else if后面不需要加分号，分号是语句结束的标志。

程序代码：

#include <stdio.h>

int main( void )
{
    int score;
    scanf( "%d", &score );

    if( score < 60 )
        puts( "E" );
    else if( score < 70 )
        puts( "D" );
    else if( score < 80 )
        puts( "C" );
    else if( score < 90 )
        puts( "B" );
    else
        puts( "A" );
}
