STRUCTUR OF UNION

Problem 81: Struct GPA

Create a simple structure named Student that holds the following variables-

i. id (integer)

ii. cgpa (float)

iii. name (string)

Now create an instance of that structure named s1 and scan the values from the user. Finally print the id, cgpa and name which user entered.

Code:

 

    #include<stdio.h> 
 
struct student{
    int id;
    float cgpa;
    char name[20];
};
int main()

{
    struct student s1;
    printf("Enter ID: ");
    scanf("%d",&s1.id);
    printf("Enter CGPA: ");
    scanf("%f",&s1.cgpa);
    printf("Enter Name: ");
    scanf("%s",&s1.name);
    printf("\n**Students Information**\n\n");
    printf("ID: %d\n",s1.id);
    printf("CGPA: %f\n",s1.cgpa);
    printf("Name: %s\n",s1.name);


}

Problem 82: Books

Create a simple structure named Book that holds the following data fields-

i. id (integer)

ii. title (string)

iii. author(string

Now create two structure variables of Book type named book1 and book2. Set the following information for

the books-

For book1:

id: 101

title: C Programming Hand Note

author: Mukla.C

For book2:

id: 102

title: Programming with Fun

author: Joy Billah

Finally, print all the information of the two books.

Code:

 

    #include<stdio.h> 
    #include<stdio.h>
 
struct Book{
    int id;
    char title[50];
    char author[20];
};
int main()

{
    struct Book book1;
    struct Book book2;

    book1.id=101;
    strcpy(book1.title,"C Programming Hand Note");
    strcpy(book1.author,"Mukla.c");

    book2.id=102;
    strcpy(book2.title,"Programming with Fun");
    strcpy(book2.author,"Joy Billah");

    printf("Book1 Information:\n");
    printf("ID: %d\n",book1.id);
    printf("Title: %s\n",book1.title);
    printf("Author: %s\n\n",book1.author);

    printf("Book2 Information:\n");
    printf("ID: %d\n",book2.id);
    printf("Title: %s\n",book2.title);
    printf("Author: %s\n",book2.author);

return 0;
}

Problem 83: Tennis Ball

Create a structure named TanisBall where we have two fields- color (string) and weight (float). Now create a pointer variable of structure TanisBall named myBall. Scan the field values for myBall from user and finally print the information of myBall using that pointer variable myBall.

Code:

 

    #include<stdio.h> 
    #include<stdio.h>
 
struct TanisBall{
    char color[15];
    float weight;

};

int main()
{
    struct TanisBall Ball;
    struct TanisBall *myBall;
    scanf("%f",&Ball.weight);
    scanf("%s",&Ball.color);
    myBall=&Ball;
    printf("%f\n",myBall->weight);
    printf("%s",myBall->color);

return 0;
}

Problem 84: Writer Records

Create a structure named Writer with two fields- name (string) and genre (string). Then create an array of Writer named writerRecords. Insert the following records into the array-

i. name- Mukla.C; genre- Technical

ii. name- Mostasim Billah; genre- Technical

iii. name- Mahady Joy; genre- Technical

Finally, print the records of the array by iterating the array using loop.

Code:

 

    #include<stdio.h> 
    #include<stdio.h>
 
struct Writer{
    char name[20];
    char genre[20];

};

int main()
{

    struct Writer writerRecords[3];
    strcpy(writerRecords[0].name,"Mukla.c");
    strcpy(writerRecords[0].genre,"Technical");
    strcpy(writerRecords[1].name,"Mostasim Billah");
    strcpy(writerRecords[1].genre,"Technical");
    strcpy(writerRecords[2].name,"Mahadi Hasan Joy");
    strcpy(writerRecords[2].genre,"Technical");

    int i;
    for(i=0;i<3;i++)
    {
        printf("%d.\n",i+1);

        printf("%s\n",writerRecords[i].name);
        printf("%s\n",writerRecords[i].genre);
    }

return 0;
}

Problem 85: Product

Create a structure named Product with following two fields-

1. name (string)

2. price (double)

Then create a function named printProductInfo() which takes a parameter of Product type and print the information of that Product. Finally, in main function create a variable of structure Product named myProduct and call the printProductInfo() function passing myProduct as the parameter.

Code:

 

    #include<stdio.h> 
    #include<stdio.h>
 
struct Product{
    char name[15];
    double price;

}myProduct;

void printProductInfo(struct Product p)
{
    printf("Product Name: %s\n",p.name);
    printf("Product Price: %.2lf",p.price);
}



int main()
{


    strcpy(myProduct.name,"Sunsilk");
    myProduct.price=2.00;

    printProductInfo(myProduct);
return 0;
}
