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 Remove Duplicate Elements from an Array

🧹 C Program to Remove Duplicate Elements from an Array

#include<stdio.h>
int main( )
{
    int num;
    printf("Enter the size of the array:\n");
    scanf("%d",&num);
    if(num<=0)
    {
        printf("!invalid array size:\n");
        return 1;
    }
    int a[num];
    printf("Enter %d elements:\n",num);
    for(int i=0;i<num;i++)
    {
        scanf("%d",&a[i]);
    }
    for(int i=0;i<num;i++)
    {
        for(int j=i+1;j<num;)
        {
            if(a[i]==a[j])
            {
                for(int k=j;k<num-1;k++)
                {
                    a[k]=a[k+1];
                }
                num--;
            }
            else
            {
                j++;
            }
        }
    }
    printf("Ater Removing Duplicates from Array:\n");
    for(int i=0;i<num;i++)
    {
        printf("%d ",a[i]);
    }
}

📝 Explanation:

This program accepts an integer array from the user, removes all duplicate elements by shifting elements to the left, and prints the updated array without duplicates.

💡 Sample Output:

Enter the size of the array:
6
Enter 6 elements:
1 2 3 2 4 1
Ater Removing Duplicates from Array:
1 2 3 4
