Answer

በKotlin ውስጥ፣ ከተጀመረ በኋላ ዳግም ሊመደብ የማይችል ተለዋዋጭ (variable) ለመግለጽ፣ val ቁልፍ ቃል (keyword) ጥቅም ላይ ይውላል።

  • val ተለዋዋጭ አንዴ ዋጋ ከተሰጠው በኋላ ሊቀየር እንደማይችል ያመለክታል።
  • var ተለዋዋጭ ደግሞ ዋጋው ሊቀየር የሚችል መሆኑን ያመለክታል።
  • let ለተግባራት ወሰን (scoping functions) የሚያገለግል ሲሆን ተለዋዋጭ ለመግለጽ አይደለም።
  • const ደግሞ በኮምፓይል ጊዜ (compile-time) ለሚታወቁ ቋሚዎች (constants) ብቻ የሚያገለግል ነው።

ስለዚህ ትክክለኛው አማራጭ val ነው።
