int num2=2
if(num1<num2
{
cout << num1<<num2*2endl;
num1=num1+1;

Re: C++ help with a PROGRAM

You need a loop construct:

int i;

for (i = 0; i <= 100; i += 2) {
//print i
}

something like that outa work.

Re: It didnt work tortelli

I need help in creating a C++ program, to display all even numbers between 1 and 100, (such as 2, 4, 6, 8 etc). The program would go something like:

#include <iostream.h>

int main ( )
{
int num1=1;
int num2=2;

if (num1=0; num2<100; num2=1=2){
cout<<
}
return 0;
}

Re: C++ help with a PROGRAM

if you wanted to go beyond the call of duty you could do one of these:

C++ Syntax (Toggle Plain Text)
#include <iostream.h>
#include <stdlib.h>
void main()
{
 int MAX;
 cout<<"Enter a number to count by two to: ";
 cin>>MAX;
 for (int x = 0; x <= MAX; x++)
 {
  if (x % 2 == 0)
  {cout << x << endl;}
 }
 system("pause");
}
#include <iostream.h>
#include <stdlib.h>
void main()
{
 int MAX;
 cout<<"Enter a number to count by two to: ";
 cin>>MAX;
 for (int x = 0; x <= MAX; x++)
 {
  if (x % 2 == 0)
  {cout << x << endl;}
 }
 system("pause");
}
