Write a C program to illustrate macro with arguments.
#include <stdlib.h>
/* macro with arguments */
#define cube(x) (x * x * x)
#define max(x, y, z) ((x = (x > y ? x : y)) > z ? x : z)
#define sum(x, y, z) (x + y + z)
int main() {
int x, y, z, ch, output;
printf("1. Cube\n2. Biggest of three numbers\n");
printf("3. Sum of 3 numbers\n4. Exit\n");
printf("Enter your choice:");
scanf("%d", &ch);
switch (ch) {
case 1:
printf("Enter your input:");
scanf("%d", &x);
output = cube(x);
break;
case 2:
printf("Enter your value for x, y & z:");
scanf("%d%d%d", &x, &y, &z);
output = max(x,y,z);
break;
case 3:
printf("Enter your value for x, y & z:");
scanf("%d%d%d", &x, &y, &z);
output = sum(x, y, z);
break;
case 4:
exit(0);
default:
printf("You have entered wrong option\n");
break;
}
printf("Output: %d\n", output);
return 0;
}
Output:
jp@jp-VirtualBox:~/$ ./a.out
1. Cube
2. Biggest of three numbers
3. Sum of 3 numbers
4. Exit
Enter your choice:2
Enter your value for x, y & z:100 200 300
Output: 300
