如何进行强制类型转换？

[gyk120]

#include <windows.h>
#include <stdio.h>
#include <string.h>
#include "stdafx.h"


int main(int argc, char* argv[])
{
char password=0;
printf("Enter the password");
scanf("%d",password);
if(password=="abc")
WinExec("cmd.exe", SW_SHOWNORMAL);
else
printf("access denied");

return 0;
}
编译报错：
error C2446: '==' : no conversion from 'char *' to 'int'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast
error C2040: '==' : 'int' differs in levels of indirection from 'char [4]'
执行 cl.exe 时出错.
个人猜测是要进行强制类型转换，不过C当中强制类型转换机制是怎么做的？对VC还不是很熟悉，C也学得不好……Delphi倒是可以Sender as XXXX，C里面该如何去做？

int main( int argc, char* argv[] )
{
	char password[128]={0};
	printf( "Enter the password" );
	scanf( "%s", password );

	if ( 0 == strcmp( password , "abc") )
		WinExec( "cmd.exe", SW_SHOWNORMAL );
	else
		printf( "access denied" );
	return 0;
}

字符不能跟字符串比较

[delphiwcdj]

int main(int argc, char* argv[]) 
{ 
  char password[128]={0};//修改 
  printf("Enter the password"); 
  scanf("%s",password); //修改
  if(password=="abc") //两个字符串相比较
  WinExec("cmd.exe", SW_SHOWNORMAL); 
  else 
  printf("access denied"); 

return 0; 
}
