i'm having real hard time with my code, and my due date is today. i'm given an error "main.c: In function ‘main’: main.c:186:7: error: expected declaration or statement at end of input }". I've been trying for hours to play with the brackets and fix it but with no luck. i'm hoping you could help me fix it, as you are far more experienced than me.
it's basically a simple program that takes input from stdin(might be from keyboard or from a file using redirection) and applies the following:
1)puts a new line between sentences. 2)doesn't print numbers. 3)if inside a bracket, then letters must be capitalized(bold). 4)put's an uppercase on a first character of a sentence. 5)if not in a bracket nor in a beginning of a sentence, then it should make it a lowercase.
notes: a)there's no limit on the length of the input, and each sentence can be written on several lines(the input). b)if a dot (.) is inside a brackets, it doesn't make it a new sentence(no need to write a newline). c)if two dots are given, then it's an empty sentence and should be written like the example.
basically, i just ask you to help me fix my code so it will run, as i've already done all of that(thought of i missed something and you can help me improve it - i will be very glad!)
example:
if given input:
i love to play hockey.. I NEED TO PLAY HOCKEY.. "hockey is life 3333".
the desired output will be:
I love to play hockey.
. I need to play hockey.
.
"HOCKEY IS LIFE"

i don't know how to fix it and i've spent hours on it. would be very grateful if you could help.
i've tried to be very elaborative and to abide the rules
You can try this to see if it produces the desired results.
Characters that are not letters, space, newline or dot are rejected at the top of the while and all letters are set to lower case.
Then the choice is to print one upper case letter at the start of the sentence or all upper case inside double quotes.
There are no breaks as oneUpper needs to fall through to allUpper. allUpper needs to fall through to default.
getchar returns an int so int a instead of char a
#include <stdio.h>
#include <ctype.h>
#define oneUpper 1
#define allUpper 2
int main (int argc, const char *argv[])
{
int status = oneUpper;
int a;
while ( EOF != (a = getchar ()))
{
//discard non letter except space, newline and .
if ( !isalpha ( a) && a != ' ' && a != '\"' && a != '.') {
continue;
}
//set all to lower and let oneUpper or allUpper do the rest.
a = tolower ( a);
switch (status)
{
case oneUpper:
if ( a == ' ' || a == '\n') {
putchar ( a);//print leading space and continue
continue;
}
case allUpper:
a = toupper ( a);
default:
putchar ( a);
if ( a == '\"') {
if ( status == allUpper) {
status = 0;//turn all upper off
}
else {
status = allUpper;//turn all upper on
}
}
if ( status == oneUpper) {
status = 0;//after printing one upper turn it off
}
if ( a == '.') {
if ( status != allUpper) {
putchar ( '\n');
status = oneUpper;//after a . turn one upper on
}
}
}
}
return 0;
}
