2 - WAP that calculates the Simple Interest and Compound Interest. The Principal. ,Amount. Rate of Interest and Time are entered through the keyboard.

C-Program to calculate simple and compound interest

#include<stdio.h>

#include<math.h>

int main()

{

float p,q,r,SI,CI;

int n;

printf("Enter the value of Principal p = ");

scanf("%f",&p);

printf("Enter the value of Rate r = ");

scanf("%f",&r);

printf("Enter the value of Period in year n = ");

scanf("%d",&n);

SI = ((p*r*n)/100);

printf("Simple Interest SI=%f \n",SI);

q = 1+(r/100);

CI=p*pow(q,n)-p;

printf("Compound Interest CI=%f \n",CI);

return 0;

}

Sample Input
Enter the value of Principal p = 1000
Enter the value of Rate r = 12
Enter the value of Period in year n = 2
Sample Output
Simple Interest SI=240.000000
Compound Interest CI=254.400009

Input

#include<stdio.h>
void main()
{
	float p,r,t,i;
	clrscr();
	printf("Enter principal amount : ");
	scanf("%f",&p);
	printf("\nEnter Rate of Interest : ");
	scanf("%f",&r);
	printf("\nEnter time period : ");
	scanf("%f",&t);
	i=(p*r*t)/100;
	printf("\nInterest calculated is %f",i);
	getch();
}

Output

Enter principal amount : 5000
 
Enter Rate of Interest : 10.5
 
Enter time period : 7
 
Interest calculated is 3675.000000
