Question

In evaluating a loop, you find the following statement:

Answer 1

Answer:

D) The variable is increased by 1 each iteration through the loop

Explanation:

In Most popular programming languages such as java, c++, python etc, there is a variance to the simple assignment operator. (=). This variance is called a compound assignment operator. Compound operators come in different styles for example

x = x+1 equivalent x+=1

x = x-1 equivalent x- =1

x = x/y equivalent x/=y

In the question scenario value += 1 is equivalent to value = value+1. Compound operators are important in providing short hands while coding as well as helping the programmer from having to cast variable types explicitly
