what is printed to the screen if the user enters 5 when the following program is run? var usernum = readint(\enter your favorite number:\); var calculatednum = (usernum * usernum) + usernum; println(calculatednum);
Answer
Explanation:
Step1: Substitute user input
Given userNum = 5, substitute into the formula calculatedNum=(userNum * userNum)+userNum. So we have calculatedNum=(5 * 5)+5.
Step2: Calculate multiplication first
According to the order of operations (PEMDAS), we calculate 5 * 5 first. 5 * 5 = 25. Then the expression becomes 25 + 5.
Step3: Calculate addition
25+5 = 30.
Answer:
30
