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)
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)
举一反三
- 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')
- 判断字符型变量c1是否为小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’)
- 判断CHAR型变量C1是否为大写字母的表达式是( )。 A: 'A'<=C1<='Z' B: C1>='A'&C1<='Z' C: 'A'<=C1&&C1>='Z' D: 'A'<=C1 AND C1>='Z'
