this code is not working. there is some amendments required in this code.there should be strcpy(&x[nxtchar],&x[pos]); there is no need of while loop.

try this ... void stripLeadingSpaces( char str[] ) { int i, j=0; while (str[j]==' ') ++j; for (i=0; str[j]!=0; ++i, ++j) str=str[j]; str=0; }

For some strange reason the [ i ] was NOT there above ... it should be ... str[ i ] = str[ j ]; str[ i ] = 0; }
