The structure characters of the members does not assignment problem-CodePudding

 # include & lt; stdio.h> 
# include & lt; Stdlib. H> 
Struct c_node {
char data; }; 
Int main () 
{
Struct c_node * head=(c_node *) malloc (sizeof (* head)); 
The head - & gt; Data='https://bbs.csdn.net/topics/g'. 
return 0; 
}

When I debug this simple program, to 8 rows cannot continue to go down, is this why? Hope to have a great god answer!

Struct c_node * head=(c_node *) malloc (sizeof (* head));
Change
Struct c_node * head=(c_node *) malloc (sizeof (c_node));

CodePudding user response:

Struct c_node * head=(struct c_node *) malloc (sizeof (struct c_node));

Int main ()

Struct c_node * head=(c_node *) malloc (sizeof (* head)); 
The head - & gt; Data='https://bbs.csdn.net/topics/g'. 

Printf (" % c \ n ", the head - & gt; The data); 

return 0;
