Indexing files to write to?
I'm writing a program and I want to put a written file inside a for loop. For each run through the loop, I want to write to a different file. How do I do this? Here's the code:
Code:
for(f=0;f<files;f++) {
srand(f);
output= fopen("sequence.in","w"); //now open/create file for writing
for(t=0;t<number;t++) { //bases are generated with the given frequencies
rand=rnum();
if(rand<freqa) {
base='A';
}
if(rand>=freqa && rand< (freqa + freqt)) {
base='T';
}
if(rand>=(freqa + freqt) && rand< (freqa + freqt + freqg)) {
base='G';
}
if(rand>= (1 - freqc) && rand<1.00) {
base='C';
}
fprintf(output, "%c",base);
}
fprintf(output, "%c",'Q'); //add 'Q' to end of file (quit command in program that will read the file)
fclose(output);
}
I tried putting a '%d' inside the fopen command where I specify the name of the file, but that obviously didn't work. Ideally, I'd like it to write files with the names sequence0.in, sequence1.in, etc. up to whatever value I feed it for the variable 'files.' Is there any way to do what I'm trying to accomplish?
