File Processing

if you'd like to open a file and read from that file or you want to write a file based on what you've inputted on your program, this is the way.

i'll explain how to read and write file.

read file, it is easier to make a function just to read file, so i'll just make a function.

int readFile() {
//there are 3 process here, first is open the file, the reading process, and last but not least close the file.
FILE * fp = fopen("/*this id the file name, the one you'd like to read*/", "r"); // r means read

while(!feof(fp)) { //feof means end of file, so as ling as there are something to read, they'll scan it
fscanf(fp, "/*this is the file format, e.g. %s#%d", /*this is where you want to put the file to*/
}

fclose(fp);

}

for the write file you'll just do the same thing but jut change the "r" to "w" and fscanf to fprintf syntax.

see, not that complicated.
good luck.
