Proposed exercise
Create a program that asks the user for a string and:
- Replaces all spaces with underscores (storing the result in a new string)
- Removes leading spaces (storing the result in another string)
- Removes trailing spaces (storing the result in another string)
- Replaces all lowercase A by uppercase A (storing the result in another string)
The program must display all the strings it generates.
Output
Solution
using System; class Program { static void Main(string[] args) { Console.Write("Tell a string: "); string Entry = Console.ReadLine(); string result; result = Entry.Replace("a", "A"); Console.WriteLine(result); Console.WriteLine(UppercaseFirst(Entry)); } public static string UppercaseFirst(string s) { return char.ToUpper(s[0]) + s.Substring(1); } }
