Problem Statement - Displaying three character words in a file

Write a program to display all the words in a file that are three character words. Assume that filename is
MATTER.TXT and it contains the following matter.

The quick brown fox jumps over a lazy dog

Solution

TC++ #5044

 

Run Output

The fox dog

ifstream ipfile(“MATTER.TXT”,ios::in); //Opening the file using the ifstream class
if(!ipfile) {cout<<“Unable to open file”<<endl; return 1;} //Checking for presence of file
while(!ipfile.eof()) {// Loop till end of file is reached
char word[50]=””; //Here we initialise word variable with every loop. This ensures that loop works well till the last word.
ipfile>>word; //A word is collected from the file
if(strlen(word)==3) cout<<word<<” “; //Word with three character is displayed
}
ipfile.close(); //Closing file

Notes

  • This code can be tested on your local system only once a file with given content is created with its name as MATTER.TXT
  • It is always a good practice to check if the file has been opened properly. It will not open properly in many cases. One can reach the OS by returning an error to the operating system.
  • For DOS testing with TurboC environment, learners are advised to keep the input file in the BIN directory are the turboc program runs from there.
