Question

What I want to do is simply initialize a instance of a struct. The struct is defined here:

typedef struct Rectangle 
{
tName Name; /* name of the rectangle */
struct Rectangle * binSon[2];
int Center[2];
int Length[2]; /* distance to the boarder of the rectangle */
int Label;
}Rectangle;

and how I initialized it is like below:

Rectangle * binSon[2];
binSon[0] = NULL;
binSon[1] = NULL;

int Center[2];  
int Length[2];

Center[0] = 0;
Center[1] = 0;
Length[0] = 5;
Length[1] = 5;

Rectangle world = {"World", binSon, Center, Length, 0};

at the last line, when I compile the program, it reports me an warning of:

mx_cif_ds_manager.c:52:2: warning: initialization makes integer from pointer without a cast [enabled by default]
mx_cif_ds_manager.c:52:2: warning: (near initialization for 'world.Name[0]') [enabled by default]
mx_cif_ds_manager.c:52:2: warning: initialization makes integer from pointer without a cast [enabled by default]

mx_cif_ds_manager.c:52:2: warning: (near initialization for 'world.Name[3]') [enabled by default]

Not sure what’s going wrong with this piece of program, and wondering if any one has any idea or suggestion that can help me improve this piece of code. Whats a more gental way to initialize a struct?

Thank you

======UPDATE======

Thank you for your help, but what if I want to use variables to initialize a struct. Do I have to malloc a memory space in this case?

The tName definition is here

typedef char tName[MAX_NAME_LEN + 1];

This should work:

Rectangle world = {"World", {NULL, NULL}, {0, 0}, {5, 5}, 0};
