C Program 12

Write a program which takes a file as command line argument and copy it to another file. At the end of the second file write the total i) no. of chars ii) no. of words and iii)no. of lines

Source Code

//Program with File Location

#include <stdio.h>

int main(int argc,char * argv[])
{
FILE *ptr1, *ptr2;
char ch;
int letters=0,words=0,lines=0;
    // Opening file1 in reading mode
ptr1 = fopen(argv[1], "r");
if (ptr1 == NULL) {
printf("file1 can't be opened \n");
}
    // Opening file2 in write mode
ptr2 = fopen("C:\\Users\\Admin\\Desktop\\sample.txt", "w");
if (ptr2 == NULL) {
printf("file2 can't be opened \n");
}
// copying contents from one to another file
while((ch= fgetc(ptr1)) != EOF){
//ch = fgetc(ptr1);
fputc(ch,ptr2);
//count characters
   letters++;
        /* Check new line */
        if (ch == '\n' || ch == '\0')
            lines++;
        /* Check words */
        if (ch == ' ' || ch == '\t' || ch == '\n' || ch == '\0')
            words++;
  }
  if(letters>0)
    {
        words++;
        lines++;
    }
    fprintf(ptr2,"\nTotal Number of Characters:");
    fprintf(ptr2,"%d",letters);
    fprintf(ptr2,"\nTotal Number of Words:");
    fprintf(ptr2,"%d",words);
    fprintf(ptr2,"\nTotal Number of Lines:");
    fprintf(ptr2,"%d",lines);
    printf("Contents written in sample.txt file successfully");
// Closing the file
    fclose(ptr1);
fclose(ptr2);
    getch();
return 0;
}

//Program without File Location

#include <stdio.h>

char ch;
int letters=0,words=0,lines=0;
    // Opening file1 in reading mode

}
// copying contents from one to another file

fputc(ch,ptr2);
//count characters
   letters++;
        /* Check new line */
        if (ch == '\n' || ch == '\0')
            lines++;
        /* Check words */
        if (ch == ' ' || ch == '\t' || ch == '\n' || ch == '\0')
            words++;
  }
  if(letters>0)
    {
        words++;
        lines++;
    }
    fprintf(ptr2,"\nTotal Number of Characters:");
    fprintf(ptr2,"%d",letters);
    fprintf(ptr2,"\nTotal Number of Words:");
    fprintf(ptr2,"%d",words);
    fprintf(ptr2,"\nTotal Number of Lines:");
    fprintf(ptr2,"%d",lines);
    printf("Contents written in sample.txt file successfully");
// Closing the file
    fclose(ptr1);
fclose(ptr2);
    getch();
return 0;
}

Output:
Contents written in sample.txt file successfully
