Question1:

The following program contains five errors. Identify the errors and fix them.  (10 marks)

 


  1.   int main(void) {
  2. char source[10];
  3. char *dest;
  4. size_ti;

  1. strcpy(source, "0123456789");
  2. dest = malloc(strlen(source));
  3. for (i = 1; i <= 11; i++) {
  4. dest[i] = source [i];
  5. }
  6. dest[i] = '\0';
  7. printf("dest = %s", dest);

  1. return 0;
  2. }

 

Answer: 

 

In line 5 source size is 10 bytes long but we tries to copy 11 bytes , this error can be fixed by increasing the size of source variable to 11.

 

In line 6, strlen will not count the null byte this will allocate only 10 bytes and it can be fixed by using sizeof in place of strlen.

 

In line 7, i starts from 1 which is wrong as it should starts from 0.

 

In line 9, i terminates with value 11 but it should only loop through 10. It can be fixed by changing the terminating condition.

 

In line 10, i value will be 11 which is wrong as it can have maximum value of 10. It can be fixed by fixing the line 9.
