Question

In C write a text analyzer program that reads any text file. The program displays a menu that gives the user the options of counting: • Lines • Words • Characters • Sentences (one or more word ending with a period) • or all of the above Provide a separate function for each option. At the end of the analysis, write an appropriate report.

Solution:

TextAnalyser.c:

#include <stdio.h>
#define FILE_NAME 50
FILE *fp;
void countLines(char filename[]) {
   char c;
   int linecount = 0;
   for (c = getc(fp); c != EOF; c = getc(fp))
if (c == '\n')
linecount = linecount + 1;
printf("\nThe file %s has %d lines", filename, linecount);
}
void countWords(char filename[]) {
   char c;
   int wordcount=1;
   c=fgetc(fp);
while(c!=EOF)
{
if(c==' '||c=='\n')
{
wordcount++;
}
c=fgetc(fp);
}

   printf("\nThe file %s has %d words", filename, wordcount);
}
void countCharacters(char filename[]) {
   char c;
   int charactercount = 0;
   while ((c=getc(fp)) != EOF) {
       if (c != ' ' || c != '\n') {
           charactercount += 1;
   }
   }
printf("\nThe file %s has %d characters", filename, charactercount);
}
void countSentences(char filename[]) {
   char c;
   int sentencecount = 0;
   while ((c=getc(fp)) != EOF) {
       if (c == '.' || c== '!' || c=='?') {
           sentencecount += 1;
   }
   }
printf("\nThe file %s has %d sentences", filename, sentencecount);
}

int main()
{
char filename[FILE_NAME];
printf("Enter file name: ");
scanf("%s", filename);
fp = fopen(filename, "r");
  
// Check if file exists
if (fp == NULL)
{
printf("Could not open file %s", filename);
return 0;
}
int choice;
printf("1.Lines\n2.Words\n3.Characters\n4.Sentences\n");
printf("Enter your choice: ");
scanf("%d", &choice);
switch(choice) {
       case 1: countLines(filename);
               break;
       case 2: countWords(filename);
               break;
       case 3: countCharacters(filename);
       break;
       case 4: countSentences(filename);
               break;
       default: printf("\n please enter correct choice!");
               break;
           }
             
// Open the file
  
// Extract characters from file and store in character c
  
  
return 0;
}

Ants are found everywhere in the world. They make their home in buildings, gardens etc. They live in anthills. Ants are very hardworking insects. Throughout the summers they collect food for the winter season. Whenever they find a sweet lying on the floor they stick to the sweet and carry it to their home. Thus, in this way, they clean the floor.Ants are generally red and black in colour. They have two eyes and six legs. They are social insects. They live in groups or colonies. Most ants are scavengers they collect whatever food they can find. They are usually wingless but they develop wings when they reproduce. Their bites are quite painful.
