C Program Example to Initialize Structure Variable

#include <stdio.h>
struct student
{
    char name[50];
    int roll;
    float marks;
};
void main()
{
    struct student s;
    printf("Enter information of students:\n\n");
    printf("Enter name: ");
    scanf("%s",s.name);
    printf("Enter Roll Number: ");
    scanf("%d",&s.roll);
    printf("Enter Marks: ");
    scanf("%f",&s.marks);
    printf("\nPrinting Entered Data: \n");
    printf(" Name: %s\n Roll Number: %d\n Marks: %.2f\n",s.name,s.roll,s.marks);
 }

 OUTPUT:
