A shortcut method for writing menu commands in C

The method of writing menu commands that I learned from the teacher can no longer be switched, and the case is typed one by one

//***********How ​​to write menu commands*********//typedef struct SeqTable* ST;typedef void (*FUNC)(ST); //Function pointer, the internal function parameters are ST typestruct{const char* desc;FUNC func;}acts[] ={{"Exit (destroy)", destroy},{"Display sequence table property", show}, //Whether it is empty or not, whether it is full, the number of elements, the capacity ...{"Insert at the end", push},{"Insert at the specified position", insert},{"delete at the end", pop},{"Remove the element at the specified position", my_remove},{"Delete the specified element", delete},{"update", update},{"Search by element value", find},{"Search by condition", search},{"statistics", count},{"clear", clear}};void menu(void){puts("******test******");int i;for(int i = 0; i < sizeof(acts)/sizeof(acts[0]); i++)printf("***%d.%s\n", i, acts[i].desc);printf(">>>");}void test_seqtable(void){ST st = create_sqrtable(10);while(true){menu();int in = 0;scanf("%d", &in);if(in >= 0 && in < sizeof(acts)/sizeof(acts[0]))acts[in].func(st);elseprintf("Error!\n");}}//********************************************

Write a function like this

void clear(ST st){clear_seqtable(st);show(st);}
