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是否为大写字母的正确表达式是 A: 'A'<=c1<='Z' B: (c1>=A)&& 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为( )。 A: ’A’<;=c1<;=’Z’ B: (c1>;=’A’) & (c1<;=’Z’) C: (’A’<;=c1)AND (‘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’)
