#include <stdio.h>
/* count characters in input; 1st version */
main()
{
long nc;
nc = 0;
while (getchar() != EOF)
++nc;
printf("%ld\n", nc);
}
- Concepts: Increment operator; long types
- Increment (++) and decrement (-) operators can be prefix or postfix
#include <stdio.h>
/* count characters in input; 2nd version */
main()
{
double nc;
for (nc = 0; getchar() != EOF; ++nc)
;
printf("%.0f\n", nc);
}
- Concepts: Null statement
