如写成以下形式就错了: main( f float score; scanf(%of, &score) if(score<60)printf( Fail n); else if(score>=60) printf("Pass") else if(score>=80) printf("Goodn") else printf("very Good n")如写成以下形式就错了： main( ) { float score; scanf(″%f″, &score); if (score<60) printf(″Fail\n″); else if(score>=60) printf(″Pass\n″); else if(score>=80) printf(″Good\n″); else printf(″Very Good\n″); }
