Estruturas de dados - struct com Menus Inteligentes em Linguagem C puro.
Esta estrutura é do tipo estática usando é claro vetor estático.
O programa é todo criado em funções simples, que são chamadas por um
menu inteligente com teclas do teclado do computador, e confirmado pela
tecla "ENTER", muito seguro,menu de um funcionamento excelente e o código é
100 por cento funcional, gastei muito tempo pra deixá-lo funcionando, criado
pacientemente na minha IDE padrão, o eclipse é claro, e está rodando liso,
e leve como uma pluma, por aqui não foi detectado nenhum warnings, quando foi compilado pelo mingw32-3.4.2.
Apesar de tudo isto eu recomendo o código a iniciantes em Linguagem C,
que estão aprendendo montar estruturas para cadastro, com inserção, listagem, alteração e remoção.
Veja abaixo um vídeo com o funcionamento do Programa:
Veja abaixo o código do programa:
