Given: an int variable k, an int array currentMembers that has been declared and initialized, an int variable memberID that has been initialized, and an boolean variable isAMember, write code that assigns true to isAMember if the value of memberID can be found in currentMembers, and that assigns false to isAMember otherwise. Use only k, currentMembers, memberID, and isAMember.

Given: an int variable k, an int array currentMembers that has been declared and initialized, an int variable memberID that has been initialized, and an boolean variable isAMember, write code that assigns true to isAMember if the value of memberID can be found in currentMembers, and that assigns false to isAMember otherwise. Use only k, currentMembers, memberID, and isAMember.

Language: Java

Challenge:

Given:

  • an int variable k,
  • an int array currentMembers that has been declared and initialized,
  • an int variable memberID that has been initialized, and
  • an boolean variable isAMember,

write code that assigns true to isAMember if the value of memberID can be found in currentMembers, and that assigns false to isAMember otherwise. Use only k, currentMembers, memberID, and isAMember.

Solution:


for(k=0,isAMember=false;
k<currentMembers.length &&
!isAMember;
isAMember=
(currentMembers[k++]==
memberID));
