GJ! Keep up the good work!
True, RR Lyrae stars pulsate, but with shorter periods and lower luminosities than Cepheids.
The pulsation periods of the fundamental-mode RR Lyrae stars range from about 0.3 to 1.0 days (Population II pulsators with longer periods are categorized as type II Cepheids), but the vast majority of them have generations longer than 0.45 days.
<h3>Why do RR Lyrae stars pulsate?</h3>
RR Lyrae stars pulse like Cepheid variables, but the nature and histories of these stars is thought to be rather different. Like all variables on the Cepheid fluctuation strip, pulsations are caused by the κ-mechanism, when the ambiguity of ionised helium varies with its temperature.

Answer:
123456
Explanation:
When an integer value is added to a string value the resulting value is a string.+ operator is used for both numeric additions and string addition also knows as string concatenation. In addition when one operand of the equation is a string the program interprets all values as string. As system is interpreting all values as a string it will apply a string addition method instead of mathematical addition.So here A is a string and B is an integer value. when we add A and B system will treat B aslo as a string, upon addition the result will be String concatenating both A and B to a single string.Hence the result of A+B will be
A+B = 123456
As WriteLine method takes string as Input it will just write the resulting string to file
