C/Structure/Struct Size
Allocate memory for struct
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
struct address {
char name[400];
char street[400];
char city[400];
char state[30];
char zip[100];
};
int main()
{
struct address *p;
if((p = malloc(sizeof(struct address)))==NULL) {
printf("Allocation Error\n");
exit(1);
}
return p;
}
Get the size of a struct
#include <stdio.h>
struct struct_type {
int i;
char ch;
int *p;
double d;
} s;
int main(void)
{
printf("s_type is %d bytes long", sizeof(struct struct_type));
return 0;
}
