Q:

Using "if else" inside a function gives unexpected keyword_end error

I have defined a function which looks like this:
def putValAndmyBool val mybool
    if mybool
        puts val + "true"
    else
        puts val + "false"
    end
end

It gives the following error: 

SyntaxError: (irb):101: syntax error, unexpected tIDENTIFIER, expecting ';' or '(irb):107: syntax error, unexpected keyword_end, expecting end-of-input
          from K:/Ruby22-x64/bin/irb:11:in `'

But when I defined following function, it runs successfully. The reason I tried doing this is I thought something in line puts val + "true" is causing the issue.
def addbool val
    puts val + "true"
end

A:

This line is incorrect
def putValAndmyBool val mybool

I suppose should be
def putValAndmyBool val, mybool
