Arduino / C++ - IF INT value = X Then

Question

i have an INT in my arduino code that i constantly update it's value and i want to check the value and compare it to static values and run IF statments out of it. Something like this

INT = 3

If (int = 1) { run1() }
If (int = 2) { run2() }
If (int = 3) { run3() }

the above example just overwrites the original INT value

`=` is the assignment operator. Use `==` to compare. – user4581301 Jul 19 '20 at 17:57 — user4581301, Jul 19 '20 at 17:57
`=` would be an assignment. For a comparison you need `==`. – CherryDT Jul 19 '20 at 17:57 — CherryDT, Jul 19 '20 at 17:57

In C++ = is the assignment operator. Please use == to compare:

int i = 3;

if (i == 1) { run1(); }
if (i == 2) { run2(); }
if (i == 3) { run3(); }

Also note the lowercase if and that int is a keyword which you can't use as variable name.
