Question:10
Write a function in c++ named count_space() to read a file named “article.txt”. Count and print total spaces in the file.
Sol:
/* count total spaces in the file */
#include<iostream>
#include<fstream>
#include<conio.h>
#include<stdio.h>
#include<stdlib.h>
using namespace std;
void count_spaces()
{
ifstream pqr;
char ch;
int s=0;
pqr.open("article.txt");
if (pqr.fail())
{
cout<<"Unable to open the file"<<endl;
getch();
exit(1);
}
while(!pqr.eof())
{
pqr.get(ch);
if(ch==' ')
s++;
cout.put(ch);
}
pqr.close();
cout<<"total spaces = "<<s<<endl;
}
int main()
{
count_spaces();
return(0);
}
Question:11
Write a function in c++ named count() to read a file named “article.txt”. Count and print the following:
Total alphabets
Total upper case alphabets
Total lower case alphabets
Total digits
Total spaces
Total length of the file (total characters)
Sol:
#include<iostream>
#include<fstream>
#include<conio.h>
#include<stdio.h>
#include<stdlib.h>
using namespace std;
void count()
{
ifstream pqr;
char ch;
int c=0,a=0,ua=0,la=0,d=0,sp=0,spl=0;
pqr.open("article.txt");
if (pqr.fail())
{
cout<<"Unable to open the file"<<endl;
getch();
exit(1);
}
while(!pqr.eof())
{
pqr.get(ch);
if((ch>='A' && ch<='Z') || (ch>='a' && ch<='z'))
{
a++;
if(ch>='A' && ch<='Z')
ua++;
else
la++;
}
else
if(ch>='0' && ch<='9')
d++;
else
if(ch==' ')
sp++;
else
spl++;
c++;
cout.put(ch);
}
pqr.close();
cout<<"total length "<<c<<endl;
cout<<"total alphabets "<<a<<" upper "<<ua<<" lower "<<la<<endl;
cout<<"digits "<<d<<" space "<<sp<<" special chars "<<spl<<endl;
}
int main()
{
count();
return(0) ;
}
