Question #2: The following program reads integer numbers from a file named numbers.txt. For each number, the program computes the reverse in order to check whether the number is a palindrome number or not. It then reports the results into a file named Report.txt (A palindrome is any number whose reverse is also same, e.g., 1221, 23432, 7, 8 are palindromes, but 23489 is not). Suppose the file numbers.txt contains the following numbers: 373 11 2552 5 3561 numbers.txt Study the program carefully and answer the below questions; Hint: you might run the program before starting answering the questions! e) Show the output of the program. Assume that the file numbers.txt contains the data shown above f) As the program contains nested while loop, determine how many times the following statements will be executed: Assume that the file numbers.txt contains the data shown above 1) infile = fopen( "numbers.txt" , "" ); ....... time(s) 2) printf("%d is read from the file\n" , number); - time(s) 3) digit = temp % 10; time(s) ..... 4) printf("%d is a palindrome number! \n\n", number); time(s) g) How many times does the program check the condition of the outer while loop, i.e., status != EOF ?
