As you might already be able to tell, this basic program takes the value of an integer variable (‘i’) and compares it to a constant integer (2). As the condition is true (in other words, ‘i’ is less than 2), the string on the following line will then be printed to the scre...
As we mentioned earlier, so-called “power-users” of the terminal will use it to perform as many tasks as possible. This is also true for coding in the text-based environment, as you can easily script and automate your build processes without needing to navigate sub-windows to find the ...
Currying is when you break down a function that takes multiple arguments into a series of functions that each take only one argument. Here's an example in JavaScript: function add (a, b) { return a + b; } add(3, 4); // returns 7 This is a function that takes two arguments, a...
variable is the independent samples t-test , illustrated below. in this test, the dichotomous variable defines groups of cases and hence is used as a categorical variable. strictly, the independent-samples t-test is redundant because it's equivalent to a one-way anova . however, the ...
The value of the variable is copied to a temporary location The temporary value is incremented to produce a new value (not overwriting the temporary!) The new value is stored in the variable The result of the operation is the value of the temporary Some things to notice: First, the order...
On lines 7 and 8, an element of the list modifies the value of a variable that is used in another element. The ambiguity in the evaluation order can cause unexpected values. For instance, arr2[] can be initialized with{1,1}or{1,2}, depending on the order in which x++ is evaluated...
In the example above, a constructor is defined to accept an error message and a private member variable is used to store the error message. You can now throw instances of your exception class within your code using the throw keyword.Example To catch and handle the thrown exception, you can...
