  • C Program to Calculate Simple Interest using Function

Algorithm to Calculate Simple Interest

Follow the below given algorithm to write a program to calculate simple interest; as follows:

  • Get input principle amount and store in some variable.
  • Get input time and store in some variable..
  • Get input rate and store in some variable..
  • To calculate simple interest using formula SI = (principle * time * rate) / 100.
  • Finally, print the result of simple interest.

C Program to Calculate Simple Interest using Formula

/**
 * C program to calculate simple interest
 */
#include <stdio.h>
int main()
{
    float principle, time, rate, SI;
    /* Input principle, rate and time */
    printf("Enter principle (amount): ");
    scanf("%f", &principle);
    printf("Enter time: ");
    scanf("%f", &time);
    printf("Enter rate: ");
    scanf("%f", &rate);
    /* Calculate simple interest */
    SI = (principle * time * rate) / 100;
    /* Print the resultant value of SI */
    printf("Simple Interest = %f", SI);
    return 0;
}

The result of the above c program; as follows:

Enter principle (amount): 10000
Enter time: 1.5
Enter rate: 5
Simple Interest = 750.000000

C Program to Calculate Simple Interest using Function

/**
 * C program to calculate simple interest
 */
#include <stdio.h>
// function for finding simple interest
float SimpleInt(float p, float r, float t) 
{
    float si;   
    si = (p * r * t)/100; // formula
    return si; // returning yhe value of si
}
int main()
{
    float principle, time, rate, SI;
    /* Input principle, rate and time */
    printf("Enter principle (amount): ");
    scanf("%f", &principle);
    printf("Enter time: ");
    scanf("%f", &time);
    printf("Enter rate: ");
    scanf("%f", &rate);
    /* Call function with paramters to Calculate simple interest */
     SI = SimpleInt(principle, rate, time); 
    /* Print the resultant value of SI */
    printf("Simple Interest = %f", SI);
    return 0;
}

The result of the above c program; as follows:

Enter principle (amount): 20000
Enter time: 2
Enter rate: 5
Simple Interest = 2000.000000
