1 In some situations a typedef can be replaced by a #define. Here is an example: typedef float DOLLARS; int main(void) { DOLLARS amount = 100.0, interest = 0.07 = printf("DOLLARS return 0; 0.07 amount; %.2f\n", amount + interest); } Execute this program so you understand its effects, then replace the typedef by #define DOLLARS float

Exercises 1 In some situations a typedef can be replaced by a #define. Here is an example: typedef float DOLLARS; int main(void) { DOLLARS printf("DOLLARS return 0; } amount = 100.0, interest } Execute this program so you understand its effects, then replace the typedef by { = #define DOLLARS float When you recompile the program and execute it, does it behave as it did before? 2 In some situations a typedef cannot be replaced by a #define. Consider the fol- lowing program: typedef float DOLLARS; int main(void) DOLLARS return 0; %.2f\n", amount + interest); #define float DOLLARS; DOLLARS = amount + interest; printf("DOLLARS amount = 100.00, interest 0.07 amount; 0.07 amount; = %.2f\n", DOLLARS); Execute this program so that you understand its effects. If the typedef is replaced by the line DOLLARS float /* new block */
