Stricture of Variable Function to C Programe

Program passing structure to function in C by value

#include 

#include

#include 

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);

}

Output

Id is: 1

Name is: Raju

Percentage is: 86.500000

Passing structure to function in C by address

#include 

#include

#include 

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);

}

Output

Id is: 1

Name is: Raju

Percentage is: 86.500000

Structure variable as global in C Program

#include 

#include 

#include 

struct student 

{

            int id;

            char name[20];

            float percentage;

};

struct student record; 

void structure_demo();

int main() 

{

            record.id=1;

            strcpy(record.name, "Raju");

            record.percentage = 86.5;

            structure_demo();

            return 0;

}

void structure_demo()

{

            printf(" Id is: %d \n", record.id);

            printf(" Name is: %s \n", record.name);

            printf(" Percentage is: %f \n", record.percentage);

}

Output

Id is: 1

Name is: Raju

Percentage is: 86.500000
