fp=fopen("exp.txt","w");
while( (ch=getchar()) !=EOF)

putc(ch,fp);

fclose(fp);
return 0;
}I am using gcc compiler in linux mint
This code is not working only exp.txt is created which is empty.
exp.txt is created which is empty.
Since "ch" has no value you don't write anything in the file
Since "ch" has no value you don't write anything in the file
using getchar() we are taking input from the keyboard from the user
till it reaches the eof
but problem is how to take eof from the keyboard
What value do you get when you "take eof from the keyboard"?
#include <stdio.h> #include <stdlib.h> int main() { FILE *fp; char ch; fp=fopen("exp.txt","w"); while( (ch=getchar()) !=EOF) { putc(ch,fp); } fclose(fp); return 0; }I am using gcc compiler in linux mint

your program is correct , just press CTRL+D at the end of your input.
however need to check whether file open is success.
fp = fopen("exp.txt","w");
if ( fp ) {
do file operations
}
