swich c code example

Example 1: switch case in c

// example of switch case statement
#include <stdio.h>

int main() {
    char operator;
    double n1, n2;

    printf("Enter an operator (+, -, *, /): ");
    scanf("%c", &operator);
    printf("Enter two operands: ");
    scanf("%lf %lf",&n1, &n2);

    switch(operator)
    {
        case '+':
            printf("%.1lf + %.1lf = %.1lf",n1, n2, n1+n2);
            break;

        case '-':
            printf("%.1lf - %.1lf = %.1lf",n1, n2, n1-n2);
            break;

        case '*':
            printf("%.1lf * %.1lf = %.1lf",n1, n2, n1*n2);
            break;

        case '/':
            printf("%.1lf / %.1lf = %.1lf",n1, n2, n1/n2);
            break;

        // operator doesn't match any case constant +, -, *, /
        default:
            printf("Error! operator is not correct");
    }

    return 0;
}

Example 2: switch case in

function whatToDrink(time){
    var drink ;
          switch (time) {
            case "morning":
              drink = "Tea";
              break;
            case "evening":
              drink = "Shake";
              break;
            default:
              drink="Water";   
          }
  	return drink;
}
console.log(whatToDrink("morning")) //Tea
console.log(whatToDrink("evening")) //Shake
console.log(whatToDrink("night"))   //Water
console.log(whatToDrink("daytime")) //Water
