Learn this program step-by-step with algorithm, source code, output and detailed explanation.
Design a class to overload a function series( ) as follows:
(a) void series (int x, int n) – To display the sum of the series given below:
x1 + x2 + x3 + .......... xn terms
(b) void series (int p) – To display the following series:
0, 7, 26, 63 .......... p terms
(c) void series () – To display the sum of the series given below:
1/2 + 1/3 + 1/4 + .......... 1/10
public class RansariOverloadSeries {
// Overloaded method to calculate the sum of powers of x up to n
void series(int x, int n) {
long sum = 0;
for (int i = 1; i <= n; i++) {
sum += Math.pow(x, i);
}
System.out.println("Sum = " + sum);
}
// Overloaded method to print the first p terms of the sequence i^3 - 1
void series(int p) {
for (int i = 1; i <= p; i++) {
int term = (int) (Math.pow(i, 3) - 1);
System.out.print(term + " ");
}
System.out.println();
}
// Overloaded method to calculate the sum of a harmonic series from 1/2 to 1/10
void series() {
double sum = 0.0;
for (int i = 2; i <= 10; i++) {
sum += 1.0 / i;
}
System.out.println("Sum = " + sum);
}
}
// Main class to test the RansariOverloadSeries methods
class Main {
public static void main(String[] args) {
// Create an object of RansariOverloadSeries
RansariOverloadSeries series = new RansariOverloadSeries();
// Test the method: series(int x, int n)
System.out.println("Testing series(int x, int n):");
series.series(2, 5); // Example: x = 2, n = 5
// Test the method: series(int p)
System.out.println("Testing series(int p):");
series.series(5); // Example: p = 5
// Test the method: series()
System.out.println("Testing series():");
series.series();
}
}
Testing series(int x, int n):
Sum = 62
Testing series(int p):
0 7 26 63 124
Testing series():
Sum = 1.9277777777777778
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
