Structures – Theory and Programs [Learn to code]

What are Structures? Learn syntax for Structures and different programs on Structures.

• 095. Define a structure Employee having elements emp_id, name,etc. Accept data and reprint it

  #include<stdio.h>
  #include<conio.h>  
  
  struct Employee
  {
   char name;
   int emp_id;
   long phone_no;
  };
  
  main()
  {
  	struct Employee e;
  	clrscr();
  	printf("Enter name : ");
  	scanf("%s",&e.name);
  	printf("Enter emp_id: ");
  	scanf("%d",&e.emp_id);
  	printf("Enter Phone Number: ");
  	scanf("%ld",&e.phone_no);
  
  	printf("\n\nEnter name : %s",e.name);
  	printf("\n\nEnter Emp Id       : %d",e.emp_id);
  	printf("\n\nEnter Phone Number : %ld ",e.phone_no);
  
  	getch();
  }
  
  
  

• 096. Define a structure Student having fields roll_no, name, marks, etc, for 5 students, accept data and reprint

  
  #include<stdio.h>
  #include<conio.h>  
  
  struct Student
  {
   char name;
   int roll_no;
   int m1,m2,m3;
  };
  
  main()
  {   int i;
  	struct Student s;
  	clrscr();
  	for(i=0;i<5;i++)
  	{   printf("\nEnter data for Student %d.....\n",i+1);
  		printf("Enter name           : ");
  		scanf("%s",&s.name);
  		printf("Enter Roll No.       : ");
  		scanf("%d",&s.roll_no);
  		printf("Enter marks for sub1 : ");
  		scanf("%d",&s.m1);
  		printf("Enter marks for sub2 : ");
  		scanf("%d",&s.m2);
  		printf("Enter marks for sub3 : ");
  		scanf("%d",&s.m3);
  	}
  
  	for(i=0;i<5;i++)
  	{   printf("\nStudent   %d\n",i+1);
  		printf("Name    : %s\n",s.name);
  		printf("Roll No.: %d\n",s.roll_no);
  		printf("Sub1    : %d\n",s.m1);
  		printf("Sub2    : %d\n",s.m2);
  		printf("Sub3    : %d\n",s.m3);
  	}
  
  	getch();
  }
  
  
  

• 097. Define a structure Employee having elements emp_id, name, DOB, DOJ etc. Accept data and reprint it. (use structure within structure)

  #include<stdio.h>
  #include<conio.h>  
  
  struct Date
  {
  	int mm,dd,yy;
  };
  
  struct Employee
  {
  char name;
   int emp_id;
   struct Date DOB,DOJ;
  };
  
  main()
  {   int i;
  	struct Employee e;
  	clrscr();
  		printf("\nEnter name           : ");
  		scanf("%s",&e.name);
  		printf("\nEnter emp_id.        : ");
  		scanf("%d",&e.emp_id);
  		printf("\nEnter Date of Joining\n ");
  		printf("(dd-mm-yy) : ");
  		scanf("%d-%d-%d", &e.DOJ.dd,&e.DOJ.mm,&e.DOJ.yy);
  		printf("\nEnter Date of birth\n ");
  		printf("(dd-mm-yy) : ");
  		scanf("%d-%d-%d", &e.DOB.dd,&e.DOB.mm,&e.DOB.yy);
  
  		printf("\nName           : %s",e.name);
  		printf("\nEmployee ID    : %d",e.emp_id);
  		printf("\nEnter DOJ      : %d-%d-%d", e.DOJ.dd,e.DOJ.mm,e.DOJ.yy);
  		printf("\nEnter DOB      : %d-%d-%d", e.DOB.dd,e.DOB.mm,e.DOB.yy);
  
  	getch();
  }
