I am studying networks and a question has arisen regarding IP addressing.

IP addresses are class A, B and C mainly.

  • The A indicates that there are 8 bits for the network and 24 bits for the host, that means that I have 256 possible networks and 16 million computers for each network, right?
  • The B indicates that there are 16 bits for network and 16 for host, that means 65,000 networks and 65,000 computers in each network?

Please someone explain to me what I'm doing wrong...

Very good.

I have to perform the following exercise: find a word in a sentence, both strings entered by the user. I have done the following:

//i controla posiciones de cadena
//k controla posiciones de palabraCadena
//principio guardará la posicion en la que se encontraría el primer caracter
//palabra guarda la palabra del usuario
//palabraCadena va copiando palabra a palabra de la frase
//encontrado guarda 1 si la palabra ha sido encontrada y 0 si no

void buscarPalabra (char cadena[]){
    int i, k=0, principio=0;
    char palabra[20];
    char palabraCadena[50];
    int encontrado=0:
    
    printf("Introdue la palabra que deseas buscar: ");
    fflush(stdin);
    fgets(palabra,10,stdin);
    palabra[strlen(palabra)-1]='\0';
    
    pausa();
    
    printf("BUSCAR PALABRA\n");
    printf ("--------------\n");
    printf ("Cadena considerada: %s\n", cadena);
    printf ("Palabra a buscar: %s\n", palabra);
    
    i=0;
    while (i<strlen(cadena)+1){
        principio=i;
        k=0;
        while (cadena[i]!=' ' && cadena[i]!='\0'){
            palabraCadena[k]=cadena[i];
            i++;
            k++;
        }
        
        if (strcmp(palabraCadena,palabra)==0){
            encontrado=1;
            break;
        }
        
        i++;
    }
    
    if (encontrado==1){
        printf ("La palabra se ha encontrado en la posicion %i.\n", principio);
    } else {
        printf ("La palabra no ha sido encontrada.\n");
    }
}

The problem is that when I print what is being saved wordString, it saves my, car, esche, white, ... World, and I don't really understand why. In this way, ''my'' and ''car'' finds them, but everything after this doesn't... For data, I use Dev C++ as the compiler.

Thanks in advance.
