Make a program that asks for a test score between zero and ten. Show a message if the value is invalid and keep asking until the user enters a valid value
// task-01
#include <iostream>
using namespace std;
int main()
{
int input;
cout << "Enter the test score between 1 and 10:" << endl;
cin >> input;
while (input < 0 || input > 10)
{
cout << "INVALID INPUT:!" << endl;
cout << "Again Enter the test score between 1 nd 10: " << endl;
cin >> input;
}
return 0;
}

Write a program that takes multiple inputs from user until a user enter a negative number. When a negative number is pressed. Program should be terminated and the sum of all positive integars should be displayed to user.
#include <iostream>
using namespace std;
int main()
{
int num;
int sum = 0;
while (num >= 0)
{
cout << "Enter a number :" << endl;
cin >> num;
if (num >= 0)

cout << "The sum of all the above positive numbers = " << sum << endl;

cout << "_______________________________________" << endl;

Write a program which counts number of vowels in a given string and tell every index where a vowel is found. You must have to perform this task using while loop and switch cases. (10 marks) Hint: Use String manipulations concepts here to get value from user and to initialize size.
#include <iostream>
using namespace std;
int main()
{
int size = 100;
char ch[size];
cout << "Enter the string :" << endl;
cin.getline(ch, size);
int n = 0;
int i = 0;
while (ch[i] != '\0')
{
switch (ch[i])
{
case 'a':
{
cout << "The vowel " << ch[i] << " is present at " << i << " index ." << endl;
n++;
break;

case 'e':
{
cout << "The vowel " << ch[i] << " is present at " << i << " index ." << endl;
