Question

Wap to input roll name address and mark of 100 student and display them using structure
​

Answer 1

Here's an example program in C that uses structures to input and display information for 100 students:

scss

Copy code

#include <stdio.h>

struct Student {

int roll;

char name[50];

char address[100];

float mark;

};

int main() {

struct Student s[100];

int i;

// Input information for each student

for(i = 0; i < 100; i++) {

printf("Enter information for student %d:\\", i+1);

printf("Roll number: ");

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

printf("Name: ");

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

printf("Address: ");

scanf("%s", s[i].address);

printf("Mark: ");

scanf("%f", &s[i].mark);

}

// Display information for each student

printf("Student Information:\\");

for(i = 0; i < 100; i++) {

printf("Roll number: %d\\", s[i].roll);

printf("Name: %s\\", s[i].name);

printf("Address: %s\\", s[i].address);

printf("Mark: %.2f\\", s[i].mark);

printf("\\");

}

return 0;

}

This program declares a structure called Student that contains fields for roll number, name, address, and mark. It then creates an array of 100 Student structures and uses a loop to input information for each student. Finally, it uses another loop to display the information for each student.
