source code is the programming code written by a programmer which tells the computer what to do. it's written in a computer language such as c++ or python and is stored in files on the computer. when the program is executed, it reads each line of code and carries out whatever ...
Java中,`+`运算符用于数值类型的变量时执行加法运算,结果为两者的算术和。因此,此处的输出应为5 + 2 = 7。 逐项分析选项: - **(a)5+2**:错误。若为字符串拼接(如`"5" + "2"`),结果可能是"52",但此处操作数是整数,需进行加法运算。
Physical output includes things like: a print out from a computer or a final sum from a database program. Code output is useful to developers. In complex code, different functions and procedures work on an array of variables and values. When one of these is passed from one function to ...
