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++) { ...

📘 Explanation
This program prints an inverted binary triangle pattern using nested loops.
The first inner loop prints leading spaces to shift the pattern toward the right.
The second inner loop prints either 0 or 1 based on the current row number using the expression i%2.
Odd-numbered rows print 1s, while even-numbered rows print 0s.
The number of values decreases in each row, creating an inverted triangular pattern.
🧠 Algorithm
Read the number from the user.
Run the outer loop from 1 to num.
Print leading spaces using the first inner loop.
Print the value of i%2 repeatedly in each row.
Move to the next line after completing a row.
Repeat until the pattern is completed.

This program prints an inverted right-aligned repeated alphabet triangle pattern.
The first inner loop prints leading spaces, causing the pattern to shift towards the right on each row.
The second inner loop prints the same alphabet repeatedly in each row.
The expression i + 64 converts the current row number into its corresponding uppercase alphabet using ASCII values.
Since the outer loop decreases from num to 1, both the alphabet and the number of characters decrease in each row.

📘 Explanation
This program displays a right-aligned, inverted character triangle pattern by pairing nested loop logic with character type formatting via ASCII offsets.
The outer loop controls rows using a decrementing index i starting from the user's input down to 1.
The first inner loop k tracks spacing; as i drops, the expression forces an increasing block of double spaces, padding the structure dynamically to the right.
The second inner loop j prints alphabets up to the current row width i. By applying the format specifier %c to the mathematical integer logic j + 64, it maps loop increments directly to uppercase ASCII boundaries where 65 yields 'A', 66 yields 'B', and so on.

📘 Explanation
This program combines right-alignment spacing with row-based binary logic to print a mirrored triangle pattern.
The outer loop i runs from 1 up to the user-input number, controlling the row processing.
The first inner loop k handles right-alignment by generating double spaces, which decrease as i increases.
The second inner loop j manages the actual value output. Instead of counting up, it prints the evaluation of i % 2.
Because the display relies on the row index i, all elements within a single row match: odd rows print entirely as 1s and even rows print entirely as 0s.

📘 Explanation
This program creates a right-aligned triangle pattern using numbers. It shifts the pattern to the right by using two separate inner loops inside a single outer loop.
The outer loop i controls the total number of rows from 1 up to the entered number.
The first inner loop k handles the formatting by printing leading double spaces, which decreases in count as we move down the rows.
The second inner loop j runs from 1 up to the current row number i, printing incrementing numbers separated by spaces to form the final structure.
