    question about structure?

    Anyone know why we can't use scanf to initialize strucutre?

    #include <stdio.h>
    #include <stdlib.h>
    int main()
    	struct automobile
    		char make[10];
    		char* model;
    		int number_of_doors;
    		float price;
    	scanf( "%s", car.model); /* can we do this? */
    	printf("%s", car.model);
    	return 0;

    Well model is a pointer, you need to make it point somewhere.
    car.model = malloc( 10 );

    Then you can do as you suggest.

    Ideally, you should use fgets() for reading all input to prevent buffer overflows.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
