Section 1.5.2 Character Counting2

Program

#include <stdio.h>
/* count characters in input; 2nd version */
main()
{
    double nc;
    for (nc = 0; getchar() != EOF; ++nc)
        ;
    printf("%.0f\n", nc);
}

Explanation

In this program we are going to count the number of characters present in the input. The program does the counting by setting nc to 0 in the beginning. As the program enters for loop condition (nc = 0; getchar() != EOF; ++nc). When nc hits end of the document it prints the number of characters in the file.
