I am making a program to compute simple interest. P*R/100

this is what i have done... Please tell me whats wrong

``````int main()
{
int p,n,count;
float r,si;

count=1;
while(count<=3)
{
printf("\n enter values of p,n,andr");
scanf("%d %d %f",&p, &n, &r);
si=(float)p * (float)n * r / 100;
printf("simple interest =rs. %f",si);
count=count+1;
}

return(0);
}``````

We're not in the guessing game here - so how about giving us a hand and telling us what you think is wrong.

For one, if your code snippet is meant to be a full posting of code, then you are missing the include directive for stdio.h. I'm not sure why you have the loop in place. Your code style needs a bit of work. Other than that the "dinky" little piece of code seems to work OK for me.

you need to enter the like this (p*n*r)/100 to get the simple intrest coz ur code reduces the rate of intrest since it is r/100 and not pnr/100

``````int main()	{
float principle, rate, n ,interest;
int count = 0;
while(++count <= 3)	{
printf("\nPlease enter the principle, rate and number: ");
scanf("%f %f %f", &principle, &rate, &n);
interest = (principle * rate * n) / 100;
printf("%f", interest);
}
}``````

Shouldn't all the variable except count be floats? Because you can have a principle of 100.54 and n could also be 10.5 etc. Also why are you looping through 3 times?
