Please post your code so far.
You can use an entry widget for both input and output, but the user will be forced to manually clear the widget before entering new text, otherwise your pre-entered text may become part of the input.
It would be better to use two separate widgets, one for display of the question, a Text, or label widget for example, and then an entry widget for the input.
These can be oriented side by side for a good presentation.

This is my code:-
import sqlite3
from tkinter import *
from tkinter import messagebox
def enter():
root.geometry('650x850')
conn = sqlite3.connect('ceregister.db')
c = conn.cursor()
c.execute("SELECT name FROM register")
table=c.fetchall()
for i in range(len(table)): #Rows
#for j in range(width): #Columns
b = Entry(root)
b.grid(row=7+i, column=0)
b.insert(0,table[i])
b.configure(state='disabled')
c = Entry(root)
c.grid(row=7+i,column=1,sticky=W)
conn.close()
root=Tk()
root.geometry('500x300')
root.title("CE Maker Vr. 2021")
lblname=Label(root,text="Name of the Teacher: ")
lblname.grid(row=0,column=0,pady=20)
lblsubject=Label(root,text="Subject: ")
lblsubject.grid(row=1,column=0,sticky=E)
txtteacher=Text(root,width=25,height=1)
txtteacher.grid(row=0,column=1)
txtsubject=Text(root,width=25,height=1)
txtsubject.grid(row=1,column=1)
lblclass=Label(root,text="Class: ")
lblclass.grid(row=2,column=0,pady=20,sticky=E)
#btnsave=Button(root,text="Save Marks",command=savemark)
#btnsave.grid(row=0,column=3)
btnenter=Button(root,text="Enter CE Marks", command=enter)
btnenter.grid(row=3,column=1,columnspan=2,sticky=EW)
root.mainloop()
