Basic example showing constants usage in C #include /*constants for bonus rates and sales*/ #define BONUSRATE1 0.1 #define BONUSRATE2 0.15 #define BONUSRATE3 0.2 #define SALES1 2000 #define SALES2 5000 #define SALES3 10000 int main() { int sales; double commission; /*get employees sales*/ printf("Please enter your total sales to the nearest dollar.\n"); scanf("%d", &sales); /*calculate employees bonus based on info*/ if(sales <=2000) { commission = sales * BONUSRATE1; printf("%g\n" , commission); } else if(sales > 2000 && sales <=5000) { commission = sales * BONUSRATE2; printf("%g\n" , commission); } else { commission = sales * BONUSRATE3; printf("%g\n" , commission); } return 0; }
