Thread: Struct and while

Hi, I have a little problem with this code. When I try to run it, only asks my to write the name (nombre), and jumps to the address (direccion) of the person number 2. Why is happing that?

Code:

int main(int argc, char* argv[])
{
struct persona{
char nombre [65];
char direccion[65];
int telefono;
}gente[5];

int a=0, b=0;

do{
a++;
printf("\nPersona %i\n--------------------", a);

printf("\nIntroduzca el nombre de la persona: ");
scanf("%c", &gente[b].nombre);

printf("\nIntroduzca la direccion de la persona: ");
scanf("%c", &gente[b].direccion);

printf("\nIntroduzca el telefono de la persona: ");
scanf("%i", &gente[b].telefono);
b++;

}while (a < 5);

getch();

        return 0;
}

Thanks,

'\n' is left in the buffer
Flush the buffer

I am having some problems qith this code.

Code:

while((ch=getchar())!='\n' && ch!=EOF);

The compiler gives me an error that says "Undefined symbol ch". What kind of variable has to be ch? Has to have some initial value?. Also, the compiler says me that the "code has not effect", but, perhaps, this'll disappear when the variable ch is correct. Any idea?

Thank you,

Thank you,

In this case you would declare the variable ch to be of type int:

Code:

int ch;  /* no need to intialise it here... */

.....

while((ch=getchar())!='\n' && ch!=EOF) /* ... as it is assigned a value here */

As to the "code has no effect" - can't help you on that one without seeing what code you are using.
