Thread: Removing whitespace

Ok, well you are trying...try this.

Code:

char *Trim(char *source)
{

int len = strlen(source);

if(len == 0){char *error = malloc(1); return error = 0;}

char *target = malloc(len);

int a = 0;

while(a < len)
if(!isspace(source[a++]))
break;

int x = len;

while(x > 0)
if(!isspace(source[x--]))
break;

int i = 0;

for(i = a; i <= x; i++)
*target++= source[i];

target[strlen(target)-1] = 0;

return target;
}

But remember that because the memory for the target string is allocated within the function, (has to be), do not allocate for it in the main program:

char string[] = " Programming is fun !!! ";

char *trim = malloc(strlen(string));
trim = Trim(string);
// !...Memory Leak...! //

char *trim = Trim(string);
// !...Correct...! //
