Greatest Elements in an array in C++ Programming

The program finds the greatest element in an array entered by the user.

The program starts by declaring an integer array a of size 100 and variables n (for the size of the array), i (for loop iteration), and t (to store the greatest element).
The user is then prompted to enter the size of the array, which is stored in the variable n. The program then uses a for loop to prompt the user to enter values for each element in the array, which are stored in the array a.
Next, the program sets the variable t to the first element of the array a (i.e., t=a[0]). It then uses another for loop to iterate over the remaining elements in the array a and compare each element with the current value of t. If an element is greater than t, then t is updated to that element.
Finally, the program prints the value of t, which is the greatest element in the array.

Overall, the program allows the user to enter any number of elements in an array and then finds and prints the greatest element in the array.

Source Code

#include<iostream>
using namespace std;
//Program to find Greatest element in an array.
int main()
{
    int a[100],n,i,t;
    cout<<"\nEnter The Limit : ";
    cin>>n;//3
    for(i=0; i<n; i++)
    {
        cout<<"\nEnter The Value  : ";
        cin>>a[i];
    }//10,20,30
    t=a[0];//10
    for(i=1; i<n; i++)
    {
        if(t<a[i])//10<20  20<30
        {
            t=a[i];//20  30
        }
    }
    cout<<"\nThe Greatest No is : "<<t;
    return 0;
}

Output

Enter The Limit : 5

Enter The Value  : 23

Enter The Value  : 12

Enter The Value  : 34

Enter The Value  : 2

Enter The Value  : 34

The Greatest No is : 34
