顯示時出現鬼影輸出;嵌套鏈表[C]

Question

對於長碼iam仍然是新的c ..它只是發生在我顯示回數據的活動數據總是有1個數據插入，這使得我的程序不響應。

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

struct activity{ 
    int reps, calBurn; 
    char aName[30]; 

    struct activity *ptrnexto; 
}; 

struct activity *newptro, *curptro, *prevptro; 

struct plan { 
    char pName[30], focus; 
    int recWieght; 

    struct plan *ptrnext; 
    struct activity *act; 
}; 

struct plan *headptr, *newptr, *curptr, *prevptr; 

int menu(int num); 
int insertPlan(); 
int displayPlans(); 

int main() 
{ 
    menu(1); 
} 

//菜單FUNC

int menu(int no) 
{ 
    int choice; 
    if (no==0){ 
     return 0; 
    } 
    while(no==1) 
    { 
     system("cls"); 
     printf("\n"); 
     printf("\t\t\t\t Welcome!\n"); 
     printf("\t\t\t Input a new fitness plan\t [1]\n" 
       "\t\t\t View ALL fitness plan\t [5]\n"); 
     printf("\n\t\t\t   -----------\n "); 
     printf("\t\t\t Choice: "); 
     scanf("%d",&choice); 
     fflush(stdin); 
     system("cls"); 
     switch(choice) 
     { 
      case 1: 
      { 
       insertPlan(); 
       break; 
      } 
      case 5: 
      { 
       displayPlans(); 
       return 0; 
       break; 
      } 
      default: 
      { 
       printf("Invalid key entry."); 
       break; 
      } 

     }//end switch 
     printf("\n\tDo you wish to return to menu?\n" 
       "\tYes[1]\t\tNo[0]\n\t"); 
     printf("--> "); 
     scanf("%d",&no); 
     return menu(no); 
    } 
    return 0; 
} 

//插入FUNC

    int pos=0,ch; 
    newptr = (struct plan*)malloc(sizeof(struct plan));

    scanf(" %s",&newptr->pName); 
    printf("\nUpperBody(U)--LowerBody(L)--Abdomen(A)--Stamina(S) \nPlan Focus : ");

這裏是顯示輸出後的輸出從菜單中運行

聲明：我沒有這最後用紅色下劃線的數據輸入。

如何做一個輸入一個笑臉反正..

答案被BLUEPIXY在評論給出：
設置NULL到newptr->act。
