Checks if parameter c is a white-space character.For the purpose of this function, standard white-space characters are:
' '
(0x20)

'\n'
(0x0a)
newline (LF)
'\v'
(0x0b)
vertical tab (VT)
'\f'
(0x0c)
feed (FF)
'\r'
(0x0d)
carriage return (CR)

while (str[i])
{
c=str[i];
if (isspace(c)) c='\n';
putchar (c);
i++;
}
return 0;
}
/*
This code prints out the C string character by character, replacing any white-space character by a newline character. Output:
