C/C++ program for text processing

We ideally need a C/C++ program to process large (1-2GB+) files.

Two processes are required:

1) Search for and count the occurrences of a specific string of characters

2) Extract all lines (& adjoining information) when the specified string is identified.

Input will be two files:

a) A csv or tsv where each line will contain an individual string to be searched for.

b) A fastq file (this is the larger of the files) which will follow a fastq format.

Required output:

i) A csv or tsv file which contains the string searched for and its corresponding count

ii) A fastq file which contains just those rows (& corresponding information - ie the row above and two below) which contain that specific string.

Given the size of the input fastq file - this cannot be easily loaded into RAM etc.
