Input Problem

I need a little help here please. I'm having the user input integers until EOF is indicated.

So here's my error:

------ Build started: Project: Project10, Configuration: Debug Win32 ------

project10.obj : error LNK2001: unresolved external symbol _array

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========


Here's my code:

Code:

#include <stdio.h>

int size = 0;
int array[];

void userinput(int *array){
	int scanf_return = 0;
	do{
		printf("\nEnter an integer or EOF to terminate: ");
		scanf_return = scanf_s("%d", &array[size++]);
	}
	while (scanf_return != EOF);
}
        
void swap(int *a, int *b){
     int c;
     c=*a;
     *a=*b;
     *b=c;
     }

void usersort(int *array){
     int i;
     for(i=0;i<size-1;i++){
                    if(*(array+i)>*(array+i+1)){
                                swap(array+i,array+i+1);
                                i-=2;
                                }
                    }
     
     }



int findmin(int *array){
    return array[0];
    }

int findmax(int *array){
    return array[size-1];
    }


void printminmax(int min,int max){
     printf("The min is: %d \nThe max is: %d\n", min,max);
     }

void printarray(int *array){
     int i;
     printf("The elements of the sorted array from smallest to largest:\n");
     for(i=0;i<size;i++) {
                         printf("%d\t",array[i]);
                         }
     }

int main(){ 
    
    int min,max;
    userinput(array);
    usersort(array);
    min = findmin(array);
    max = findmax(array);
    printminmax(min,max);
    printarray(array);
}

Your "array" doesn't have a size. It must have a size.
As a side note, remove your global variables and make them local. Just as you pass the array, pass its size as well.

I've set the size to 10 but if I enter "EOF" I get a continuous loop. What else do I need to do to terminate the program?

Thanks!

The string "EOF", when entered at the console, is not the same as the constant EOF that you refer to in your code. EOF is actually a code sent by your OS. You can enter that particular value at the console by pressing Ctrl+D.

Thanks! I got it now! Ctrl Z works wonders!
