1. Write a function Equal to test whether two strings are equal. Equal should return 1 if the two string parms contain the same chars, and return 0 otherwise.
2. Write a function that has two parms: a string and a char. The function should return the subscript of the first occurrence of the char, or a -1 if the char is not in the string. For example, if the string is "yes i can" and the char is 'c', the function should return 6.
3. Write a function trimfront that removes all leading blanks from the string passed to it.
4. What does the following code print?

     char line[80] = "this is a test; IT IS ONLY A TEST";
     char first[21];
     char sec[21];
     char third[31];
     cout << "line is: " << line << endl;
     strncpy(first,line,4);
     first[4] = '\0';
     cout << "length of first: " << strlen(first) << endl;
     cout << "first is: " << first << endl;
     strcat(line,first);
     cout << "line is: " << line << endl;
     strncpy(sec,line,14);
     sec[14] = '\0';
     strcpy(third,sec);
     for (int i = 0 ; i < strlen(third) ; i++)
       third[i] = toupper(third[i]);
     cout << "third is: " << third << endl;
     cout << "sec is: " << sec << endl;
   

5. Write a function int concat(char str1[],char str2[],int maxlen) that uses strlen, strcat, and strncat. Your concat function should perform a complete concatenation of str2 onto the end of str1 only if the length of the concatenated string will not exceed maxlen-1 (the amount of room in str1). If the concatenated string will exceed maxlen-1 chars, concatenate only the first part of str2 so that the result will have length maxlen-1.
