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 Triangle Pattern Programs 4: Star, Number, Alphabet & Binary Patterns with Output

Pattern Name

Left-Aligned Right-Angled Triangle Star Pattern 

Other acceptable names:

  • Increasing Star Triangle Pattern

  • Left-Aligned Triangle Pattern

  • Right-Angled Star Triangle

  • Half Pyramid Pattern using Stars

This is one of the most classic patterns for beginners in C programming









🔷 Left-Aligned Continuous Number Triangle Pattern

#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 j = 1; j <= i; j++)
        {
            printf("%d ", k++);
        }

        printf("\n");
    }

    return 0;
}










🔷 Triangle Binary Number Pattern

#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 j = 1; j <= i; j++)
        {
            printf("%d ", j % 2);
        }

        printf("\n");
    }

    return 0;
}
