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 Convert Hexadecimal to Octal

C Program to Convert Hexadecimal to Octal

✅ C Program to Convert Hexadecimal to Octal

#include <stdio.h>
int main() {
    int num;
    printf("Enter a hexadecimal number: ");
    scanf("%x", &num);   // read hex input

    printf("Octal: %o\n", num);   // print in octal
    return 0;
}

📘 Explanation:

This program converts a hexadecimal number into its octal form.

  • scanf("%x", &num) → reads a number in hexadecimal format and stores it as an integer.
  • printf("%o", num) → prints the same number in octal format.
  • No manual conversion is needed — C automatically handles it using format specifiers.

🧾 Sample Output:

Enter a hexadecimal number: 1A
Octal: 32

Enter a hexadecimal number: FF
Octal: 377
