In C Programming Language, write a command line argument(s) program. The line should have program_name.exe input_file1.txt “char_string”. The program should print an error message if there are not exactly three arguments on the line. input_file1.txt will have a word in it different than the “char_string”. The program will print on one line the char_string concatenated with input_file1.txt followed by the program name. Upon success print on new line, “Program finished!”
#include <stdio.h> #include <stdlib.h> #include <string.h> int main(int argc, char *argv[]) { int* arr1; int i = 0; char line[1000]; FILE *fptr; if(argc == 3){ if ((fptr = fopen(argv[1], "r")) == NULL) { printf("Error! opening file"); exit(1); } printf("%s\n",argv[2]); while (fgets(line, sizeof line, fptr) != NULL) { printf("%s",line); } printf("Program finished!\n"); fclose(fptr); } else{ printf("Error: Please provide 3 command line arguments\n"); } return 0; }
In C Programming Language, write a command line argument(s) program. The line should have program_name.exe input_file1.txt...
Problem: Write a program that behaves as described below.If the first command-line argument after the program name (argv[1]) is “--help”, print the usage information for the program. If that argument is not “--help”, you are to expectargv[1]and subsequent arguments to be real numbers(C, integer, float, or double types)in formats acceptable to the sscanf()function of the C library or strings of ASCII chars that are not readable as real numbers. You are to read the numbers, count them and calculate the...
Write a program that will accept two integers on command line, use the swap subprogram to swap them, and then print the two numbers out. For example, I enter a.out 10 15 and the output that would print is 15 10. Please note that if exactly two numbers are not provided on command line, your program should display an error message and end with no further action. The programming language is C Compiler.
Objective: Use input/output files, strings, and command line arguments. Write a program that processes a text file by removing all blank lines (including lines that only contain white spaces), all spaces/tabs before the beginning of the line, and all spaces/tabs at the end of the line. The file must be saved under a different name with all the lines numbered and a single blank line added at the end of the file. For example, if the input file is given...
C Language Programming. Using the program below - When executing on the command line only this program name, the program will accept keyboard input and display such until the user does control+break to exit the program. The new code should within only this case situation “if (argc == 1){ /* no args; copy standard input */” Replace line #20 “filecopy(stdin, stdout);” with new code. Open read a text file “7NoInputFileResponse.txt” that contains a message “There were no arguments on the...
Command Line Arguments: Write a program in C Compiler that will accept two integers on command line, subtract the second from the first (1st - 2nd) and display the answer. It exactly two numbers are not provided on command line, there should be a simple error message printed and the program ends with no further input, output, or calculations
Write a full program that will accept any number of command line arguments and print them to the screen. Suppose your program is called Print.java. When the command java Print hello goodbye you is run, the output will be hello goodbye you Write a full program that will accept exactly three command line arguments that can be interpreted as integers, and will add them up. If there aren't exactly 3 command line arguments, print an error message and terminate the program....
C Programming Language on Linux - Word Frequency Program Please write a Program in C that will accept a text file name as a command-line argument via a main program that will do the following: First, read the file (first pass) and create a linked list of words (in their order of occurrence), with the frequency of each word set to 0. Then, read the file (second pass) and for each word identified, search the linked list, and when found,...
Write a program that determines if a string (passed as a command-line argument) has all unique characters. The program must print the number of times each existing character appears, and then print whether or not they are all unique. Special requirements: You are NOT allowed to modify the input string or create any additional data structures (no arrays, lists, dictionaries, or other strings). You may have only one string (the one received as the command-line argument). You may have one...
1. Write a complete C++ program named “CheckAmount” that accepts command line arguments. It checks whether there is a command line argument of “-amount” followed by an amount number. It will print out that number amount. For all other cases, it will print out -1. For example, if you run this program with correct arguments as follows, it will print out 1.99, 0.75 and 1.1 respectively CheckAmount -amount 1.99 CheckAmount -help -amount 0.75 CheckAmount -help -check -amount 1.1 -verbose And...
In c programming, I need to write a program that reverses each of the lines in a file. The program accepts two command line arguments: The first one is the name of the input file The second is the name of the output file If the user didn't give two filenames, display an error message and exit. The program reads in each line of the input file and writes each line in reverse to the output file. Note, the lines...
