无符号整型变量表示为( )。
A: unsigned char
B: signed char
C: unsigned int
D: signed int
A: unsigned char
B: signed char
C: unsigned int
D: signed int
举一反三
- 正确定义无符号整型变量m的语句是( ) A: int m; B: unsigned int m; C: signed int m; D: unsigned signed m;
- 若-120<i<+100,则应该定义变量i的数据类型为()。 A: unsigned char i B: signed char i C: unsigned int i D: signed int i
- 想要定义一个无符号整型变量a,下列语句正确的是() A: int a; B: signed int a; C: unsigned int a; D: int unsigned a;
- 无符号整型表示为 A: signed B: unsigned
- 在进行C51程序设计时,如无特殊需要,通常选择____类型的变量。 A: float B: unsigned<br/>int C: unsigned<br/>char D: signed<br/>char
