Small Steps I — Creating with Text and Numbers
Naming a value that will not change
Set a goal of 200 and print how much more is needed from a current score of 80.
What you will learn
const means the initial value will not be changed later. Use it to name a fixed value such as a game's target score.
Try it
Example · example.cpp
void small_main()
{
const int goal_score = 100;
int score = 80;
print(goal_score - score);
}
Assigning a different value to goal_score later causes a compilation error.
In this course, start names with an English letter and use letters, digits, and underscores. Do not include spaces. score and Score are different names. C++ keywords such as int and if cannot be names.
Expected output:
20
Exercise
