Here TEST is a struct pointer. Structure contains integer. What can be the right factor for it? The TEST structure is as follows.I am using gcc as compiler.
typedef struct TEST_HELP{
int value;
} *TEST, TEST_NODE;
I'm guessing you have something like:
TEST ptr;
// set ptr to something
ptr->value = 5;
printf( "%ld", ptr ); // expect 5 to be printed
This will not work because printf
doesn't know how to print a TEST_HELP structure. You need to print the data within it:
TEST ptr;
// set ptr to something
ptr->value = 5;
printf( "%ld", (long)ptr->value ); // expect 5 to be printed
You should be using %d
for int
values. %ld
is for long
values, hence the cast.
