포인터, 파일 및 함수에 대한 도움이 C

Question

내가 Dev-C++를 사용하면서 컴파일 할 때 3 개의 오류가 발생합니다.

#include <stdio.h> 
#include <conio.h> 
#include <stdlib.h> 
#include <string.h> 

struct agenda{ 
    char nombre [50]; 
    char telefono[25]; 
    char email[50]; 
    } 
    struct nodo{ 
     struct agenda dato; 
     struct nodo *proximo;  
     } 

    struct nodo *nuevonodo 
      int colavacia(struct nodo *) 
    struct nodo *creacola (struct nodo *, struct agenda); 

    void mostrar (struct nodo *); 

    void main() 
    { 
     struct nodo *pri=NULL, *ult=NULL; 
     struct agenda x; 

     printf ("ingrese nombre: "); 
     gets(x.nombre); 
     while (strcmpi(x.nombre, "fin")) 

    { 
     printf ("ingrese telefono: "); 
     gets (x.telefono); 
     printf ("ingrese mail: "); 
     gets(x.mail); 
     ult=creacola(ult,x); 
     if (pri==NULL) pri=ult; //si es la 1 pasada pongo en pri el valor del primer nodo 
     printf ("ingrese nombre: "); 
     gets(x.nombre); 
    } 
    if (colavacia(pri)==1) 
    { 
    printf ("No se ingresaron registros");getch(); 
    } 
    else mostrar(pri); 

    } 
    struct nodo *nuevonodo() 
    { 
     struct nodo *p; 
     p=(struct nodo *)malloc(sizeof(struc nodo)); 
     if(p==NULL) 
     { 
      printf ("memoria ram llena"); 
      getch(); 
      exit(0); 
     } 
     return p; 
    } 

    struct nodo *creacola(struct nodo *ult, struct agenda x) 
    { 
     struct nodo *p; 
     p=nuevonodo(); 
     (*P).dato=x; 
     (*p).proximo=NULL; 
     if(ult!=NULL) (*ult).proximo=p; //si hay nodo anterior en prox pongo la direccion del nodo actual 
     return p; 
    } 

    int colavacia(struct nodo *pri) 
    { 
     if(pri==NULL) return 1; 
     else 
     return 0; 
    } 

    void mostrar (struct nodo *pri) 
    { 
     struct nodo *aux; 

    while(pri!=NULL) 
    { 
     printf("Nombre: %s - telefono: %s - Mail: %s \n", 
     pri->dato.nombre,pri->dato.telefono,pri->dato.mail); 
     aux=pri; 
     pri=(*pri).proximo; 
     free(aux); 
    } 
    getch(); 
} 

Answer 1

세미콜론으로 struct 정의를 종료해야합니다

변수 및 함수 선언에 대한 유사

struct agenda{ 
    char nombre [50]; 
    char telefono[25]; 
    char email[50]; 
}; // <- HERE 

:

struct nodo *nuevonodo; 
int colavacia(struct nodo *); 

그리고 main의 반환 값이 int을 입력합니다.
