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’)
- 设char c1;则c1为小写英文字母字符的正确表达式为( )。 A: (c1>=a)&&(c1<=z) B: 'a'<=c1='z' C: (c1>='a')&&(c1<='z') D: ('a'<=c1) || ('z'>=c1)
- 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)
