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 Reverse a Number and Preserve Trailing Zeros

🔁 C Program to Reverse a Number and Preserve Trailing Zeros

#include<stdio.h>
int main( )
{
    int num,reverse=0,original,zero=0,remainder;
    printf("Enter the number:\n");
    scanf("%d",&num);
    original=num;
    while(original%10==0&&original!=0)
    {
        zero++;
        original=original/10;
    }
    while(num!=0)
    {
        remainder=num%10;
        reverse=reverse*10+remainder;
        num=num/10;
    }
    printf("Reversed Number is:%d",reverse);
    for(int i=0;i<zero;i++)
    {
        printf("0");
    }
    printf("\n");
}

📝 Explanation:

This program reverses a number while preserving its trailing zeros. For example, 54000 becomes 45 followed by three zeros → Reversed Number is: 45 000.

💡 Sample Output:

Enter the number:
54000
Reversed Number is:45 000
