顯示字符串，而不是在printf的數字（C）

Question

我有了這個代碼用C寫的，只是對某些號碼會顯示一條消息

int main(void) { 
int a, d;  
d = scanf("%d", &a); 
switch(a){ 
    case 1: 
     printf("ml' nob:\n%d\nQapla'\nnoH QapmeH wo' Qaw'lu'chugh yay chavbe'lu' 'ej wo' choqmeH may' DoHlu'chugh lujbe'lu'.\n", a); 
     break; 
    case 2: 
     printf("ml' nob:\n%d\nQapla'\nQu' buSHa'chugh SuvwI', batlhHa' vangchugh, qoj matlhHa'chugh, pagh ghaH SuvwI''e'.\n",a); 
     break; 
    case 3: 
     printf("ml' nob:\n%d\nQapla'\nqaStaHvIS wa' ram loS SaD Hugh SIjlaH qetbogh loD.\n",a); 
     break; 
    case 4: 
     printf("ml' nob:\n%d\nQapla'\nHa'DIbaH DaSop 'e' DaHechbe'chugh yIHoHQo'.\n",a); 
     break; 
    case 5: 
     printf("ml' nob:\n%d\nQapla'\nleghlaHchu'be'chugh mIn lo'laHbe' taj jej.\n",a); 
     break; 
    default: 
     printf("ml' nob:\n%d\nluj\n", a); 
     break; 
} 
return 0;} 

但是當我輸入輸入字符串或字符它給了我很多無意義的數字。有沒有辦法顯示我輸入的字符串，而不是數字。

編輯： 輸入

abc 

輸出

What i want : abc 
What it shows: 3469312

試試這個..！

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

#include <stdio.h> 
using namespace std; 
int main(void) { 
    int a, d; 
    char str[10]; 
    scanf("%s", &str); 

    char* err = NULL; 
    a = strtol(str, &err,10); 
    if (err==NULL) //Conversion Error 
     a = -1; 

    switch((int)a){ 
    case 1: 
     printf("ml' nob:\n%d\nQapla'\nnoH QapmeH wo' Qaw'lu'chugh yay chavbe'lu' 'ej wo' choqmeH may' DoHlu'chugh lujbe'lu'.\n", a); 
     break; 
    case 2: 
     printf("ml' nob:\n%d\nQapla'\nQu' buSHa'chugh SuvwI', batlhHa' vangchugh, qoj matlhHa'chugh, pagh ghaH SuvwI''e'.\n",a); 
     break; 
    case 3: 
     printf("ml' nob:\n%d\nQapla'\nqaStaHvIS wa' ram loS SaD Hugh SIjlaH qetbogh loD.\n",a); 
     break; 
    case 4: 
     printf("ml' nob:\n%d\nQapla'\nHa'DIbaH DaSop 'e' DaHechbe'chugh yIHoHQo'.\n",a); 
     break; 
    case 5: 
     printf("ml' nob:\n%d\nQapla'\nleghlaHchu'be'chugh mIn lo'laHbe' taj jej.\n",a); 
     break; 
    default: 
     printf("ml' nob:\n%s\nluj\n", str); 
     break; 
    } 
    return 0;}
