what is integers related to myvariables?

Question

i changed
int myVariables = 10;
cout << myVariables;
to
int only = 10;
cout << only;
it still run... why we used myVariables if it can still run with other character?

Answer 1

A variable is a placeholder for a value.
You could name it "abcdefg" or "SoloLearnIs Cool" and it would still work.
The courses use myVariables so it can be easier to understand.
If you used a variable named "age" for someone's name it wouldn't make sense now would it?
