So berechnen Sie einfache und Zinseszinsen

Eskere Guru

Mathematik ist ein integraler Bestandteil der Programmierung. Wenn Sie einfache Probleme in diesem Bereich nicht lösen können, werden Sie viel mehr kämpfen als nötig.

Glücklicherweise ist es nicht allzu schwierig, dies zu lernen. In diesem Artikel erfahren Sie, wie Sie mit Python, C++ und JavaScript einfache Zinsen und Zinseszinsen berechnen.

Wie berechnet man einfache Zinsen?

Der einfache Zins ist eine Methode zur Berechnung des Zinsbetrags, der auf einen Hauptbetrag zu einem bestimmten Zinssatz und für einen bestimmten Zeitraum erhoben wird. Sie können den einfachen Zins berechnen, indem Sie die folgende Formel verwenden:

 Simple Interest = (P x R x T)/100
 Where,
 P = Principle Amount
 R = Rate
 T = Time

Die Problemstellung

Sie erhalten den Hauptbetrag , den Zinssatz und die Zeit . Sie müssen die einfachen Zinsen für die angegebenen Werte berechnen und drucken. Beispiel : Let Prinzip = 1000, Rate = 7 und timePeriod = 2. Simple Interest = (Prinzip * Rate * timePeriod) / 100 = (1000 * 7 * 2) / 100 = 140. Somit ist die Ausgabe 140.

Das C++-Programm zur Berechnung einfacher Zinsen

Unten ist das C++-Programm zur Berechnung von einfachen Zinsen:

 // C++ program to calculate simple interest
 // for given principle amount, time, and rate of interest.
 #include <bits/stdc++.h>
 using namespace std;
 // Function to calculate simple interest
 float calculateSimpleInterest(float principle, float rate, float timePeriod)
 {
 return (principle * rate * timePeriod) / 100;
 }

 int main()
 {
 float principle1 = 1000;
 float rate1 = 7;
 float timePeriod1 = 2;
 cout << "Test case: 1" << endl;
 cout << "Principle amount: " << principle1 << endl;
 cout << "Rate of interest: " << rate1 << endl;
 cout << "Time period: " << timePeriod1 << endl;
 cout << "Simple Interest: " << calculateSimpleInterest(principle1, rate1, timePeriod1) << endl;
 float principle2 = 5000;
 float rate2 = 5;
 float timePeriod2 = 1;
 cout << "Test case: 2" << endl;
 cout << "Principle amount: " << principle2 << endl;
 cout << "Rate of interest: " << rate2 << endl;
 cout << "Time period: " << timePeriod2 << endl;
 cout << "Simple Interest: " << calculateSimpleInterest(principle2, rate2, timePeriod2) << endl;
 float principle3 = 5800;
 float rate3 = 4;
 float timePeriod3 = 6;
 cout << "Test case: 3" << endl;
 cout << "Principle amount: " << principle3 << endl;
 cout << "Rate of interest: " << rate3 << endl;
 cout << "Time period: " << timePeriod3 << endl;
 cout << "Simple Interest: " << calculateSimpleInterest(principle3, rate3, timePeriod3) << endl;
 return 0;
 }

Ausgabe:

So berechnen Sie den Zinseszins

Der Zinseszins ist die Aufstockung der Zinsen auf den Kapitalbetrag. Mit anderen Worten: Zinsen über Zinsen. Sie können den Zinseszins berechnen, indem Sie die folgende Formel verwenden:

 Amount= P(1 + R/100)T
 Compound Interest = Amount – P
 Where,
 P = Principle Amount
 R = Rate
 T = Time

Die Problemstellung

Sie erhalten den Hauptbetrag , den Zinssatz und die Zeit . Sie müssen den Zinseszins für die angegebenen Werte berechnen und drucken. Beispiel : Let Prinzip = 1000, Rate = 7 und timePeriod = 2. Betrag = P(1 + R/100)T = 1144,9 Zinseszins = Betrag – Prinzip Betrag = 1144,9 – 1000 = 144,9 Somit ist die Ausgabe 144,9.

 float calculateCompoundInterest(float principle, float rate, float timePeriod)
 {
 double amount = principle * (pow((1 + rate / 100), timePeriod));
 return amount - principle;
 }

Kostenlos programmieren lernen: Beginnen Sie mit einfachen Zinsen und Zinseszinsen

Heutzutage nimmt die Bedeutung der Codierung exponentiell zu. Und damit einhergehend steigt auch die Nachfrage nach kompetenten Programmierern exponentiell. Es gibt ein Missverständnis unter den Leuten, dass sie das Programmieren nur lernen können, wenn sie eine hohe Gebühr bezahlen. Das stimmt aber nicht. Sie können von Plattformen wie freeCodeCamp, Khan Academy, YouTube usw. lernen, absolut kostenlos zu programmieren. Selbst wenn Sie kein großes Budget haben, müssen Sie sich keine Sorgen machen, etwas zu verpassen.
