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.
float principal_amt, rate, simple_interest;
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);
$ 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
