This is the code, it simply reads the values and puts it on the list, but in the last loop it stops responding
#include<stdio.h>
#include<stdlib.h>
typedef struct pessoa {
int horas,minutos;
int conversao;
int atendimento;
int critico;
int horacritica;
int horasair;
struct pessoa *proximo;
}paciente;
paciente *cabeca;
paciente *auxiliar;
paciente *anterior;
void insere(paciente *cabeca){
paciente *elemento =(paciente*)malloc(sizeof(paciente));
scanf("%d %d",&elemento->horas,&elemento->minutos);
scanf("%d",&elemento->critico);
if(cabeca->proximo == NULL){
cabeca->proximo = elemento;
} else {
auxiliar->proximo = cabeca;
while(auxiliar->proximo != NULL){
auxiliar = auxiliar->proximo;
}
auxiliar->proximo = elemento;
}
}
int main(){
int N,cout;
cabeca = (paciente*)malloc(sizeof(paciente));
cabeca->proximo = NULL;
printf(" QUANTOS NOS QUER : ");
scanf("%d",&N);
for(cout=1;cout<=N;cout++){
insere(cabeca);
}
return 0;
}
Put some
printfwe strategically position to know what is happening– Jefferson Quesado
I noticed that when I invoked
insere, you are not initiating the value ofelemento->proximo, this can lead to complications. Initialize this value, it may help to avoid an infinite loop in thewhile (auxiliar->proximo != NULL)– Jefferson Quesado
The problem is that always when it arrives at the last loop the algorithm stops responding and error. Like, he doesn’t even read all the figures and the IDE hangs here D:

Make my two suggestions from previous comments. If not resolved, you will be closer to the answer
– Jefferson Quesado
It worked. A doubt here, there is a difference between doing this : auxiliary = auxiliary->proximo and auxiliary->proximo = auxiliary->proximo ?
– Snow
there is a lot of difference yes. The second form is a tautology. Basically you are doing
var = varin this second way, which is the same thing as doing nothing. Maybe you still fall into an illegal access memory, which would cause asegmentation fault. For example ofauxiliar->auxiliarbe worthNULL– Jefferson Quesado
I will formalize the comment just for questions to have the question answered
