Need help,im beginner

Hello guys
I want to reverse some text and delete the spaces if the spaces are more than one

i mean this :
hello world ---> hello world
4 spaces ---> 1 space

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;
}

this code was fore reverse

Code:

int main()
{
   char text[100], blank[100];
   int c = 0, d = 0;
  
   printf("Enter some text\n");
   gets(text);
  
   while (text[c] != '\0')
   {
      if (!(text[c] == ' ' && text[c+1] == ' ')) {
        blank[d] = text[c];
        d++;
      }
      c++;
   }
  
   blank[d] = '\0';
  
   printf("Text after removing blanks\n%s\n", blank);
 system("PAUSE");
   return 0;
}

and thi code was fore deleting spaces

but i want to reverse and delete spaces at the same time,can anyone give me a solution ?
i want these two codes in one
thanks a lot

 

Nice job with trying it out.

beware when using gets; that function doesn't check that input will fit within your array and will gladly overflow if allowed to.

Since you're using a temp array as well, add another argument to your function

Code:

void myfunction(char *src, char *des) {

   /* reverse a string and remove extra spaces */

   int i = strlen(src) - 1, j = 0, spc = 0;

   while(i >= 0) {
      if(spc == 0 && src[i] == ' ') // is src[i] a space ??
         spc = 1; // it's a space, so set flag         
      else {
         while(src[i] == ' ') // loop while src[i] is extra spaces
            --i; 
          spc = 0; // reset space flag
      }

      des[j] = src[i]; 
      --i;
      ++j;
   }

   des[j] = '\0'; // add string termination char
}

to test with, from main

Code:

char source[] = "string       with        extra      spaces",
     dest[50] = { 0 };

myfunction(source, dest);
puts(source);
puts(dest);

make sure the destination string is big enough and is initialized to get rid of any junk chars.

hope that helps.
