- Looping techniques in C#
- Loop statements allow us to execute a statement or a group of statements multiple times. The following are the loops supported by C# - Sr.No. Loop types and descriptions 1while loop When a given condition is true, it repeats a statement or a group of statements. It tests the condition before executing the loop body. 2for loop It executes a series of statements multiple times and abbreviates the code that manages the loop variables. 3do...while loop It is similar to the while statement, except that it tests the condition at the end of the loop body. Using C#, you can also use a foreach loop as shown below - example usingSystem;usingSystem.Collections;classDemo{ &n

- To determine if a string has unique characters, first check that the word in the string matches the next word - for(intj=i+1;j<val.Length;j++){ if(val[i]==val[j] )} If a match is found, it means that the string does not contain unique characters. If no match is found, the string contains all unique characters. If it matches, return false, that is, the unique character is not found -for(intj=i+1;j<val.Length;j++){ if(val[i]==val[j])&a
