if(ch == ''')
{
   word_len++;
}

如何指定何时ch等于'它添加一个word_len？似乎我只能使用上面的代码来指定它.

#include <stdio.h>
#include <math.h>

long factcalc(int num1);

int main(void) 
{
    int num1;
    long factorial;
    int d;
    int out;

    printf("Please enter a number that is greater than 0");
    scanf_s("%d", &num1);

    if (num1 < 0) {
        printf("Error, number has to be greater than 0");
    } else if (num1 == 0) {
        printf("\nThe answer is 1");
    } else {
        factorial = factcalc(num1);
        printf("\nThe factorial of your number is\t %ld", factorial);
    }

    return 0;
}

long factcalc(int num1) 
{
    int factorial = 1;
    int …
