What is the purpose of the " + " in the code labeled // line 2 below ? int sum;
int num1 = 3;
int num2 = 2;
sum = num1 + num2; // line 1
System. out. println(num1 + " + " + num2 + " = " + sum);// line 2

To illustrate addition operation

Explanation:

Given

The above code segment

Required

Determine the purpose of "+" in label line 2

In line 2, num1 = 3  and num2 = 2 in line 3.

sum = 2 + 3 = 5 in line 4

From the given code segment, the plus sign is used as a string literal (i.e. "+").

This means that, the print statement will output: 3 + 2 = 5

The "+" is printed in between 3 and 2.

So, the purpose of the "+" is to show the function of the program and the function of the program is to illustrate an addition operation between two variables
