Variable type is necessary to understand to provide a valid value to that variable. In this answer, we'll learn how to get the type of a variable in Julia.
Julia provides a function typeof() to get the type of the variable.
typeof(provide your variable name here)
This function takes a variable name as a parameter and returns its type.
Let's take a look at an example of this.
var1 = 10#display type of var1println("Type of variable var1 is ", typeof(var1))var2 = 10.5#display type of var2println("Type of variable var2 is ", typeof(var2))var3 = "Hello from Educative !!!"#display type of var3println("Type of variable var3 is ", typeof(var3))var4 = [1, 3, 5, 7, 9]#display type of var4println("Type of variable var4 is ", typeof(var4))
Line 1: We declare and initialize a variable var1 with an integer value.
Line 4: We get the type of a variable var1 using the typeof() function.
Line 6: We declare and initialize a variable var2 with a float value.
Line 9: We get the type of a variable var2 using the typeof() function and display it.
Line 11: We declare and initialize a variable var3 with a string value.
Line 14: We get the type of a variable var3 using the typeof() function.
Line 16: We declare and initialize a variable var4 with a vector of integer value.
Line 19: We get the type of a variable var4 using the typeof() function and display it.
