This is an example of clearing the C language console

Suppose we have a 'new.txt' file with the following content-

0,hell!o
1,hello!
2,gfdtrhtrhrt
3,demo

Now, let's look at an example.

Example

#include<stdio.h>
#include<conio.h>
void main()　{
　　　FILE　*f;
　　　char s;
　　　clrscr();
　　　f=fopen("new.txt","r");
　　　while((s=fgetc(f))!=EOF)　{
　　　　　　printf("%c", s);
　　　}
　　　fclose(f);
　　　getch();
}

Output Result

0,hell!o
1,hello!
2,gfdtrhtrhrt
3,demo
