Question

Write a program to read in the file below and count the number of sentences, and the number of each sentence terminators noted in the next statement. A sentence ends with a '.', ';', '?', or '!'.

The name of the file should be a command line parameter to your program called terminatorCounters.

Just a little confused on how to get started here.

the file is just a text file.

Answer 1

/*terminatorCounters.c*/
#include <stdio.h>

int main(int argc, char *argv[])
{
FILE *fp;
char *filename;
char ch;
int line_count = 1;
int terminator_count =0;
  
//Check if the argument has Filename
if (argc < 2)
{
printf("No file name in the command line argument");
return(0);
}
  
filename = argv[1];
printf("Name of the file: %s\n", filename);
  
// Opening the file in read only mode
fp = fopen(filename,"r");

// If file opened successfully, extract characters from file and store in character ch
if ( fp )
{
for ( (ch = fgetc(fp)); ch != EOF ; ch=getc(fp))
{
//Counting number of sentences
if (ch == '\n'){
line_count = line_count + 1;
}
//Counting number of sentence terminator
if ((ch == '.' || ch == '?' || ch == ';' || ch == '!')){
terminator_count = terminator_count + 1;
}
}
  
printf("Total number of sentences %d \n ", line_count);
printf("Total number of terminator characters %d \n ", terminator_count);
}
else
{
printf("Unable to open the file\n");
}
// Close the file
fclose(fp);
  
return(1);
}
