write a c program to find out the difference between the largest and the smallest element present in an array.  in this blog, we will focus on finding the maximum and minimum quantity in an array and find out their difference

Sample Input and Output

Array is [14,45,85,96,52]

the largest element is 96 and the smallest is 14

and the difference between 96 and 14 is 82

Algorithm to the difference between the largest and smallest element of an array

• Creating an array
• Finding out largest and smallest elements from the array
• Calculating the difference between them
• Print the output

C program to find the difference between the largest and smallest element of an array

#include<stdio.h>
void main(){
    int arr[100],a,i,max,min,diff;
    printf("size of array is:");
    scanf("%d",&a);
    printf("enter the element ");
    for(i=0;i<a;i++){
    scanf("%d",&arr[i]);
    }
    printf("the array is \n");
    for(i=0;i<a;i++){
    printf("%d ",arr[i]);
    }
    printf("\n");
    min= max=arr[0];
    for(i=0;i<a;i++){
        if(max<arr[i]){
            max=arr[i];
        }
    }
    for(i=0;i<a;i++){
        if(min>arr[i]){
            min=arr[i];
        }
    }
    printf("%d is smaller then %d\n",min,max);
    diff=max-min;
    printf("the difference between them is %d",diff);
}

Explanation of the code

Step 1  at first we include library

Step 2 declaring the main method with void as its return type

Step 3 declaring the array and other variables for further use

Step 4 command for user

Step 5  scanf method to take input of the size of the array

Step 6 another command for the user

Step 7, Step 8, Step 9  taking the input according to the size, using the loop, closing the scope of the loop

Step 10, Step 11, Step 12, Step 13 printing the inputted  array using for loop, closing the scope of the loop

Step 14 breaking the line here for our convenience

Step 15  as we created two-variable above min and max, stores the first element of the array

Step 16 for loop to access the element one by one, this loop is for to find the greatest value in the array

Step 17  checking the condition whether the first element is smaller or greater than the  next element

Step 18 if the condition is true then we update the value of the max variable to a new variable which is accessed

Step 19, Step 20  closing both the scopes

Step 21  for loop to access the element once again this loop is for to find the smallest value in the array

Step 22 checking the condition whether the first element is smaller or greater than the  next element

Step 23 if the condition is true then we update the value of the min variable to a new variable which is accessed

Step 24, Step 25 closing both the scopes

Step 26 printing the max and min we a message

Step 27 calculating difference between largest and smallest elements

Step 28 printing the difference

Step 29 closing the scope of the main method

Output

 In this blog, we have learned how to create a c program to find  out the difference between the largest  and smallest elements of an array
