If you can't read my code, try converting it here[^]

string inputString = "The quick brown fox jumps over the lazy dog";
char[] chars = new char[inputString.Length];
for (int i = 0; i < inputString.Length; i++)
{
    if (inputString[i] >= 'a' && inputString[i] < 'h') // is it between a and g (lower case only)
        chars[i] = (char)(inputString[i] + 1);         // yes, add 1 to make it the next letter
    else
        chars[i] = inputString[i];                     // no, copy direct to the output buffer
}
Console.WriteLine(chars);
