Programming Assignment # 1

C and UNIX



The purpose of this assignment is to get you more familiar with Unix/Linux and those constructs of C that are not part of C++.

Write a C program (on a Unix/Linux system) that counts and displays the number of words, non-white space characters, and/or lines in a text file. The name of the input file is to be provided to the program as a command line argument. In addition, the program takes option flags to determine what actions to take. The command format is as follows:

command [-clw] inputfile

where the presence of a flag indicates the following actions:


c: display the number of characters in inputfile.


l: display the number of lines in inputfile.


w: display the number of words in inputfile.

Solution:

#include
#include
#include
#define MAX_ROW 5
#define MAX_COL 80


void main(){
char name[MAX_ROW][MAX_COL],c;
int lines=1; //bcoz. first line will be left to count.int words=1; //bcoz. first word will be left to count.int chars=1; //bcoz. first char will be left to count.
clrscr();
cout<<"===Input Status===\n";
cout<<"Enter string termanate by # : ";
cin.get(c);

//Finding no. of lineswhile(c != '#'){
cin.get(c);
chars++;
if(c==' ' || c=='\n')
words++;
if(c=='\n')
lines++;
}
