Need help,im beginner

Hello guys,im beginner
Im trying to reverse some texts and delete spaces.if spaces are more than one
i mean this :
hello world ---> hello world
4 spaces ---> 1 space

i tryed to reverse the texts successfully like this

Code:

---


void reversed(char str[]);
int main(int argc, char *argv[])
{
    char str[100];
    printf("enter text : ");
    gets(str);
  reversed(str);
    return 0;
}
void reversed(char str[])
{
    int i;
    for (i = strlen(str) - 1; i>=0; i--)
    printf("%c",str[i]);
    printf("\n");
  system("PAUSE");   
  return 0;
}

---

but i want to delete the spaces at the same time and dont know how
Thanks.

Maybe you could check if the character is a space before you print it?

And don't use gets! FAQ > Why gets() is bad / Buffer Overflows - Cprogramming.com

  while (text[c] != '\0')
  {
      if (!(text[c] == ' ' && text[c+1] == ' ')) {

  blank[d] = '\0';
 
  printf("Text after removing blanks\n%s\n", blank);

}

First, follow rag_to_riches advise about gets usage.
Second, nobody here will give you a complete solution.
Third, normally, a function should do one thing and do it well. So reversing a string AND removing the spaces at the same time may not be the wisest method. Also, you don't have to be bang on the first time. Divide your problem into smaller increments. Then once you have a working solution, see how you could improve upon.
