Hi,
I have a problem with sturcts.
I have something like :
I want to create structs as user request.Code:struct stack1 { int number; struct stack1 *next; };
I mean, i`ll get some number from the user input, and create this number of startcts.
For example, i got the number 3 from the user.
Automaticly create :
stack1 s1; stack1 s2; stack1 s3; ( 3 structs ).
I dont care the structs names.
I hope the explanation was clear, Thanks for helpers.
Or.
Create a dynamic array of struct stack1.

Not really. Are you trying to create a linked list of structures? If that is the case take a look at this tutorial. If you are just trying to dynamically allocate an array of structures you would need something like this:
EDIT: Of course you would check the return value of malloc to ensure you actually got the memory you requested.Code:#include <stdio.h> #include <stdlib.h> struct myStruct{ int i; }; int main(void){ struct myStruct *ptrStruct = malloc(2*sizeof(myStruct)); ptrStruct[0].i = 3; ptrStruct[1].i = 4; for(int i=0;i<2;i++) printf("%d\n", ptrStruct[i].i); getchar(); return(0); }
