C program for counting characters, words, and lines in a text

In this tutorial, we are going to write a C Program for counting characters, words, and lines in a text in C Programming with practical program code and step-by-step full complete explanation.

C Program for counting characters words and lines in text.

 
#include<stdio.h>
#include<conio.h>
#include<string.h>

void main()
{
    char line[81],ctr;
    int i,c,end=0,characters=0,words=0,lines=0;

    printf("KEY IN THE TEXT");
    printf("GIVE ONE SPACE AFTER EACH WORD WHEN COMPLETED, PRESS RETURN");

    while(end==0)
    {
        c=0;

        while((ctr=getchar()) !='\n')
            line[c++]=ctr;

        line[c]='\0';

        if(line[0]=='\0')
            break;
        else
        {
            words++;

            for(i=0;line[i]!='\0';i++)
                if(line[i]==' ' || line[i]=='\t')
                    words++;
        }
        lines=lines+1;
        characters=characters + strlen(line);
    }

    printf("\n");
    printf("Number of lines=%d",lines);
    printf("Number of words=%d",words);
    printf("Number of characters=%d",characters);
}

Output

 
KEY IN THE TEXT
GIVE ONE SPACE AFTER EACH WORD WHEN COMPLETED, PRESS RETURN

Admiration is a very short lived passion.
Admiration involves glorious obliquity of vision.
Always we like those who admire us but we do not like those wo we admire.
Fools admire, but men of sense approve

Number of lines=4
Number of words=36
Number of characters=205
