A: 'I AM'
B: 'A STUDENT'
C: 'I AM A STUDENT'
D: 'IAMASTUDENT'
举一反三
- 已知s1="I "am a student.",s2='I \'am a student',则print(s1,s2)的输出结果为( ) A: I 'am a student. I 'am a student B: I "am a student. I 'am a student C: I "am a student. I \'am a student D: 程序报错
- (8)设串S1="I AM",S2="A SDUDENT",则ConcatStr(S1,S2)=
- 设s=’I AM A STUDENT’ , t=’GOOD’ , q=’WORKER’则Concat(Substring(s,6,2),Concat(t,Replace(s,’STUDENT’,q)))=( )
- 设串S1='ABCDEFG'，S2='PQRST' ,则ConcatStr(SubStr(S1,2,LenStr(S2)),SubStr(S1,LenStr(S2),2))的结果串为（ ）。
- 【单选题】如果输出语句:printf(“I am “student" you is teacher "). 显示内容? A. I am “student" you is teacher B. I am student you is teacher C. I am student you is teacher D. I am “student" you is teacher

下面语句的输出结果( )。<?php$str1="I am student ";$str2="Lily";$str3=str_replace("student",$str2,$str1)echo $str3;?> A: I am student B: I am Lily C: Lily am student D: I am student Lily

设串S1='ABCDEFG'，S2='PQRST' ,则ConcatStr(SubStr(S1,2,LenStr(S2)),SubStr(S1,LenStr(S2),2))的结果串为( )。 A: 'BCDEF' B: 'BCDEFG' C: 'BCPQRST' D: 'BCDEFEF'

下列程序的运行结果是（）。class student{function _construct(){echo "I am a student .<br>";}function teacher(){echo "I am a teacher";}}$per=new student(); A: I am a studentI am a teacher B: I am a student C: I am a teacher D: 无任何输出

设串S1=“ABCDEFG”,S2=“PQRST”,则ConcatStr(SubStr(S1,2,LenStr(S2)), A: bStr(S1,LenStr(S2),2))的结果串为()。 B: BCDEF C: BCDEFG D: BCPQRST E: BCDEFEF
