Calculator (Switch)

Calculator Program using Switch Case in Java

A simple calculator that uses switch case to pick the operation.

Java Program

int a = 10, b = 5; char op = '*';
switch (op) {
    case '+': System.out.println(a + b); break;
    case '-': System.out.println(a - b); break;
    case '*': System.out.println(a * b); break;
    case '/': System.out.println(b != 0 ? a / b : "Cannot divide"); break;
    default: System.out.println("Invalid");
}

Output

50

How it Works

  • switch selects the operation based on the operator character.
  • Division checks for divide-by-zero first.

Summary

कैसे काम करता है

  • switch operator character के आधार पर operation चुनता है।
