判断字符型变量c1为小写字母的正确表达式为（）。
A: ‘a’<=c1<=‘z’
B: c1>=a&& c1<=z
C: c1>=‘a’|| c1<=‘z’
D: c1>=‘a’&& c1<=‘z’
A: ‘a’<=c1<=‘z’
B: c1>=a&& c1<=z
C: c1>=‘a’|| c1<=‘z’
D: c1>=‘a’&& c1<=‘z’
举一反三
- 判断字符型变量c1为小写字母的正确表达式为（）。 A: ‘a’<=c1<=‘z’ B: c1>=a&& c1<=z C: c1>=‘a’|| c1<=‘z’ D: c1>=‘a’&& c1<=‘z’
- 判断char型变量c1是否为大写字母的正确表达式是_____。 A: 'A'<=c1<='Z' B: (c1>='A')&(c1<='Z') C: (c1>='A')&&(c1<='Z') D: ('A'<=c1) AND ('Z'>=c1) E: ('A'<=c1)&&('Z'>=c1)
- 判断char型变量c1是否为大写字母的表达式为（ ）。 A: ’A’<=c1<=’Z’ B: (c1>=’A’) & (c1<=’Z’) C: （’A’<=c1）AND (‘Z’>=c1) D: c1>=’A’ && c1<=’Z’
- 判断char型变量c1是否为大写字母的正确表达式是（ ）。 A: 'A'<=c1<='Z' B: (c1>='A')&(c1<='Z') C: (c1>='A')&&(c1<='Z') D: ('A'<=c1)AND('Z'>=c1)
- 判断char型变量c1是否为大写字母的正确表达式为( )。 A: 'A'<=c1<='Z' B: (c1>=A. &&(c1<='z') C: ('A'>=c1)||('Z'<=c1) D: (c1>='A')&&(c1<='Z')
