percentage and retrieve student information using roll no. in SQLite databases.

Answer 1

Answer:

The program is constructed with the examples

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.
