Answer Posted / neo

didn't find the posts good enough, was looking for a very
structured code, professional:

<CODE>
{
int i, j, iLen;
char *sTmpStr;

iLen = (int) strlen(sStr);
sTmpStr = (char *)malloc(sizeof(char) * iLen);

for(i = 0;i < iLen; i++)
sTmpStr[i] = sStr[i];

for(i = 0, j = iLen - 1; i < iLen/2; i++, j--)
sStr[i] = sTmpStr[j];
free(sTmpStr);
return;
}


int main()
{
char sStr1[] = {"This is an awful string"};
char sStr2[] = {"This is a K...O...O...L string"};

printf("String 1: %s\n", sStr1);
StrRevNoTempVar(sStr1);
printf("String 1 Rev: %s\n", sStr1);

printf("String 2: %s\n", sStr2);
StrRevNoTempVar(sStr2);
printf("String 2 Rev: %s\n", sStr2);

return 0;
}
</CODE>
