Standard types are the basic data types that are available in C programming language. They are defined in the <stdio.h> header file. The standard types are:
int: This type is used to store integer values.char: This type is used to store character values.float: This type is used to store floating-point values.double: This type is used to store double precision floating-point values.
You cannot make your own standard types in C programming language. However, you can create your own data types by using structures and unions.
Structures are used to group together related data items into a single unit. Unions are used to store different data types in the same memory location.
Here is an example of how to create a structure to store the name and age of a person:
struct person {
char *name;
int age;
};This structure can be used to store the name and age of a person. The name member is a pointer to a character string, and the age member is an integer.
Here is an example of how to create a union to store a character, an integer, and a floating-point number:
union data {
char c;
int i;
float f;
};This union can be used to store a character, an integer, and a floating-point number. The c member is a character, the i member is an integer, and the f member is a floating-point number.
You can use structures and unions to create your own data types that are more appropriate for your needs. This can make your code more readable and maintainable.
