to remove all blank spaces in a string?

Question

c programming

Answer 1

check out Planet Source Code. http://www.pscode.com - you can search for "string manipulation" and restrict your result set to just C results.

Answer 2

You construct another string with the blank spaces removed...

I haven't done C in a while but it could be something like this...(my syntax is probably off depending on the version of C compiler you are using)
int n = strlen(oldString);
int c = 0;
char newString[n+1];
for(int x = 0; x < n; x++)
{

if (oldString[x]!=' ')
{
newString[c] = oldString[x];
c++;
}

}
newString[c] = '\0';


Something like the above anyway, I'm treating both strings as simple char arrays, and the new string has some wasted space at the end... this could be fixed by recopying it over again possibly using another str function.

Answer 3

use trim() in java this removes the blank places

Answer 4

Here's a simple function for you to use.

#include

// parameters:
// c: pointer to the string
// what it does:
// removes all whitespace in c,
// assumes c points at a null terminated string
void remove_whitespace(char *c)
{
. . . . char *write = c;
. . . . char *read = c;
. . . . for(; *read != '\0'; read++)
. . . . {
. . . . . . . . if(!isspace(*read))
. . . . . . . . {
. . . . . . . . . . . . *write++ = *read;
. . . . . . . . }
. . . . }
. . . . *write = '\0';
}
