Read lines starting from a line number in a bash script

Question

I'm trying to read a file line by line starting from a specific line in bash. I have already used the while command to read each line of the file by incrementing the count. Can I make it start from a specific line?

let count=0
declare -a ARRAY

while read LINE; do
ARRAY[$count]=$LINE 
vech=${ARRAY[$count]}
    if [...blah ..]
     then
    ...blah..
    fi 
sleep 2 
((count++)) 
done < filec.c 

Any kind of help in the form of suggestions or algorithms are welcome.

Edit: I'm trying to pass the line number as a variable . I am Grepping for a specific pattern and if found, should pass the line number starting from the pattern.

Just keep a counter. To print all lines after a certain line, you can do like this:

#!/bin/bash

cnt=0
while read LINE
do
    if [ "$cnt" -gt 5 ];
    then
        echo $LINE
    fi
    cnt=$((cnt+1))
done < lines.txt

or, why not use awk:

awk 'NR>5' lines.txt
