please help!! some of the testcases are failing and i dont know why.

Here is the question:

Write a program in C++.Prompt the user for his/her first name. Output the user's nickname. Use this algorithm to generate a nickname:

If the first letter in the user's name is odd according to the ASCII chart, output "Big" followed by the first three letters of the name.

If the first letter in the user's name is even according to the ASCII chart, output "Lil" followed by the first four letters of the name.

Here is my code:

#include #include using namespace std; //Returns true if the given string only contains letters

//Returns false otherwise

bool verify(string name)

{

//assume that all characters in the string are letters

bool valid_string = true;

for(int subscript = 0; subscript < name.length(); subscript++)

{

if (isdigit(name[subscript]))//if (the current character is a digit)

valid_string = false;//this string is no longer valid

else if(ispunct(name[subscript]))//if (the current character is a punct)

valid_string = false;//this string is no longer valid

}

//go back to where we left off -- bring the result

return valid_string; } int main() { string name; cout << "Enter your first name" << endl; cin >> name; if (verify(name)) { cout << "Your nickname is:" <
