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 Decimal Conversion in C

#include<stdio.h>

int main()
{
    int num;

    printf("Enter any octal number:\n");
    scanf("%o",&num);

    printf("The Decimal value is:%d\n",num);

    return 0;
}

📘 Explanation:

This C program converts an octal number into its decimal equivalent using a format specifier.

The %o format specifier is used in scanf() to read an octal number.
The compiler automatically converts the octal input into decimal.
The result is printed using %d format specifier.
No manual conversion logic is required.

This is the simplest and most efficient way to convert octal to decimal in C.

🧾 Sample Output:

Enter any octal number:
17
The Decimal value is:15
