Input validation is also known as data validation which is used for validate or test the user input .
The example of input validation in c++ programming
#include <iostream> // header file
using namespace std;
int main() // main function
{
int a1; // variable declarartiomn
cout << "Enter the age: ";
cin >> a1;
if(a1> 18) // validate user input
{
cout << "You are eligible for vote :";
}
return 0;

Answer:
def letter_grade(grades):
letters = []
for grade in grades:
if grade >= 90 and grade <= 100:
grade = 'A'
elif grade >=80 and grade <= 89:
grade = 'B'
elif grade >=70 and grade <= 79:
grade = 'C'
elif grade >=60 and grade <= 69:
grade = 'D'
else:
grade = 'F'
letters.append(grade)
return letters
lst = [100, 20, 75, 81]
print(letter_grade(lst))
Explanation:
Create a function called letter_grade that takes one parameter, grades
Create an empty list, letters, to hold the letter grades
Initialize a for loop iterates through the grades. Check each grade, find its convenient letter and put it in the letters.
When the loop is done, return the letters.
Call the function with given list and print the result
