Explanation:

#include <stdio.h>

struct student {

char name[50];

int roll;

float marks;

} s;

int main() {

printf("Enter information:\n");

printf("Enter name: ");

fgets(s.name, sizeof(s.name), stdin);

printf("Enter roll number: ");

scanf("%d", &s.roll);

printf("Enter marks: ");

scanf("%f", &s.marks);

printf("Displaying Information:\n");

printf("Name: ");

printf("%s", s.name);

printf("Roll number: %d\n", s.roll);

printf("Marks: %.1f\n", s.marks);

return 0;

}

Output

Enter information:

Enter name: Jack

Enter roll number: 23

Enter marks: 34.5

Displaying Information:

Name: Jack

Roll number: 23

Marks: 34.5

In this program, a structure student is created. The structure has three members: name (string), roll (integer) and marks (float).

Then, a structure variable s is created to store information and display it on the screen.
