一个显示出现次数的程序，为什么输入数字显示的不对啊，想不出来了

/*输出范例：
Enter a number: 41271092
Digit:    0    1    2    3    4    5    6    7    8    9
Occurrences:    1    2    2    0    1    0    0    1    0    1
*/
#include<stdio.h>
int main(){
    printf("Enter a number: ");
    char str[10];
    scanf("%s",&str);
    
    int i,p;
    int x0=0,x1=0,x2=0,x3=0,x4=0,x5=0,x6=0,x7=0,x8=0,x9=0;
    for (i=0;i<10;i++){
        p=str[i];
        switch(p){
            case 0: x0=x0+1; break;
            case 1: x1=x1+1; break;
            case 2: x2=x2+1; break;
            case 3: x3=x3+1; break;
            case 4: x4=x4+1; break;
            case 5: x5=x5+1; break;

        }
    }

这到底是为什么呢，输出的东西一直都是一样的。。。。
