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 for Referencing and Dereferencing (Pointers)

✅ C Program for Referencing and Dereferencing (Pointers)

#include<stdio.h>
int main()
{
    int x = 10;
    int *ptr = &x;   // Referencing = storing the address of variable 'x' into pointer 'ptr'.

    printf("%d", *ptr);  // Dereferencing = fetching the value stored at that address (here 10).
}
  

๐Ÿ“˜ Explanation:

Pointers in C are used to store the address of variables. - Referencing (&): The & operator is used to get the address of a variable. - Dereferencing (*): The * operator is used to fetch the value stored at that address.

In this program:

  • int *ptr = &x; → stores the address of x into pointer ptr.
  • *ptr → retrieves the value stored at that address (10).

๐Ÿงพ Sample Output:

10
