C program to find maximum and minimum element in array

Find maximum and minimum element in array


Write a C program to find maximum and minimum element in array.¬†Here’s simple program to find maximum and minimum element in array in C Programming Language.


What is an Array ?


Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

Instead of declaring individual variables, such as number0, number1, …, and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and …, numbers[99] to represent individual variables. A specific element in an array is accessed by an index.

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.


Here is source code of the C program to find maximum and minimum element in array. The C program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/*  C program to find maximum and minimum element in array  */

#include <stdio.h>

int main()
{
    int arr[100];
    int i, max, min, size;

    /*
     * Reads size array and elements in the array
     */
    printf("Enter size of the array: ");
    scanf("%d", &size);
    printf("\nEnter %d elements in the array: \n",size);
    for(i=0; i<size; i++)
    {
        printf("\nEnter %d element in the array: ",i+1);
        scanf("%d", &arr[i]);
    }

    /* Supposes the first element as maximum and minimum */
    max = arr[0];
    min = arr[0];

    /*
     * Finds maximum and minimum in all array elements.
     */
    for(i=1; i<size; i++)
    {
        /* If current element of array is greater than max */
        if(arr[i]>max)
        {
            max = arr[i];
        }

        /* If current element of array is smaller than min */
        if(arr[i]<min)
        {
            min = arr[i];
        }
    }

    /*
     * Prints the maximum and minimum element
     */
    printf("\nMaximum element = %d\n", max);
    printf("\nMinimum element = %d\n", min);

    return 0;
}

OUTPUT : :


Enter size of the array: 8

Enter 8 elements in the array:

Enter 1 element in the array: 1

Enter 2 element in the array: 4

Enter 3 element in the array: 2

Enter 4 element in the array: 5

Enter 5 element in the array: 8

Enter 6 element in the array: 4

Enter 7 element in the array: 0

Enter 8 element in the array: 6

Maximum element = 8

Minimum element = 0
