Thread: Help needed urgently!

Hi
I have an assignment which requires me to do the following:

Required to write a function that finds an integer in an array and returns
its corresponding index. The function must be called findNumber. It must have FOUR parameters:
 The first parameter is the array to be searched
 The second parameter is the integer to be found within the array
 The third parameter is the size of the array
 The fourth parameter is an integer that indicates whether the array is sorted. A value of 1
means the array is sorted; a value of zero means the array is not sorted.


__________________________________________________ __

Since a function can only return one value(To return the position of a required integer in an array in this instance) I have tried to make use of pointers to try and return a value stating whether the array is sorted or not.

This is my code : (It compiles perfectly but it does not produce any outputs)

Code:

#include <stdio.h>
#define SIZE 10

size_t findNumber(int *sort, const int array[],int key,size_t size);

int main(void){
    int a[SIZE];
    size_t x;
    int search_key;
    size_t element;
    int isSorted=0;

   

    for (x = 0;x < SIZE; ++x){
        a[x]=2*x;
    }

    puts("Enter the integer you are looking for:");
    scanf_s("%d", &search_key);

    element= findNumber(&isSorted,a,search_key,SIZE);
   
    if (isSorted==1) {
                   printf("Array is sorted");
    }
    else{
        printf("Array is not sorted");
    }
                       
                  

    printf("Your value has been found in element %d  \n",element);

   

    return 0;
   

}

size_t findNumber(int *sort,const int array[],int key,size_t size){
    size_t n;
   

        for (n = 9; n < SIZE; --n){
        if (array[n] >= array[n-1] || array[n] <= array[n-1] ){
            *sort=1; }
               
            *sort=0;
        }
      
        for (n = 0; n < size; ++n) {
        if (array[n] == key) {
            return n;
        }
       
            return -1;
        
    }

}
