Using count += 1, code won't change value in output


#1

This is supposed to count every line in a file that contails the string
‘0004343’ however, when I use the puts it will only output 1 and 0. My
file contains 8 instances of ‘0004343’ so I know that this isn’t right.
I was thinking that it never changes the value to what happens to it in
the while loop. I know this is probably really simple. I just can’t get
it. Please help me? MC

@count = 1
@total = 0
while line = f1.gets
if f1.gets =~ /0004343/ then
@total = @count+= 1
end
end
puts @count
puts @total

@total = @count+= 1

end
puts @count
puts @total

Change line 4 to:
if line =~ /0004343/ then

You read twice from the file.

f1.grep(/0004343/).size
