C++ : WAP to calculate simple interest using inline function.

#include<iostream>
#include<conio.h>

using namespace std;

float interest(float p,float t,float r)
{
return((p*t*r)/100);
}

int main()
{
float p,t,r;
cout<<"Principle = ";cin>>p;
cout<<"Time = ";cin>>t;
cout<<"Rate = ";cin>>r;
cout<<"Simple Interest = "<<interest(p,t,r);
getch();
return(0);

}
