funciton call in structure in c code example

Example 1: structure and function in c

#include <stdio.h>
#include <string.h>
 
struct student 
{
           int id;
           char name[20];
           float percentage;
};
 
void func(struct student *record);
 
int main() 
{
          struct student record;
 
          record.id=1;
          strcpy(record.name, "Raju");
          record.percentage = 86.5;
 
          func(&record);
          return 0;
}
 
void func(struct student *record)
{
          printf(" Id is: %d \n", record->id);
          printf(" Name is: %s \n", record->name);
          printf(" Percentage is: %f \n", record->percentage);
}
