如何将输出存储到文件中 [英] How do I store the output to a file

问题描述

如何将以下程序的输出写入文件：



**程序基本上要求用户输入矩阵的值然后显示他们。**



该计划是：



#include< stdio.h>

main（）

{

int a [10] [10];

int i，j，n;

printf（输入n< 10 \ n的值）;

scanf（％d，& n）;

for（i = 0; i< n; i ++）

{

=for（j =0; j< n; j ++）

scanf（％d，& a [i] [j]）;

=}

=for（i = 0; i< n; i ++）

printf（％d，a [i] [j]）;

=printf（\ n ）;

=



=

i =know =how = to =write ==code =但=i =dont =can =store =contents =of =program =a =文件。

=

can =someone =kindly =tell =me =put =in = F ile？what =are =命令

any = help =will =be =有用



< b =>我尝试了什么：



程序给我输出但我不明白如何将输出存储到文件中。



有什么方法我将其存储在一个文件中。

How to write the output of the following program to a file:

**The program basically asks the user to input the values of a matrix and then displays them.**

The program is :

#include<stdio.h>
main()
{
int a[10][10];
int i,j,n;
printf("Enter the value of n<10\n");
scanf("%d",&n);
for(i=0;i<n;i++)
{
="" for(j="0;j<n;j++)
" scanf("%d,&a[i][j]);
="" }
="" for(i="0;i<n;i++)
" printf("%d,a[i][j]);
="" printf("\n");
=""

=""
i="" know="" how="" to="" write="" the="" code="" but="" i="" dont="" can="" store="" contents="" of="" program="" a="" file.
=""
can="" someone="" kindly="" tell="" me="" put="" in="" file?what="" are="" commands

="" needed

any="" help="" will="" be="" useful

<b="">What I have tried:

The program gives me the output but I dont understand how can I store the output to a file.

Is there any way I store it in a file.

推荐答案

使用 C库函数fprintf （） [ ^ ] - 有样本底部的代码。

Use C library function fprintf()[^] - there is sample code at the bottom.

最简单的方法是将可执行文件的标准输出重定向到一个文件（例如，参见：如何将命令提示输出重定向到文件[简单] [ ^ ]）。

The simplest way is to redirect the standard output of the executable to a file (see, for instance this: How to Redirect Command Prompt Output to a File [Easy][^]).
