Find the mistakes

[omgaga]

OK, i can't figure out what kind of mistake I've done. Can somebody help me please.

#include<iostream>
#include<iomanip>
using namespace std;
void scedulejeff (char [][4]);
void sceduleanna (char [][4]);
void Print2DArray(char [][4]);

int main()
{
	char jeffarray [4][4];
	char annaarray [4][4];
	char instructor;
	
	cout << "What instructor would you like to scedule a time slot for, for Jeff enter j, for Anna enter a?\n";
	cin >> instructor;
	if ((instructor==j) || (instructor==J))
	{
		scedulejeff (jeffarray);
		
	}
	if else ((instructor==a) || (instructor==A))
	{
		scedulejeff (annaarray);
	}
	else 
	{
		cout << "you entered an invalid charater please enter a 'j' for Jeff or 'a' for Anna.\n";
	}
	
}

i'm using xcode... it says there's something wrong with row 11.

instructor=='j' instead of instructor==j instructor=='J' instead of instructor==J instructor=='a' instead of instructor==a instructor=='A' instead of instructor==A

[omgaga]

thanks.... but still....

click this pic to see the problem...

It should be else if instead of if else and there is nothing wrong with line 11. It is just warning message stated that annaarray is declared but is not used.

ok, i think i got everything right. would you mind double check it i've done something wrong... :)

What does variable X do?

[omgaga]

declare all the X is switch statement. why?
