C Program to create user‒defined datatype from structure.

/* C Program to create user‒defined datatye */

#include<stdio.h>

#include<conio.h>

void main()

{

/* Local definitions */

typedef struct

{

char name[20];

char gender[2];

int age;

}rec;

rec candidate[2];

int a;

/* Statement */

clrscr();

for(a=0;a<2;a++)

{

printf("Name of the Employee: ");

scanf("%s", candidate[a].name);

printf("Gender: ");

scanf("%s", candidate[a].gender);

printf("Age: ");

scanf("%d", &candidate[a].age);

}

printf("\nName\t Gender\t Age\n");

for(a=0;a<2;a++)

{

printf("%s\t", candidate[a].name);

printf("%s\t", candidate[a].gender);

printf("%d\n", candidate[a].age);

}

getch();

} /* main */

OUTPUT

Name of the Employee: Mahi

Gender: m

Age: 20

Name of the Employee: Suma

Gender: f

Age: 25

Name Gender Age

Mahi m 20

Suma f 25

EXPLANATION: In the above program, user‒defined data type rec is created using typedef statement. The rec datatype consists of two character and one integer field. An array candidate[2] is declared based on rec datatype. The first for loop and scanf() statement reads data. The second for loop and printf() statement prints the content of array element.
