sorry,
updated code posted correctly.
Did I say I am new to this.

#include "LedControl.h"

LedControl lc=LedControl(12,11,10,1);
unsigned long delaytime=200;//  v*75
void setup() {
  /*
   The MAX72XX is in power-saving mode on startup,
   we have to do a wakeup call
   */
  lc.shutdown(0,false);
  /* Set the brightness to a medium values */
  lc.setIntensity(0,8);
  /* and clear the display */
  lc.clearDisplay(0);
  int v = 0;
}
void loop() 
  
// function to send digits to 7 seg led

{
  for(int v=0;v<99;v++)  {
  
  int ones;
  int tens;
  boolean zero; 
  
  if(v > 99) 
    return;
  ones=v%10;
  v=v/10;
  tens=v%10;
  v=v/10;
  
  lc.setDigit(0,1,(byte)tens,false);
  lc.setDigit(0,0,(byte)ones,false);
  delay(3000);
}
}
