Great! It sounds like you're working on a CA evaluator system for students. Here are some possible steps to help you get started:

1. Define the data structure: Before you start coding, you need to decide how you will store the student CA details. You could use a database, a file system, or simply a data structure like a list or a dictionary. Depending on the size and complexity of the project, you may want to consider using a database management system like MySQL, PostgreSQL or SQLite.

2. Create a function to add a new record: Write a function that takes inputs like student name, roll number, CA marks, and any other relevant details and adds a new record to your data structure.

3. Create a function to search for a record: Write a function that takes a search query, such as a student name or roll number, and returns all the relevant records that match the query.

4. Create a function to modify a record: Write a function that takes inputs like student name, roll number, and new CA marks, and updates the corresponding record in your data structure.

5. Create a function to delete a record: Write a function that takes a search query, such as a student name or roll number, and deletes all the relevant records that match the query.

6. Create a function to display all records: Write a function that displays all the records in your

Great! Here is an example implementation of a CA evaluator system in C language, with the modules you mentioned:

cCopy code
#include <stdio.h>
#include <string.h>

struct Student {
    char name[50];
    int roll_no;
    float ca_marks;
};

struct Student students[100];  // assuming a maximum of 100 students
int num_students = 0;

// function to add a new student record
void create_record() {
    struct Student new_student;
    printf("Enter student name: ");
    scanf("%s", new_student.name);
    printf("Enter student roll number: ");
    scanf("%d", &new_student.roll_no);
    printf("Enter CA marks: ");
    scanf("%f", &new_student.ca_marks);
    students[num_students++] = new_student;
    printf("Student record added successfully.\n");
}

// function to search for a student record by roll number
void search_record() {
    int roll_no;
    printf("Enter roll number to search for: ");
    scanf("%d", &roll_no);
    int found = 0;
    for (int i = 0; i < num_students; i++) {
        if (students[i].roll_no == roll_no) {
            printf("Student found:\n");
            printf("Name: %s\n", students[i].name);
            printf("Roll number: %d\n", students[i].roll_no);

        printf("No student found with roll number %d\n", roll_no);
    }
}

        if (students[i].roll_no == roll_no) {
            for (int j = i; j < num_students - 1; j++) {
                students[j] = students[j+1];
            }
            num_students--;
            printf("Student record deleted successfully.\n");
            found = 1;
            break;
        }
    }
    if (!found) {
        printf("No student found with roll number %d\n", roll_no);
    }
}

// function to display all student records
void display_records() {
    printf("List of all student records:\n");
    for (int i = 0; i < num_students; i++) {
        printf("Name: %s\n", students[i].name);
