#include<unistd.h>
#include<string.h>
char * StrCat(const char*, const char*);
int StrLen(const char *);
int main(int argc, char *argv[])
{
char *FinalString = NULL;
if(argc < 3)
{
printf("Usage: <%s> <String -1> <String -2>\n",argv
[0]);
return -1;
}
FinalString = StrCat(argv[1],argv[2]);
printf("The Final String is::: \n[%s]\n",FinalString);
if(FinalString != NULL)
{
free(FinalString);
FinalString = NULL;
}
return 0;
}
char *StrCat(const char *_input1, const char *_input2)
{
char *_output;
int _strLen, _cntr1, _cntr2;
_strLen = StrLen(_input1)+StrLen(_input2)+1;
_output = (char *)malloc(_strLen);

_cntr2 = 0;
while(*(_input1 + _cntr1) != NULL)
{
