C program to find smallest and largest number in an array

C program to find largest and smallest number in an array

In this tutorial, we will discuss the concept of a C program to find the largest and smallest number in an array

In this topic, we learn how to find the smallest and largest element of an array(Collection of elements)

This program gets “n” number of elements and Enter the elements of the array as input from the user. then, this program finds and displays the smallest and largest elements from the array using for loops.

Java program to find largest and smallest number in an array

In this programs, we can see step by step procedure for completion of the program.

Declare an array of fixed capacity
Essential variable declaration
Taking the size of the array as input from the user
Taking the elements of the array as input from the user
loop for find the smallest and largest value
Display result on the screen

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int arr[30];//array declaration
    int length,i;
    int min,max; //essential variable declaration
    printf("Enter the length of the array: ");
    scanf("%d", &length);//get input from user for length
    for(i=0; i<length; i++){
    printf("Enter element %d: ",i+1);//enter elements for array
    scanf("%d", &arr[i]);
    }
    max=arr[0];//assume first element as largest number
      min=arr[0];//assume first element as smallest number

    for(i=0; i<length; i++){//iterate for loop from first index of array
    if(max<arr[i]){
        max=arr[i];
    }
    if(min>arr[i]){
        min=arr[i];
    }
    }
    printf("\nLargest elements is: %d",max);
    printf("\nSmallest elements is: %d",min);
getch();//display result on the screen
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter the length of the array: 5
Enter elements 1: 45
Enter elements 2: 12
Enter elements 3: 98
Enter elements 4: 65
Enter elements 5: 34

Largest elements is: 98
Smallest elements is: 12
