I wrote that program but spawnvp dows not call the exe files hello1,hello2!!!

#include <stdio.h>
#include <conio.h>
#include <process.h>

//Tv Rental system menu version 1
  int user_selection();
  void display_menu();
  void call_program(int option,char *argv[]);
int main(int ,char *argv[])
{
 int option;
 do
 {
  display_menu();
  option=user_selection();
  if (option!=7) //Exit
   call_program(option,argv);
 }
 while (option!=7);
 return 0;
  }


 void display_menu()
 {
  clrscr();
  printf("1 hello1");
  printf("\n2 hello2");
  printf("\n3 exit");
 }

 int user_selection()
 {
  int opt;
  printf("\n Enter required option(1-3)   :   ");
  scanf("%1d",&opt);
  return (opt);
 }

 void call_program(int opt,char *argv[])
 {
 void delay();
 switch(opt)
  {
 case 1:
  spawnvp(0,"hello1.exe",argv);
  delay();
  break;
 case 2:
  spawnvp(0,"hello2.exe",argv);
  delay();
  break;
 default:
  printf("\n incoreect input");
  delay();
  exit(0);
  }
 }
 void delay()
 {
  int i;
  for (i=0;i<20000;i++);
 }
