1. / / this is a code segment for file ing and capitalization of lowercase. Make complaints about the fastest answer to the problem. So many, dizzy, writing may not be good, there is anything you don't understand, you can continue to ask

int main (void) {
int ch// Define a character variable to store a character of the file as an intermediate variable,
file * source, * destination// Define two file pointers, but do not point to any file for the time being
char source_ name[41],destination_ name[41]; // Define two character arrays to store the source file name and destination file name
printf & quot; input the source file' s name:"); // The output prompt information requires the input of the source file name

2. This guy's code quality is so poor, and the variable name defined has certain randomness, so there's no reason to
as for multiplying by 0.75, I think it's wrong
don't use garbage code to learn, this kind of code is very poor
