Structure-Define structure pointer

Structure pointer

typedef struct {
    
    
    // elem / minval
    int elem[20005];
    int minval[20005];
    // stack
    int elem_top;
    int min_top;
    int cur_min;
} MinStack;

// 定义结构指针
MinStack *m = (MinStack *)malloc(sizeof(MinStack));

// 类似于基本类型的指针声明规则，如int
int *seq = (int *)malloc(sizeof(int)*8);
