I have some input like this:
" aaaaa bbb \n cccccc\n ddddd \neeee "
And I need to sanitize it like this:
"aaaaa bbb cccccc ddddd neeee"
Basically:
Is there any easy way to do this or I'll have to process the string, char by char and copy the appropriate chars to a different variable?
Assuming you cannot modify string in place,
void splcpy(char *s, char *m){ //s is the unmodified string
int word = -1; //keeps track what was stored in last loop
while(*s){ //until it ends
if(!isspace(*s)){
if(word==0) *m++ = ' '; //if last char was space, add space
*m++ = *s++;
word = 1;
}
else{
if(word == 1) word = 0; //if last char was !space
while(isspace(*s++)); //consume all space until end
}
}
*m = '\0'; //end the string nicely
}
char *input = " aaaaa bbb \n cccccc\n ddddd \neeee ";
char *modified = malloc(sizeof(char) * strlen(input));
splcpy(input, modified);
