    int n;
    printf("Enter the energy in watts: ");
    scanf("%d",&n);
    if(n>=0&& n<=50){
        double price=n*2.25;
        printf("Total price is: %.2f",price);
    }
    else if(n>50&& n<=100){
        double price=n*4.51;
        printf("Total price is: %.2f",price);
    }
    else if(n>100&& n<=200){
