自己改一下,應(yīng)該沒有什么問題的,
使用fopen函數(shù)打開文件,使用fgetc()一個(gè)字符一個(gè)字符的讀取,然后計(jì)數(shù)統(tǒng)計(jì)就可以啦,fget()從文件指針stream指向的文件中讀取一個(gè)字符,讀取一個(gè)字節(jié)后,光標(biāo)位置后移一個(gè)字節(jié),這個(gè)函數(shù)的返回值,是返回所讀取的一個(gè)字節(jié)。如果讀到文件末尾或者讀取出錯(cuò)時(shí)返回EOF。

擴(kuò)展資料
1、源程序中,很多符號(hào)都是成對匹配出現(xiàn)的,為避免遺漏必須配對使用的符號(hào)。
2、用花括號(hào)括起來的部分,但從程序結(jié)構(gòu)清晰,便于閱讀、理解、維護(hù)的角度出發(fā),建議在書寫程序時(shí)應(yīng)遵循以下規(guī)則,以養(yǎng)成良好的編程習(xí)慣。
3、一個(gè)說明或一條語句占一行,與該結(jié)構(gòu)開始處的左花括號(hào)對齊。
希望對你有用
