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 find the largest element in an array using simple iteration

Find Largest Element in Array - C Program

🔍 Find Largest Element in an Array (C Program)

#include<stdio.h>
int main( )
{
    int num,a[100];
    printf("Enter the size of the array:\n");
    scanf("%d",&num);
    if(num<=0)
    {
        printf("Invalid array size");
        return 1;
    }
    printf("Enter %d elements into the array:\n", num);
    for(int i=0;i<num;i++)
    {
        scanf("%d",&a[i]);
    }
    int max=a[0];
    for(int i=0;i<num;i++)
    {
        if(a[i]>max)
        {
            max=a[i];
        }
    }
    printf("The largest element in array is %d\n",max);
}

📘 Explanation:

🔹 The program first reads the size and elements of the array.
🔹 It initializes `max` with the first element.
🔹 Then it iterates through all elements and updates `max` whenever a larger value is found.
🔹 Finally, it prints the largest element.

🧪 Sample Output:

Enter the size of the array:
5
Enter 5 elements into the array:
10 45 23 89 34
The largest element in array is 89
