C++ Program to Perform Linear Search on a Vector

  C++ Program to Perform Linear Search on a Vector Introduction In this C++ program, we will learn how to perform a Linear Search on a vector. The program first takes the size of the vector and its elements as input. Then it asks the user for the element to search. If the element is found, it displays the index where it is located. Otherwise, it displays a message indicating that the element is not found. C++ Program #include<bits/stdc++.h> using namespace std; int main() { int num, search, found = 0; cout << "Enter the size of the vector:" << endl; cin >> num; vector<int> v(num); cout << "Enter " << num << " elements in vector:" << endl; for(int i = 0; i < num; i++) { cin >> v[i]; } cout << "Enter element that you want to search:" << endl; cin >> search; for(int i = 0; i < num; i++) { ...

C program to find the smallest element in an array using bubble sort

Smallest Element in Array - C Program

🔹 Find Smallest Element in Array (C Program)

#include <stdio.h>

void smallest(int a[], int num)
{
    // Sort array in ascending order using Bubble Sort
    for (int i = 0; i < num - 1; i++)
    {
        for (int j = 0; j < num - i - 1; j++)
        {
            if (a[j] > a[j + 1])
            {
                int temp = a[j];
                a[j] = a[j + 1];
                a[j + 1] = temp;
            }
        }
    }

    // The smallest element will be at index 0
    printf("Smallest element in the array: %d\n", a[0]);
}

int main()
{
    int num;
    printf("Enter the size of the array:\n");
    scanf("%d", &num);

    if (num < 1)
    {
        printf("Invalid! Need at least 1 number to find the smallest element.\n");
        return 1;
    }

    int a[num];
    printf("Enter %d elements:\n", num);
    for (int i = 0; i < num; i++)
    {
        scanf("%d", &a[i]);
    }

    smallest(a, num);
    return 0;
}

📘 Explanation:

  • Takes input for size and elements of the array.
  • Uses Bubble Sort to sort the array in ascending order.
  • After sorting, the smallest element will be at index 0.
  • Handles invalid input if less than 1 element is entered.

🧪 Sample Output:

Enter the size of the array:
4
Enter 4 elements:
22 7 13 9
Smallest element in the array: 7
