函数InStr(LCase(Mid("VISUAL Basic程序设计"，4，8))，"s")的值是______。
A: Ual BASIC
B: 6
C: 7
D: UAL Basic
A: Ual BASIC
B: 6
C: 7
D: UAL Basic
举一反三
- 设a="Visual Basic"，下面使b="Basic"的语句是（ ）。 A: b=Right$(a,5,5) B: b=Mid$(a,8,5) C: b=InStr(a,8) D: b=Left$(a,8,5)
- 执行以下程序段后，变量c$的值为（）。 a$＝"Visual Basic Programming" b$＝"Quick" c$＝b$ & UCase(Mid$(a$，7，6)) & Right$(d$,12) A: Visual BASIC Programming B: Quick Basic Programming C: QUICK Basic Programming D: Quick BASIC Programming
- 执行以下程序段后,变量c$的值为( )。 a$="Visual Basic Programming" b$="Quick" c$=:b$ & UCase (Mid$ (a$,7,,6)) & Right$ (a$,12) A: Quick BASIC Programming B: Quick Basic Programming C: Visual BASIC Programming D: QUICK Basic Programming
- 执行以下程序段后,变量c$的值为: A: ="Visual Basic Programming" B: ="Quick" C: =b$ & UCase(Mid$(a$，7，6))&Right$(a$,1 2) D: Visual Basic Programming E: Quick Basic Programming F: QUICK Basic Programming G: Quick BASIC Programming
- 计算表达式Right(Mid("Visual Basic",4,5),1) &Left(Mid("程序设计",1,8),2)的值
