Thread: Text processing. Deleting words not starting with vowels

I am reading content from a file to be read into a char array in C. How could I delete words which are uppercase // or which start with a non-vowel? I really cant understand how to save the last c ==> how to check if you have space before vowel. Could you help me?

Code:

int main ()
{
FILE* read_me = fopen("x.txt","r");
if(!read_me)
printf ("NERA");
FILE* write_me = fopen("y.txt","w");
char c;
while((c=fgetc(read_me))!= EOF && c != EOF)
if(trink(c)==0)
{
fputc(c, write_me);
}
{
XXX
}
fclose (read_me);
fclose (write_me);
}

int trink (char w)
{
switch(w){
case'a':
case'A':
case'e':
case'E':
case'i':
case'I':
case'o':
case'O':
case'u':
case'U':
return1;
default:
return0;
}
}

You can make use of isupper(): isupper - C++ Reference

If you want to discard whole words that start with something you don't like, you need to keep discarding until you hit the next space or newline (not sure what your file looks like), but it'll essentially be like this:

while not EOF:

read character

if character is uppercase or is a vowel:

keep reading characters until newline or space (while loop)

else:

keep reading characters until newline or space (while loop)

copy character to output file
