The Structure is a special type of C data type. A structure contains a number of data types grouped together. Structure in C allows multiple data types to be grouped together.
The below mentioned program is to demonstrate structures in C Programming Language.

#include
#include
void main(){
    struct animal{
        int age;
        char name[10];
        char gender;
    }a[10];
    
    int no,i;
    clrscr();
    
    printf("Enter the number of animals: ");
    scanf("%d",&no);
    
    for(i=0;i<no;i++){
        printf("\nEnter the age of animal %d: ", i+1);
        scanf("%d",&a[i].age);
        printf("\nEnter the name of animal %d: ",i+1);
        scanf("%s",&a[i].name);
        printf("\nEnter the gender(M/F) of animal %d: ",i+1);
        scanf("%s",&a[i].gender);
    }
    
    for(i=0;i<no;i++){
        printf("\n%d",a[i].age);
        printf("\t%s",a[i].name);
        printf("\t%c",a[i].gender);
    }
    
    getch();
}

Output:

Enter the number of animals: 2

Enter the age of animal 1: 06

Enter the name of animal 1: Sam

Enter the gender(M/F) of animal 1: M

Enter the age of animal 2: 05

Enter the name of animal 2: Maxie

Enter the gender(M/F) of animal 2: F

6       Sam     M
5       Maxie   F
