假设整数数组 a 中，存在与整数 x 相同的数据，x 为用户输入，返回最后一个与x相同的元素的下标
这个数组是自己输入的吗，如果不是那怎么有数据，，刚学不是太会，最好能给出代码，谢谢各位大佬

程序代码：#include <stdio.h>
int main(void)
{
int a[10] = {0, 1, 2, 3, 3, 5, 6, 7, 8, 3};
int b = 0;
printf("Please you input the number: ");
scanf("%d", &b);
int length = sizeof(a)/sizeof(int);
for(size_t i = 0, j = 0; i != length; ++i){
if(b == a[i]){
++j;
printf("The number of %d times it appears in the array is %d\n", j, i+1);
}
}
return 0;
