I'm still learning, but I made this. The color input isn't
validated for random strings characters (will get a seg
fault). Still need to add the calculations

#include <stdio.h>
#include <string.h>
#include <ctype.h>


void colors() {

int ctr = 0;
double price;
char color[20], tmp[20];
char colorMenu[9][20] = {" ", "WHITE", "BLACK", "RED",
"GREEN", "BLUE", "ORANGE", "YELLOW", "PURPLE"};
int discount[9]= { 0, 15, 20, 25, 30, 35, 40, 45, 50 };

do {
printf("\n\nEnter the discount sticker color -> ");
fgets(tmp, 20, stdin);
sscanf(tmp, "%s", &color);
} while (isalpha(color[1]) == 0);

do {
printf("\n\nEnter the price -> ");
fgets(tmp, 20, stdin);
} while (sscanf(tmp, "%f", &price) == 0);

for (int x = 0; color[x] != '\0'; x++)
color[x] = toupper(color[x]);

for (ctr = 0; (strcmp(color, colorMenu[ctr]) != 0); ctr++);

printf("\nPICK: %d", ctr);
printf("\nYOU CHOSE: %s, DISCOUNT: %d percent off",
colorMenu[ctr], discount[ctr]);

}

int main() {

colors();

return (0);
}
