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 Print Continuous Number Triangle Pattern
📄 Source Code:
#include <stdio.h>
int main()
{
int num, k = 0;
printf("Enter the number:\n");
scanf("%d", &num);
for(int i = 1; i <= num; i++)
{
for(int k = num; k >= i; k--)
{
printf(" ");
}
for(int j = 1; j <= i; j++)
{
printf("%d ", k++);
}
printf("\n");
}
return 0;
}
⚠️ Note: In this program, the variable k is declared twice (once globally and once inside the loop). The outer k is used for printing numbers, while the inner k is used for spacing.
💻 Expected Output (Input: 5):
Enter the number:
5
0
1 2
3 4 5
6 7 8 9
10 11 12 13 14
📝 Explanation
This program prints a continuous number triangle pattern using nested loops.
The first inner loop prints spaces for alignment. The variable k
starts from 0 and increments after every number is printed, resulting in a
sequence of continuous numbers throughout the triangle.
⏱ Time Complexity
O(n²) because nested loops are used to print spaces and numbers.

📝 Explanation
This program prints a repeated number triangle pattern using nested loops.
The first inner loop prints spaces for alignment, while the second inner loop
prints the current row number repeatedly. As the value of i
decreases, the triangle grows wider and displays the same number multiple times
in each row.
⏱ Time Complexity
O(n²) because nested loops are used to print spaces and numbers.

📝 Explanation
This program prints an increasing number triangle pattern using nested loops.
The first inner loop prints spaces for alignment, while the second inner loop
prints numbers starting from the current row value up to the entered number.
As the rows increase, more numbers are displayed, forming a triangle pattern.
⏱ Time Complexity
O(n²) because nested loops are used to print spaces and numbers.

📝 Explanation
This program prints a repeated alphabet triangle pattern using nested loops.
The first inner loop prints spaces to align the triangle, while the second
inner loop prints the same alphabet multiple times in each row. The expression
i + 64 converts the row number into its corresponding uppercase
alphabet using ASCII values (1=A, 2=B, 3=C, and so on).
