=== Notas e Advertências
Note que `sizeof` retorna o número total de bytes. Então, para os tipos de dados maiores, como ints, o loop for parece algo do tipo abaixo.

for (i = 0; i < (sizeof(meusInts) / sizeof(int)); i++) {
// faz algo com meusInts[i]
int meusValores[] = {123, 456, 789};

// this for loop works correctly with an array of any type or size
for (i = 0; i < (sizeof(meusValores)/sizeof(meusValores[0])); i++) {
// fazer algo com meusValores[i]
