PROGRAMMING FOR PROBLEM SOLVING LAB : Program 4

 4.  Write the program for the simple, compound interest.

#include<stdio.h> 
#include<math.h> 
void main()
{
int n;
float p,q,r,SI=0,CI=0; 
clrscr();
printf("\n Enter the value of Principal p = "); 
scanf("%f",&p);
printf("\n Enter the value of Rate r = "); 
scanf("%f",&r);
printf("\n Enter the value of Period in year n = "); 
scanf("%d",&n);
SI = ((p*r*n)/100);
printf("\n Simple Interest SI=%f \n",SI); 
q = 1+(r/100);
CI=p*pow(q,n)-p;
printf("\n Compound Interest CI=%f \n",CI); 
getch();
}

OUTPUT:

Enter the value of Principal p = 3500
Enter the value of Rate r = 4
Enter the value of Period in year n = 2
Simple Interest SI=280.000000 
 Compound Interest CI=285.599731
