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 Program to Print Prime Numbers Between Two Numbers

#include <stdio.h>
int main( )
{
    int start,end,count,i,j;
    printf("Enter the start and ending values of the prime number:\n");
    scanf("%d %d",&start,&end);
    
    for(i=start;i<end;i++)
    {
        count=0;
        for(j=1;j<=i;j++)
        {
            if(i%j==0)
            {
                count++;
            }
        }
        if(count==2)
        {
            printf("%d ",i);
        }
    }
}

📘 Explanation:

This program prints all prime numbers between two given numbers. A prime number is a number that has exactly two divisors: 1 and itself.

Take starting and ending range from the user.
For each number in the range, check how many divisors it has.
If the count of divisors is exactly 2, it is a prime number.
Print the number if it satisfies the prime condition.

🧾 Sample Output:

Enter the start and ending values of the prime number:
10 25
11 13 17 19 23
