Talvez deva tentar algumas variações de ortografia:
coder identifiers » code identifiers (Expandir a busca), code identities (Expandir a busca), poder identified (Expandir a busca)
identifiers c » identifiers in (Expandir a busca), identifiers of (Expandir a busca), identifiers to (Expandir a busca)
c programming » _ programming (Expandir a busca), cone programming (Expandir a busca), and programming (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder identifiers c programming ) OR ( api python python python programming ))~.
