Question
In C++, Write a program to read in a simple text file (let's call it "simplefile.txt") and:
find the number of characters in each word (save those values as a variable called "word"), the number of characters in each line (save those values as a variable called "line"), the number of characters in each sentence (save those values as a variable called "sent"), and the number of characters in each paragraph (save those values as a variable called "para").Please make the program as simple as possible and include comments illustrating the logic behind each step.
Explanation / Answer
#include<iostream.h>
#include<fstream.h>
#include<string.h>
#include<conio.h>
#include<stdio.h>
void countchar(char *filename)
{
ifstream fin(filename);
char ch;
std::string line;
int i,words=0,sent=0,lines=0;
int wc=0, lc=0, sc=0;
bool l=false, s=false;
while(fin.get(ch))
{
i=ch;
//cout<<ch;
if(i==' ')
{
words++;
cout << " word no "<<words<<" contains "<<wc<<" characters"<<endl;
wc=0;
}
else if (i == ' ')
{
// check if sentence is complete then count only line and not words
if(!s)
{
words++;
cout << "Word no "<<words<<" contains "<<wc<<" characters"<<endl;
wc=0;
}
lines++;
cout << "Line no "<<lines<<" contains "<<lc<<" characters"<<endl;
lc=0;
s=true;
}
else if (i == '.') // if character is . this marks end of sentence so display characters in sentence
{
words++;
cout << " word no "<<words<<" contains "<<wc<<" characters"<<endl;
wc=0;
sent++;
cout << "Sentence no "<<sent<<" contains "<<sc<<" characters"<<endl;
sc=0;
s=true;
}
else
{
wc++; lc++; sc++;
}
}
fin.clear();
}
int main()
{
char *filename="sent.txt";
char a;
countchar(filename);
return 0;
getch();
}
// Regarding paragraph, it depends on how you view paragraph. Isit new line or one empty line in between. Usually paragraphs start in new line so in that case.
