However, it’s important to remember that when using var, you must ensure the variable is assigned a value during declaration.
In simpler terms, var lets us create a variable without deciding its type beforehand. It’s like telling the compiler, “Hey, you decide the type based on what value I assign to this variable.” However, it’s important to note that when we declare a variable with var, we must also initialize it with a value right at the beginning.
