To define structure in C we use struct keyword.
Using structure we can form different groups according to their specialty.
Syntax of defining an structure are given below:
struct tag_name {
  type member_name;
  type member_name;
  type member_name;
} structure_name = {initializer_values};
Example of an structure:

#include  
#include  int main(void); 
int main()
{
int i;
struct
{
   char szSaying[129];
   int nLength;
} MySaying = {�Firestone�s Law of Forecasting:�,
strlen(MySaying.szSaying)};
printf(�sizeof(MYSaying)=%d\n�, sizeof(MySaying));
printf(�MySaying %p%3d�%s�\n�, &MySaying.szSaying,
MySaying.nLength, MySaying.szSaying);
printf(�\n\n�);
return (0);
}
