C++ Exercises: Find power of any number using for loop

Sample Solution:-

C++ Code :

#include <iostream> // Including the input/output stream library

using namespace std; // Using the standard namespace

int main() // Main function where the execution of the program starts
{
    int bs, ex, num = 1, i; // Declare integer variables bs, ex, num, and i

    // Display messages asking for input
    cout << "\n\n Find power of any number using for loop:\n";
    cout << "---------------------------------------------\n";
    cout << " Input the base: ";
    cin >> bs; // Read the base value from the user
    cout << " Input the exponent: ";
    cin >> ex; // Read the exponent value from the user

    // Loop to calculate the power of the base number
    for (i = 1; i <= ex; i++) 
    {
        num = num * bs; // Multiply num by base 'ex' times to get the power
    }

    // Display the result of base raised to the exponent
    cout << bs << " ^ " << ex << " = " << num << endl;
}

Sample Output:

 Find power of any number using for loop:                              
---------------------------------------------                          
 Input the base: 2                                                     
 Input the exponent: 5                                                 
2 ^ 5 = 32
