It's seem cannot print out! Help! Noob Here.

[Joshua Eduarte]

Hello. I'm an engineering student and i have a problem with my program that I encode. It seem's that it can not print out the results. This program is all about finding the roots of a specific function using Regula Falsi Method.

This is my program:

#include<iostream>
#include <stdlib.h>
#include<cmath>
using namespace std;
int main()
{
double a,b=0,c,d=0,e=0,f=0,g,i,t=0.000010,p=3.1416;
cout<<"Choose from the two equation to find its roots:\n 1:x^3-7x^2+6x+5 \t 2: 3x+sinx+e^x\n";
cin>>g;
if(g==1)
{
a=1;
c=2;
for(i=1;e>=t;i++)
{
d=pow(a,3)-(7*pow(a,2))+(6*a)+5;
f=pow(c,3)-(7*pow(c,2))+(6*c)+5;
b=(c*d)-(a*f)/(d-f);
e=pow(b,3)-(7*pow(b,2))+(6*b)+5;
cout<<a<<b<<c<<d<<e<<f;
if(d*e>0)
{c=b;}
else if (d*e<0)
a=b;
}
}
else if (g==2)
{
a=0;
c=1;
for(i=1;e>=t;i++)
{
d=(3*a)+sin(a*p/180)-exp(a);
f=(3*c)+sin(c*p/180)-exp(c);
b=(c*d)-(a*f)/(d-f);
e=(3*b)+sin(b*p/180)-exp(b);
cout<<a<<b<<c<<d<<e<<f;
if(d*e>0)
{c=b;}
else if (d*e<0)
a=b;
}
}

system("pause");
return (0);
}


Please help me.. Thank you.

for(i=1;e>=t;i++)

This for loop will repeat as long as e is greater than or equal to t. What is the value of e and the value of t the first time this loop is reached? So how many times will it loop?

Does the program require that you put the cout inside the for loop? If not simply putting a cout statement after the for loop finishes should do the trick.

EDIT: not sure why you're using a for loop, the loop will run until a condition is met, which is why a while loop will suit the program better. Using a while loop the program ran fine.
