C++ little question

Hi,

I am doing a C++ self-study and I got stuck with this problem.
I want to have a code that asks the suer to enter two numbers and then it lists the numbers between these two numbers. It has also to print a message if these two numbers are equal.
Here is what I wrote:

Code:

#include <iostream>

int main()
{
  int i, j;
  std::cout << "Enter two numbers:" << std::endl;
  std::cin >> i >> j;
  std::cout << "You etered: " << i << " and " << j << "!" << std::endl;
  
  if (i=j)
    std::cout << "They are equal" << std::endl;
  else {
    if (i<j) {
      std::cout << i << std::endl;
      ++i;
    }
    else if (i>j) {
      std::cout << j << std::endl;
      j++;
    }
  }  
  return 0;  
  
}

I have also tried many alterations using while and for statements. My question is: Why it does stuck at the first if statement, and then quits?

Thanks,

faizlo

tau_get_event_vals

TAU_GET_EVENT_VALS(3)					      TAU Instrumentation API					     TAU_GET_EVENT_VALS(3)

NAME

       TAU_GET_EVENT_VALS - Gets user event data for given user events.

SYNOPSIS

       C/C++:

       TAU_GET_EVENT_VALS(const char **inUserEvents, int numUserEvents, int **numEvents, double **max, double **min, double **mean,
			  double **sumSqe);

DESCRIPTION

       Retrieves user defined event data for the specified user defined events. The list of events are specified by the first parameter
       (eventList) and the user specifies the number of events in the second parameter (numUserEvents). TAU returns the number of times the event
       was invoked in the numUserEvents. The max, min, mean values are returned in the following parameters. TAU computes the sum of squares of
       the given event and returns this value in the next argument (sumSqe).

EXAMPLE

       C/C++ :

	 const char **eventList;
	 int numEvents;

	 TAU_GET_EVENT_NAMES(eventList, numEvents);

	 cout << "numEvents: " << numEvents << endl;

	 if (numEvents > 0) {
	   int *numSamples;
	   double *max;
	   double *min;
	   double *mean;
	   double *sumSqr;

	   TAU_GET_EVENT_VALS(eventList, numEvents, numSamples,
	     max, min, mean, sumSqr);
	   for (int i=0; i<numEvents; i++) {
	     cout << "-------------------
";
	     cout << "User Event:	 " << eventList[i] << endl;
	     cout << "Number of Samples: " << numSamples[i] << endl;
	     cout << "Maximum Value:	 " << max[i] << endl;
	     cout << "Minimum Value:	 " << min[i] << endl;
	     cout << "Mean Value:	 " << mean[i] << endl;
	     cout << "Sum Squared:	 " << sumSqr[i] << endl;
	   }
	 }
       }
