How can I fix this custom dice roll program to work correctly?

[conman2495]

I need to write a program that will prompt the user to input a number-sided dice and a number of rolls, and then it will output all of the rolls in a sequence. The program I have written will get the number of rolls correct, but something goes wrong with the number-sided dice. It will output numbers in the 100s for a 6-sided dice. Here's my code, does anyone know how to fix this? (My 'y' integer is the one for the number sided die).

#include <stdio.h> 
#include <time.h> 
int rolldie(); 

int main(){ 
int x, n;
double y;
printf ("What sided dice do you want to roll?... %d");
scanf ("%d", &y);
printf("How Many Rolls do You Want?... %d");
scanf("%d", &n);    
srand(time(0));
for(x=0;x<n;x++) 
printf("%d ",rolldie()); 
return 0; 
} 
int rolldie(){ 
return 1 + rand() %'y' ; 
}

I'm surprised you're not getting compiler errors and warnings.

1. The printf calls on lines 8 and 10 each include %d, but do not pass a corresponding argument.
2. Line 9 uses %d to scanf a value for y, but y is a double. %d is only for ints.
3. Line 18 in rolldie() references y, but y is not defined within the scope of that function.
4. Line 18 says "... % y", but the % modulo operator only works properly with integer operands.
5. lLine 18 says 'y' (note the single quotes). This is the character constant lower-case-y, not the value of a variable.
