指针操作一维数组

eg1.

int myarray2(){
    int array[5] = {'a','b','c','d','e'};
    int *p = array;
    printf("[p]:%c\n",*p+4);
    int i = 0;
    
    for (;i<5; i++) {
        
        for (int j= i; j<5; j++) {
            if(*(p+i) < *(p+j)){
            int tmp = *(p+i);
            *(p+i) = *(p+j);
            *(p+j) = tmp;
            }
        }
        printf("[%d]:%p,%c\n",i,*(p+i),*(p+i));
    }
    return 0;
}
output:
[p]:e
[0]:0x65,e
[1]:0x64,d
[2]:0x63,c
[3]:0x62,b
[4]:0x61,a
