How can you change the value of a constant variable in C?

You can change a static variable by putting the static variable into a function that has operations that you intend to execute upon the variable. Example, you want to change the static variable to another value or make an addition of 2. Put the source code inside a function with the static variable declared locally within the function.

Every time you call the function, the static variable value will change. Take note that the static variable retains the last value you declared it in your function call.

A more terse answerLocal variables declared as static are changed as normal; they are special in that their values persist across function calls.
