fortran中data
时间: 2024-01-02 07:04:42 浏览: 41
在Fortran中,`data`是一种设置初始值的语句。它可以用来初始化变量或数组的值。例如:
```
real :: x, y(3)
data x /1.0/
data y /2.0, 3.0, 4.0/
```
这里设置了变量`x`的初始值为1.0,并设置了数组`y`的初始值为2.0、3.0和4.0。
在Fortran 90及以上版本中,也可以使用`data`语句来为数组的某些部分设置初始值。例如:
```
real :: a(4, 4)
data a(1, 1:3) /1.0, 2.0, 3.0/
```
这里设置了数组`a`第一行的前三个元素的初始值为1.0、2.0和3.0。

fortran中data的用法
在 Fortran 中,data 语句通常用于初始化变量或数组的初始值。语法格式如下:
data 变量名 / 值1,值2,... /
其中,变量名是要初始化的变量或数组名称,值1,值2 等是用逗号分隔的初始值。如果是一个数组,可以为每个元素指定一个初始值。例如:
DATA a / 1, 2, 3, 4, 5 /
DATA b(2,2) / 1, 2, 3, 4 /
这将分别为数组 a 和 b 的元素设置初始值。

Data and Fortran are two distinct concepts in computer science.
Data refers to the raw information that is input into a computer system, such as numbers, text, images, or audio. This data can be processed by software applications to perform various tasks, such as data analysis, machine learning, or decision-making.
Fortran, on the other hand, is a high-level programming language that was originally developed for scientific and engineering applications. It is particularly well-suited for numerical computations, and is widely used in fields such as physics, chemistry, and engineering. Fortran has evolved over the years, and the latest version, Fortran 2018, includes many modern features such as object-oriented programming and support for parallel computing.
In summary, data and Fortran are two distinct aspects of computer science, with data referring to the raw information that is input into a system, and Fortran referring to a programming language that is commonly used for scientific and engineering applications.
