**Record the common problems you encounter in file operations**
The case of garbled output
When using C language, we generally use fopenfunctions to open files, as follows
#include<stdio.h>
int main()
{
FILE *fp;
char a[10];
fp=fopen("temp.txt","r");
fscanf(fp,"%s",a);
printf("%s\n",a);
return 0;
}
If the output is all garbled characters
, open the corresponding temp.txt text file, select the file in the upper left corner to save it as, change the encoding from UTF-8 to ANSI at the bottom and save it, and then output the text normally (be careful not to memory space exceeded).

fopenSome operation applications of functions
fopen("***.txt","w");
When using fopenthe function to open a file, if you want to continue writing data on the original basis, use awill wclear the original data in the document first, and a is to add data at the end of the document, and the pointer points to the end of the document.
It can also be used r+, r+and w+both are read-write modes, the difference is that w+the file will be cleared first.
