read character from file

Hi,

Any ideas on how to read characters from a .txt and then display them on the screne?

Thanks

Try to do some research before you ask:
http://www.cprogramming.com/tutorial/cfileio.html

first of all i did my recearh BEFORE i asked.

This is my problem

Code:

---


do {
infile1=fopen("encrypted.txt", "r");
fscanf(infile1, "%s", &output);
//printf("lol");
printf("%c", output);
}
while(output != EOF); // check to make sure user has input

---

The problem is that it keeps on printing the first chacter over and over again on the screne.

Can anyone see the problem with the code?

BTW: Its my first semester taking C, hence my name.

Well you keep opening the file each time around the loop.

Code:

---

int ch;
infile1=fopen("encrypted.txt", "r");
while ( ( ch = fgetc(infile1) ) != EOF ) {
  putchar( ch );
}

---

Thanks for your help... since i am still studying C, i was trying to figure out how to do that for a few hours. You saved me a lot of time.

Now I have another problem.
I have to read charcter from a .txt file.

Then i must have some sort of loop that would check for certain characters and replace them with ones that have been predefined by the user using a pointer. (no writing to a file involved yet). Single chatactets only, ie it will not search for a KJ rather for K, then subsitute. Then J, then subsitute.

I figured out how to allow the user to specify the value of the pointers.

Now i have to write to modified characters to another text file.


One more thing, how many people here are computer engineer majors, and how many are computer science?
