Hi, The modified program is not completely pasted in the answer. It is missing modified code for sleep() with sighandler, itimerval, sigaction. Can you please help give complete programs' to check the below. Can you please help provide modified code for the below for (int i = 0; i < char_int.number; i++) // This loop is used to display the decoded form of the pairing of character and integer // by printing the character so many times until it reaches the value of the integer // It will start from 0 and continues until i is less than integer { printf("%c", char_int.letter); // This print function is used to print the character // retrieved from the file } printf(" "); // Each record is printed on a new line } else { // The parity is odd, so the data is corrupted printf("Error: Odd parity "); } sleep(1); // This uses a sleep system call for the specified number of seconds until interrupted // Reading 1 character integer pair every second here 1 corresponds to every second } fclose(file1); // Closing the file after successfully reading the data return 0; }
