计算表达式Right(Mid("Visual Basic",4,5),1) &Left(Mid("程序设计",1,8),2)的值
举一反三
- 设S="中华人民共和国",表达式Left(S,1)+Right(S,1)+Mid(S,3,2)的值为()
- 设a="Visual Basic"，下面语句中可使b="Basic"的是( )。 A: b=Left(a,8) B: b=Mid(a,8,5) C: b=Right(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$,7,,6)) & Right$ (a$,12) A: Quick BASIC Programming B: Quick Basic Programming C: Visual BASIC Programming D: QUICK Basic Programming
- 设a="Visual Basic",函数Left(a,3)的值为________,Mid(a,8,5)值为________
- 执行以下程序段后,变量c$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
