Enter the output of the integer expressions.
x = 2
y = x * 5
print (y)
Answer (2)
The variable x is assigned the value 2.
The variable y is calculated as y = x ∗ 5 .
Substituting the value of x, we get y = 2 ∗ 5 = 10 .
The program prints the value of y, which is 10 .
Explanation
Understanding the Program We are given a simple program that assigns the value 2 to the variable x, then calculates y as x * 5, and finally prints the value of y. Our goal is to determine the output of this program.
Substituting the Value of x First, we substitute the value of x into the expression for y: y = x ∗ 5 = 2 ∗ 5 .
Calculating the Value of y Next, we calculate the value of y: y = 2 ∗ 5 = 10 .
Determining the Output Therefore, the program will print the value of y, which is 10.
Examples
Imagine you are writing a program to calculate the total cost of items. If each item costs $5 and a customer buys 2 items, this simple program demonstrates how to calculate the total cost: total_cost = number_of_items * cost_per_item. This basic calculation is fundamental in many real-world applications, from simple shopping calculations to more complex financial computations.
The program calculates the value of y by multiplying the variable x, which is 2, by 5. The result is y = 10, which is printed as the output of the program. Therefore, the output of the integer expressions is 10.
