想要计算从数字n到数字m之间（包含n和m）有多少个数字d出现，下列程序哪个能够实现（ ）。
int n,m,res,d;
cin >> n >> m>>d;
for(int i = n+1; i <= m; i++){
int temp = i;
while(temp){
if(temp % 10 == d) res++;
temp /= 10;
}
}
cout << res << endl;
return 0;
int n,m,res,d;
cin >> n >> m>>d;
for(int i = n; i <= m; i++){
int temp = i;
while(temp){
if(temp % 10 = d) res++;
temp /= 10;
}
}
cout << res << endl;
return 0;
int n,m,res=0,d;
cin >> n >> m>>d;
for(int i = n; i <= m; i++){
int temp = i;
while(temp){
if(temp % 10 == d) res++;
temp /= 10;
}
}
cout << res << endl;
return 0
int n,m,res=0,d;
cin >> n >> m>>d;
for(int i = n; i <= m; i++){
while(temp){
if(temp % 10 == d) res++;
temp /= 10;
}
}
cout << res << endl;
return 0;
