Thread: new to c ...please help

hello
first my code

Code:

void delayMessage(){
     char delay;
     
     printf("\n Please press enter to return to the main menu\n");
     
     scanf("%c",delay);
     }

ok so i want this function to take in enter and that is all.........i just do not know how to do it

its just a delay message

Code:

void viewBooks(){
 printf("Displaying all books...\n");
 for(int i = 0; i< count;i++){
     
    // printf("%d. Bookname %s \n Book Serial %ld\n",i+1,books[i].title,&books[i].serial);
  printf("Book name : %s \n",books[i].title );
  printf("Book Serial: %ld \n",books[i].serial);
  printf("Authors name : %s \n",books[i].author );
  printf("Book year %d\n",books[i].yearOfPublication);
  }
  delayMessage();
     }

this is where i call the function


and this is my main method

Code:

int main(){
    char delay;
    int numSelected,i;
    
    

 do{
  runMainMenu();
  scanf("%d",&numSelected);
 switch(numSelected){
  
 case 1: addBook(); break;
  case 2: deleteBook(); break;
  case 3: viewBooks(); break;
  case 4: viewABook(); break;
  case 5: printf(" "); break;

  }
 }while(numSelected != 5);


    
    return 0;
}

when i select the number 3 it shows the books and the mainmenu comes back.....
the delay message should come up after showing the boook details

i had that in already....and i just treid it agian...smae thing still happens

it displays the books and then the message but does not scan

but right now i realised what was wrong

and now im happy

i put a fflush(stdin);

and now it works fine

cheers for the brain storming!!!!

Code:

void delayMessage(){
     char delay;
     
     printf("\n Please press enter to return to the main menu\n");
     fflush(stdin);
     scanf("%c",&delay);
     }
