Hi everyone,

I'm trying to find the maximum and minimum values in a C array, but I'm running into a problem. My code calculates the maximum value correctly, but the minimum value is always a very large negative number, even when all the values in the array are positive.

I've tried initializing the min variable to a large positive number, but it doesn't seem to help.

Here's my code:

#include <stdio.h>

int main(void)
{
    int i, sum = 0;
    int numbers [5];
    int min, max, average;
    
    printf("enter 5 numbers:\n");
    
    for (i = 0; i < 5; i++)
    {
        scanf("%d", &numbers[i]);
        sum += numbers[i];
    }
    
    max = numbers[i];
    min = numbers[i];
    
    for (i = 0; i < 5 ; i++)
    {
        if (numbers[i] > max)
        {
            max = numbers[i];
        }
        if (numbers[i] < min)
        {
            min = numbers[i];
        }
        
    }
    
    average = (double)sum/5;
    
    printf("Average is %d and sum is %d\n", average, sum);
    printf("Max number is %d and the min number is %d\n", max, min);
    
}

Can anyone help me figure out what's going wrong?

Thanks!

So I made a function to determine the maximum element of an array of integers. But when I try to print the value of the maximum element, it gives me a weird large number 1619117764., and isn't what I'm expecting. What am I doing wrong? Thank you so much in advance.

This is the error message:

C:\Users\USER\Desktop\Discrete Math\Max Value.c|25|warning: passing argument 1 of 'max_value' makes pointer from integer without a cast [-Wint-conversion]|

Here is my code:

#include <stdio.h>

int max_value (int input[])
{
 int size=10, max;
 max=input[0];

 for(int i=1;i<size;i++)
 {
     if(max<input[i])
     {
         max = input[i];
     }
 }

 return max;
}


int main ()
{
    int x, max;
    int input[] = {2, 3, 5, 10, 15, 42, 28, 88, 92};

    x = max_value(max);
    printf("/n The Max is: %d" ,x);

    return 0;
}
