这个简单程序错在哪里了

#include <stdio.h>

void reverse(unsigned int[] a, int size) {
    int temp;
    for(int i = 0; i < size/2; i++) {
    temp = a[0];
a[0] = a[size - 1 - i];
a[size - 1 - i] = temp;
    }
}
int main() {
    unsigned int[] a = {1, 2, 3, 4, 5};
    reverse(a, 5);
    for(int i = 0; i < size - 1; i++) {
    printf("%u ", a[i]); 
    }
}

这么简单的一个程序却编译不成功，我看了半天也没看出来哪里错了，郁闷啊！
[解决办法]
数组写法错了吧
int[] a
应该是 int a[] 吧。

帮你修改了下代码， 你看看，可以跑了！

#include <stdio.h>

void reverse(unsigned int a[] , int size) 
{
    unsigned int temp;
    for(int i = 0; i < size/2; i++) {
        temp = a[0];
        a[0] = a[size - 1 - i];  
 
        a[size - 1 - i] = temp;   
    }   
}

int main() 
{
    unsigned int a[] = {1, 2, 3, 4, 5}; 
    int size = 5;
    printf("%d ", size); 
    reverse(a, size);
    for(int i = 0; i < size - 1; i++) {
        printf("%u ", a[i]); 
    }   
}
