Cette fois, je vais vous présenter la mise en œuvre de la fonction de recherche de première lettre dans le carnet d'adresses. Quelles sont les précautions à prendre pour mettre en œuvre la fonction de recherche de première lettre dans le carnet d'adresses. Ce qui suit est un cas pratique, jetons un coup d'oeil.
Le code principal est le suivant :
