C Program to Calculate Simple Interest

C Program to Calculate Simple Interest

·                     Write a C program to read principal amount, rate of interest and time and calculate simple interest.

·                     Wap in C to find simple interest.

Required Knowledge

·                     C printf and scanf functions

·                     C Arithmetic Operators

We will first read Principle amount, rate of interest and time using scanf function. We will use below mentioned formulae to calculate Simple Interest (SI).

·                     Simple Interest = (Principle x Rate x Time) / 100

/*

 * C program to calculate simple interest

 */ 

 

#include <stdio.h> 

 

int main() { 

    float principle, rate, time, simpleInterest;   

 

    /*

     * Take Principle, Rate of interest and

     * Time as input from user.

     */ 

    printf("Enter Principle Amount\n"); 

    scanf("%f", &principle); 

    printf("Enter Rate of Interest\n"); 

    scanf("%f", &rate); 

    printf("Enter Time of Loan\n"); 

    scanf("%f", &time); 

 

    /*

     * Simple Interest = (Principle X Rate X Time)/100;

     */ 

    simpleInterest = (principle * rate * time)/100;  

 

    printf("Simple Interest = %.2f", simpleInterest); 

 

    return 0; 

}

Output

Enter Principle Amount

10000

Enter Rate of Interest

5

Enter Time of Loan

2

Simple Interest = 1000.00
