This is a C Program to calculate the simple interest.

This C Program calculates the simple interest.

This C Program calculates the simple interest given the principal amount, rate of interest and time. The formula to calculate the simple interest is: simple_interest = (p * t * r) / 100 where p is principal amount, t is time & r is rate of interest.

Here is source code of the C program to calculate the simple interest. The C program is successfully compiled and run on a Linux system. The program output is also shown below.

/* * C program to find the simple interest, given principal, * rate of interest and time. */ #include <stdio.h> void main() { float principal_amt, rate, simple_interest; int time; printf("Enter the values of principal_amt, rate and time \n"); scanf("%f %f %d", &principal_amt, &rate, &time); simple_interest = (principal_amt * rate * time) / 100.0; printf("Amount = Rs. %5.2f\n", principal_amt); printf("Rate = Rs. %5.2f%\n", rate); printf("Time = %d years\n", time); printf("Simple interest = %5.2f\n", simple_interest); }

This C program, we are reading the value for principal_amt, rate and time using the ‘principal_amt’, ‘rate’ and ‘time’ variables respectively.

To find the simple interest, the following formula is used.

simple_interest = (principal_amt * time * rate) / 100

$ cc pgm3.c $ a.out Enter the values of principal_amt, rate and time 12 10 5 Amount = Rs. 12.00 Rate = Rs. 10.00% Time = 5 years Simple interest = 6.00
