Code problem

[dot_rain]

/* simply exercise */
#include <stdio.h>

/* function main begins program execution */
int main()
{
   int grade   /* declare */
   
   printf( "Enter your grade: " );
   scanf( "%d", &grade );

   if ( grade >= 90 )
      printf( "A\n" );
   else if ( grade >= 80 )
      printf( "B\n" );
   else if ( grade >= 70 )
      printf( "C\n" );
   else
      printf( "D\n");

return 0;   /* end program successfully */

} /* end function main */

no matter whatever number I enter , it just show A

>scanf( "%d", grade );
Should be

scanf( "%d", &grade );

scanf requires an address so that it can modify the variable you pass it instead of a copy. And you're missing a semicolon in the declaration:

int grade   /* declare */

But I assume that was a typo when you posted, otherwise it wouldn't compile.
