// I will only post the 2 functions I've used and the main()
one.

int StringLength(const char * s){
int l = 0;
while (*s++) l++;
return l;
}

char *StrCat(const char * str1, const char *str2){

int len1 = StringLength(str1);
int len2 = StringLength(str2);
int totLen = len1 + len2 + 1;

char * str12 = (char *)malloc((totLen)*sizeof(char));
memset(str12, '\0', totLen);

for (int i = 0; i < len1; i++)
*(str12 + i) = *(str1 + i);
for (int i = 0; i < len2; i++)
*(str12 + i + len1) = *(str2 + i);

return str12;
}


int main(int argc, char *argv[]){
char * S1= "ABCDE";
char * S2= "FGHIJ";

char *S12 = StrCat(S1, S2);
cout << "S12= "<< S12 << endl; // ABCDEFGH

return 0;
}
