Use constexpr for constants whose value is known at compile time. (Con.5)

Code analysis name: USE_CONSTEXPR_RATHER_THAN_CONST

Example

const int foo = 1234;  // C26814 reported here.
constexpr int getMagicNumber()
{
    return 42;
}

void bar()
{
    const int myval = 3; // C26814 reported here
    const int magicNumber = getMagicNumber(); // C26814 reported here.
