Answer to question 1:
Error 1: The character array source on line 2 has a length of 10 bytes but the function strcpy() in
line 5 copies 11 characters including the null character. To fix this error the length of the source
character array should be changed to 11.
Error 2: In line 6 the definition of malloc function is written wrong.
The correct way to define that line would be: char *dest = (char *)malloc(strlen(source));
Error 3: In the for loop the index value of i, present in line 7, starts at 1, but the first position in
a C array is indexed at 0. The solution to this problem is to start the for loop with 0.
Error 4: In line 7 the for loop has an ending condition as i<=11 and for this the loop will iterate
extra one time even if the programmer does not want it to be. The solution to this would be to
change the value of iteration to i<11 or i<=10.
Error 5: On line 10 it is an out of bound write. The solution to this would be just to remove that
line from the code.
