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++) { ...

Octal to Hexadecimal Conversion in C

Octal to Hexadecimal Conversion in C

#include<stdio.h>

int main()
{
    int num;
    printf("Enter any octal number:\n");
    scanf("%o", &num);
    printf("Hexadecimal value is: %X\n", num);

    return 0;
}

📘 Explanation:

This C program converts an octal number into its hexadecimal equivalent using format specifiers.

  • The %o format specifier in scanf() reads an octal number.
  • The compiler internally converts the octal value into decimal.
  • The %X format specifier in printf() prints the value in hexadecimal (uppercase).
  • No manual conversion logic is required.

This is a simple and efficient way to convert octal to hexadecimal in C.

🧾 Sample Output:

Enter any octal number:
17
Hexadecimal value is: F
