C Program for Typedef Data Type and Using Structure

C Program to print sum of number using typedef.

#include <stdio.h> #include<conio.h> void main()  {   typedef int number ; number n1=15, n2=20; int add = n1 + n2; printf("%d", add); getch(); }

Output: Sum=35

C Program to print the value using typedef.

#include <stdio.h>   #include <conio.h>   void main()   {   typedef  int num;   num i,j;   i=30;   j=50;   printf("Value of i is :%d",i);   printf("\nValue of j is :%d",j);   getch();   }

Output: Value of i is :30 Value of j is :50

C Program to print the array list using typedef

#include <stdio.h> #include <conio.h>   typedef int array[5];   int main() { array temp = {10, 20, 30, 40,50}; printf("typedef using an array\n"); for (int i = 0; i < 4; i++)    { printf("%d ", temp[i]);   }   return 0; }

Output: Display array list using typedef 10 20 30 40

C Program to store the name, age, height and weight using structure and typedef function.

#include <stdio.h> #include <conio.h>   typedef struct student   {   char name[20];   int age;   int height; int weight; } std;     void main()   {   std std1;   printf("Enter the details of student : ");   printf("\nEnter the name of the student:");   scanf("%s",& std1.name);   printf("\nEnter the age of student:");   scanf("%d",& std1.age);   printf("\nEnter the height of the student:");   scanf("%s",& std1.height);   printf("\nEnter the weight of the student:");   scanf("%s",& std1.weight);   printf("\n Name of the student is : %s", std1.name);   printf("\n Age of the student is : %d", std1.age);   printf("\n Name of the student is : %s", std1. height);   printf("\n Age of the student is : %d", std1. weight);     getch();   }

Output:- Enter the details of student : Enter the name of the student: Aman Enter the age of student:12 Enter the height of the student:23 Enter the weight of the student:24 Name of the student is : Aman Age of the student is : 12

C Program to store the student record using structure and typedef function.

#include <stdio.h> #include <conio.h> #include <string.h>    typedef struct student  { int rollno; char name[30];  int phone_no;  }std;   void main()  {  std p1, p2, p3; p1.rollno = 1;  strcpy(p1.name,"Ram"); p1.phone_no = 9623443; p2.rollno = 2; strcpy(p2.name,"Shyam"); p2.phone_no = 934567822; p3.rollno = 3; strcpy(p3.name,"Krishna"); p3.phone_no = 934567844; printf("First Student\n"); printf("Roll No : %d\n", p1.rollno); printf("name : %s\n", p1.name); printf("phone_number : %d\n", p1.phone_no); printf("Second Student\n"); printf("Roll_No : %d\n", p2.rollno); printf("name : %s\n", p2.name); printf("phone_number : %d\n", p2.phone_no); printf("Third Student\n"); printf("Roll_No : %d\n", p3.rollno); printf("name : %s\n", p3.name); printf("phone_number : %d\n", p3.phone_no); getch();  }

Output: First Student Roll No : 1 name : Ram phone_number : 9623443 Second Student Roll_No : 2 name : Shyam phone_number : 934567822 Third Student Roll_No : 3 name : Krishna phone_number : 934567844

C program to implement using #define function.

#include <stdio.h> #include<conio.h> #define N 3     void main() {   for (int i = 0; i < N; i++)    { printf("The number is %d \n", i);   }   getch(); }

Output: The number is 0 The number is 1 The number is 2
