I'm writing a basic piece of code to perform a successive approximation algorithm, however, when it runs the approximation loop, it seems unable to distinguish between a positive and a negative number in that it runs both if statements. The code is shown below, and if someone could point out where im going wrong, it would be really helpful.
#include <iostream.h>
int main(void)
{
float num1, num2, num3, num4, num5, num6, est, calcest, calcnum, calcdif, adj;
est = 5.0;
cout << "Please input first number: ";
cin >> num1;
cout <<num1;
cout << "\nPlease input second number: ";
cin >> num2;
cout << "\nPlease input third number: ";
cin >> num3;
cout << "\nPlease input fourth number: ";
cin >> num4;
cout << "\nPlease input fifth number: " ;
cin >> num5;
cout << "\nPlease input sixth number: ";
cin >> num6;
adj = est / 2;
cout << adj;
calcest = est * est * est * est * est * est;
cout << "\n" <<calcest;
calcnum = (num1 * num2 * num3 * num4 * num5 * num6);
cout << "\n" << calcnum;
calcdif = calcnum - calcest;
cout << "\n" << calcdif;
while ((calcdif >(-100)) || (calcdif >100));
{
if (calcdif < (-100));
{
est = est - adj;
adj = adj / 2;
}
else if (calcdif > 100);
{
est = est + adj;
adj = adj / 2;
}
calcest = est * est * est * est * est * est;
calcdif = calcnum - calcest;
}
cout << "\nThe geometric mean is" << est;
return 0;
