Switch Statements: Multi-Way Branching
A switch statement provides an elegant way to handle multiple conditions based on a single variable's value. It evaluates the expression once and jumps to the matching case label. The break keyword prevents fall-through to subsequent cases.

#include <iostream>int main() {int grade = 2;switch (grade) {case 1:std::cout << "Excellent!" << std::endl;break;case 2:std::cout << "Good job!" << std::endl;break;case 3:std::cout << "Satisfactory" << std::endl;break;default:std::cout << "Needs improvement" << std::endl;}return 0;}
Breakdown
1
switch (grade) {
Begins switch statement, evaluates the grade variable
2
case 1:
Label for when grade equals 1
3
std::cout << "Excellent!" << std::endl;
Output executed when case 1 matches
4
break;
Exits the switch block, preventing fall-through
5
default:
Executed when no case matches the value
