Section 1.5.2 Character Counting2¶
Program¶
#include <stdio.h>
/* count characters in input; 2nd version */
int 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.
