Wane ne sifofin jikin sadarwa da C# ke bayarwa?

Question

Accepted Answer

C# yana ba da daidaitaccen sifofin jikin sadarwa — shartnawa (`if`, `switch`), madowar (`for`, `foreach`, `while`), da reshen (`break`, `continue`, `return`) — sannan kuma ingantaccen sabis na zamani kamar jujjuyawar switch da pattern matching da ke ba da damar gajere code.

## Shartnawa

```csharp
if (score >= 90)
    grade = "A";
else if (score >= 80)
    grade = "B";
else
    grade = "F";

// ternary and null-coalescing
string status = age >= 18 ? "adult" : "minor";
string name = input ?? "default";        // ?? — use default if input is null
name ??= "fallback";                      // ??= assign if null
```

## Bayanin switch da jujjuyawar switch ta zamani

```csharp
// traditional switch
switch (day)
{
    case "Sat":
    case "Sun":
        type = "weekend";
        break;                            // break required (no fall-through)
    default:
        type = "weekday";
        break;
}

// switch EXPRESSION (C# 8) — concise, returns a value, with pattern matching
string type = day switch
{
    "Sat" or "Sun" => "weekend",
    _ => "weekday",                        // _ = default
};

// pattern matching in switch
string describe = obj switch
{
    int n when n > 0 => "positive int",
    string s => $"string of length {s.Length}",
    null => "null",
    _ => "other",
};
```

Jujjuyawar switch ta zamani **switch expression** gajere ce (tana ba da damar return, babu `break`), kuma tana goyan bayan powerful **pattern matching** (daidaita nau'i, shartnawa, da sauransu) — babbar haɓaka gida da verbose traditional switch.

## Madowar

```csharp
for (int i = 0; i < 10; i++) { }

foreach (var item in collection) { }      // iterate any IEnumerable

while (condition) { }
do { } while (condition);                  // runs at least once
```

`foreach` (maimaita duk `IEnumerable`) shine idiomatic madowa ga tari.

## Reshen

```csharp
foreach (var item in items)
{
    if (item.Skip) continue;   // next iteration
    if (item.Stop) break;       // exit loop
}
return result;                  // exit method
```
