C-Program to calculate simple and compound interest

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

#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

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

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
