c语言统计输入字符数及行数

#include <stdio.h>
#define STOP ‘|‘

int main(void)
{
    char ch;
    int chnum = 0;
    int lines = 0;
    
    while((ch = getchar()) != STOP)
    {
        if(ch != ‘\n‘)
            chnum++;
        else
            lines++;
    }
    
    printf("ch number: %d.\n", chnum);
    printf("lines    : %d.\n", lines + 1);
    
    return 0;
}
