Consider the statements in lines 4 and 5 are written in different lines. Due to saving spaces they are written in the same line.

1. void main( ) {

2 char *str1 = malloc(sizeof(char) * 16);

3 char *str2 = malloc(sizeof(char) * 16);

4 str1[0] = 'p'; str1[1] = 'a'; str1[2] = 's'; str1[3] = 's';

5 str1[4] = ','; str1[5] = '\0';

6 printf("%s ", str1);

7 Str2 = str1;

8 str2[0] = 'y';

9 str2[1] = 'e';

10 printf("%s ", str1);

11 printf("%s ", str2);

12 str2 = NULL;

13 printf("%s ", str1);

14 strcpy(str1, "pass the exam!");

15 printf("%s ", str1);

16 free(str1);

17 free(str2);

}

1. Draw the status of the memory after line 7. Show where Str1 and Str2 are pointing and draw rectangular array boxes as needed to show the dynamically allocated memory status.
2. There is a memory leak on line 7. Explain why?
3. What will be the output of the program?
