C program to Calculate Simple Interest

 In this post I will tell you how to write  C program to calculate Simple Interest .  So, without any further delay let's get started.

Code:

#include<stdio.h>

int main(){

  int principal;

  float rate,time,simpleInterest;

  printf("Enter principal amount \n");

  scanf("%d",&principal);

  printf("Enter rate of interest\n");

  scanf("%f",&rate);

  printf("Enter time(means year)\n");

  scanf("%f",&time);

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

  printf("Simple Interset=%f\n",simpleInterest);

    return  0;

}

Logic:                                                                                                  We know that in S.I.=P*R*T/100 .Here P means principal amount ,R means rate at which it is increasing. And last T is time for which money is given .And multiplication of P*R*T divides by 100 . Gives us Simple Interest .Now I show you code  screen shot for your  comfort . I paste screen shot Here int principal; is called variable declaration in c language and here int is datatype means simply we said to compiler that you take value in principal in form of integer numbers .Float is also datatype and I will discuss this particular topic in detail in another post. And scanf here take value in variables using format specifier like %d for int ,%f  for float etc. And you will eager to see output of this program.

Output:

And I hope you will try by yourself on your pc and also try for other numbers . And last most important tip for you guys that always &(means at this address ) while taking input through user.

I hope this might helpful to you.
