How To Find The Smallest And Second Smallest Elements In A Given Array C program to find the 2nd smallest number in an array to make this program, we will use the following concept which is given below. if you do not know about these topics well, then you may not understand this program, so you should know about them in detail from the link given below. The below printf statement is to print the smallest number inside an array. in this c program example, it is 6. printf("\nsmallest element in an array = %d", smallest); the below printf statement used to print the index position of the largest number inside an array. in this example, it occurs at position 2.
C Program To Find Smallest Number In An Array An o(1) sollution might be to just guess: the smallest number in your array will often be 0. 0 crops up everywhere. given that you are only looking at unsigned numbers. but even then: 0 is good enough. also, looking through all elements for the smallest number is a real pain. why not just use 0? it could actually be the correct result!. Efficient solution can find the minimum two elements in one traversal. below is the complete algorithm. algorithm: 1. initialize both first and second smallest as int max. first = second = int max. 2. loop through all the elements. if the current element is smaller than first, then update first and second. Explanation: the maximum of the array is 5. and the minimum of the array is 1. input: arr [] = {5, 3, 7, 4, 2} output: maximum is: 7. minimum is: 2. approach 1 (greedy): the problem can be solved using the greedy approach: the solution is to compare each array element for minimum and maximum elements by considering a single item at a time. Step 1 → take an array a and define its values. step 2 → declare smallest as integer. step 3 → set smallest to 0. step 4 → loop for each value of a. step 5 → if a[n] < smallest, assign a[n] to smallest. step 6 → after loop finishes, display smallest as smallest element of array. stop.
Let Us C Solutions Chap8 I C Finding Smallest Number In Array Using Explanation: the maximum of the array is 5. and the minimum of the array is 1. input: arr [] = {5, 3, 7, 4, 2} output: maximum is: 7. minimum is: 2. approach 1 (greedy): the problem can be solved using the greedy approach: the solution is to compare each array element for minimum and maximum elements by considering a single item at a time. Step 1 → take an array a and define its values. step 2 → declare smallest as integer. step 3 → set smallest to 0. step 4 → loop for each value of a. step 5 → if a[n] < smallest, assign a[n] to smallest. step 6 → after loop finishes, display smallest as smallest element of array. stop. To find the smallest element in a given array in c programming, you must first ask the user to enter all of the array's elements. then, as shown in the program below, find smalls from all: #include<stdio.h> #include<conio.h> int main() {. int arr[10], small, i;. Step by step working of the above program code: let us assume that a user enters the number of elements as 5. then the user enters 5 elements as { 6 4 7 2 5 }. so it stores the elements in the array a []= { 6,4,7,2,5 }. now it assigns the value of a [0] to small (i.e. small=6 ). then it assigns the value of i=1 and the loop continues till the.
