NettetC[解析] 选项A)中,字符型变量a,b中间缺少逗号;如果对几个变量赋以同一个初值,不能在定义变量时进行,应写成:float a=10.0,b=10.0;所以选项B)不正确;选项D)中,执行b=&a相当于将地址转换成了浮点型,编译时将提示出错信息“无效的类型转换”,所以选 … Nettet24. jan. 2014 · In Java, the following is allowed: char c = 'A' + 1; Here, c will hold the value 'B'. Above, first the expression is evaluated. So 'A' gets converted to 65, the whole expression evaluates to 66, and then 66 is converted to 'B' since we are storing the value in a char. The following, however, gives a compile-time error: char c = 'A'; c = c + 1; joseph andrews md psychiatrist
c语言char与int区别,例如让int a=65或char a=65,他们在输出时 …
Nettetchar a = 65; Verwenden Sie jetzt im Programm das Formatierungszeichen %c, wird der Wert 65 anhand der ASCII-Code-Tabelle kodiert. Wird hierbei das Formatierungszeichen %d verwendet, würde dieser Wert nicht kodiert und in seiner tatsächlichen Form ausgegeben, wobei »tatsächliche Form« natürlich rein optisch gemeint ist. When you write any letter in between single apostrophes, you refer them as a char. This means they can be referred to as a numeric value. In your case, 'A' refers to the ascii value of 65, while 'B' refers to 66 and 'C' refers to 67. The compiler then implicitly converts the int value into a char value where required, like in your case. joseph andriacchi retired
