Step by step
Solved in 2 steps
- Compile the program using $ gcc -o mycat filecopy.c mycat.c /* filecopy: copy file ifp to file ofp */ #include <stdio.h> void filecopy(FILE *ifp, FILE *ofp) { int c; while ((c = getc(ifp)) != EOF) putc(c,ofp); } #include <stdio.h> /* mycat: concatenate files */ void filecopy(FILE *, FILE *); int main(int argc, char *argv[]){ FILE *fp; if (argc == 1){ /* no args, copy standard input */ filecopy(stdin, stdout); }else{ while (--argc > 0){ if ((fp = fopen(*++argv, "r")) == NULL) { printf("cat: cannot open %s\n", *argv); return 1; } else { filecopy(fp, stdout); fclose(fp); } } } return 0; }FileAttributes.c 1. Create a new C source code file named FileAttributes.c preprocessor 2. Include the following C libraries a. stdio.h b. stdlib.h c. time.h d. string.h e. dirent.h f. sys/stat.h 3. Function prototype for function printAttributes() main() 4. Write the main function to do the following a. Return type int b. Empty parameter list c. Declare a variable of data type struct stat to store the attribute structure (i.e. statBuff) d. Declare a variable of data type int to store an error code (i.e. err) e. Declare a variable of data type struct dirent as a pointer (i.e. de) f. Declare a variable of data type DIR as a pointer set equal to function call opendir() passing explicit text “.” as an argument to indicate the current directory (i.e. dr) g. If the DIR variable is equal to NULL do the following i. Output to the…Directions: Typing make at the command line should create executable named bitflip. Only bitflip.c and Makefile are included in the input unless permission is given for any other files. Program should have consistent indentation. Code should be readable with good variable and function names. No use of "break or continue statements" except in a switch. Program must exit with a return code of 0 on success and an error code in other cases. The program used getopt to parse the command line. Whenever an error occurs on the command line the user is given the usage statement and an appropriate error message if needed. If the -o option is used the output will go to a file named as specified without changing the filename at all otherwise it will go to stdout. -e option works as specified using bitwise operations. -f option works as specified using bitwise operations. -a option works as specified using bitwise operations. -s option works as specified using bitwise operations. Program outputs…
- C++: Assume that there is a valid file named cards.txt in the current directory which contains an int. The following is a code snippet which needs to read the int from the file and print it out to the screen. What do you need to replace ????? with in order to do this? ifstream ifs; int x; ????? ifs >> x; cout << x << endl; A) ifs >> x; B) ifs.open("cards.txt"); C) ifs.input(x); D) cin >> x;C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found.C Programming What does the below do? Where is the output going? Where is the input coming from? #include <stdio.h> #define RECORD_LENGTH 60 void main(void) { FILE *fptr; char stock_price_shares[RECORD_LENGTH + 1]; if ((fptr = fopen("PORTFOLIO.DAT", "r")) == NULL) printf("\nCannot open the file: PORTFOLIO.DAT\n"); else { while ( fgets(stock_price_shares, RECORD_LENGTH + 1, fptr) != NULL ) fprintf(stdout, "\n%s", stock_price_shares); fclose(fptr); //close the file } }
- Chapter 4. PC #14. Line Numbers (page 265) Write a java program that asks the user for the name of a file. The program should display the contents of the file with each line preceded with a line number followed by a colon. The line numbering should start at 1. I should be easily type input1.txt and easily print out the output in Eclipse. Please enter the file name or type QUIT to exit:\nquitENTER Test Case 2 Please enter the file name or type QUIT to exit:\nbadfilename.txtENTERFile: badfilename.txt does not exist.\nPlease enter the file name again or type QUIT to exit:\nquitENTER Test Case 3 Please enter the file name or type QUIT to exit:\ninput1.txtENTER1: a\n2: b\n3: c\n4: d\n2. Message Decoder Create a MessageDecoder program that reads from a file (one character at a time), and writes all non-numeric characters to a file called DecodedMessage.txt, displaying a secret (and motivational) message. ***Hint: .read() will return an int, but this can be type cast as a char. int and char are interchangeable (via type-caşting). You could run a loop on a condition like charInFile != (char) -1 Don't forget that -1 is a special character that denotes the end of a file!Python 3 Given that a variable named pathName contains a string describing a directory path, write a single Python statement that will store the names of all files and subdirectories in that path in a List structure named contents. DO NOT traverse the path/directory. You are only interested in the immediate path and its contents. You may assume that any necessary import statements already exist.
- All I need is the main.cpp file Programming Specifications: Task: Two files have been provided (wordcounter.h and wordcount.cpp). You must open a text file, read in each word until end of file, add each word to the WordCount library and print the report. Your program must request a filename of a text file that contains words to count. You must check to see if it is a valid file and issue an error message if not and request a new file name until a valid one is entered. You must have at least one function that either passes in a parameter and at least one function that returns a value. You can have a single routine that does both. You must declare the class object properly, use AddWord() to add the word to the catalog and use PrintSummary() to produce the output. Design Considerations: The file will contain only words (no punctuation or special characters) less than or equal to 13 letters. There will be no limit to the number of words. You must open the file and read each…Modify this program so that it writes the values in two columns, like this: 32.00 54.00 67.50 29.00 35.00 80.00 115.00 44.50 100.00 65.00 Total: 622.00 Complete the following file: total.cpp 1 #include #include 3 #include #include 5 using namespace std; 4 7 int main() 8 { // Prompt for the input and output file names cout » input_file; cout > output_file; 10 11 12 13 14 // Construct the streams for reading and writing ifstream in(input_file); ofstream out(output_file); 15 16 17 18 // Check for errors and format the output stream if (in.fail() || out.fail(O) { return - 1; } out > value) { out <« setw(15) <« value <« endl; total = total + value; } 26 27 28 29 30 31 32 33 out << setw(8) << total « endl; 34 35 return 0; 36 }Please code in C++ and no other language#include <string>#include <iostream>#include <iomanip>#include <fstream>#include <vector>using namespace std; int main() { /* TODO: Declare any necessary variables here. */ /* TODO: Read a file name from the user and read the tsv file here. */ /* TODO: Compute student grades and exam averages, then output results to a text file here. */ return 0;}
