Write a function called AddStringsstr1(Str1, Str2) that joins two null terminate

Question

Write a function called AddStringsstr1(Str1, Str2) that joins two null terminated ('C') strings and returns the address of the concatenated string. The caller has two null terminated strings ('C' strings) which are held in individual dynamically allocated memory blocks. The function accepts the addresses of these memory blocks as input parameters. The function is required to create a new memory block that is large enough to hold the concatenated string and returns the address of the new memory block holding the concatenated string.

Explanation / Answer

char* AddString(const char *s1, const char *s2)
{
    char *con_str= malloc(strlen(s1)+strlen(s2)+1);
    strcpy(con_str, s1);
    strcat(con_str, s2);
    return con_str;
}
