In C, we use typedef to create aliases for already existing types. For structure, we can define a new name that can be used in place of the original struct name. In this article, we will learn how to create a typedef for a structure in C++. Use the typedef struct in CTo create an alias for a structure in C, we can use the typedef keyword typedef for a structure that provides the existing datatype with a new name. SyntaxFor defining the structure and creating a typedef simultaneously use: typedef struct StructName { // Member definitions} TypedefName;For defining the Structure first, then creating a typedef use: struct StructName { // Member definitions};typedef struct StructName TypedefName; C Program to Create an Alias Using typedef for a structThe below program demonstrates the use typedef keyword to create a typedef for a structure in C. C
// C program to create a typedef for a structure #include // Defining the structure struct Student { char name[50]; int age; float gpa; }; // Creating a typedef for the struct typedef struct Student St; int main() { // Declaring a variable using the typedef St student1; // Assigning values to the struct members snprintf(student1.name, sizeof(student1.name), "Ram"); student1.age = 20; student1.gpa = 9.5; // Displaying the information of a student printf("Student Information:\n"); printf("Name: %s\n", student1.name); printf("Age: %d\n", student1.age); printf("GPA: %.2f\n", student1.gpa); return 0; } Output Student Information: Name: Ram Age: 20 GPA: 9.50
