少数错误

本文介绍了少数错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

有人有兴趣快速看一下。编译器 给了我很多错误，我不知道从哪里开始。这是我第一次使用 isalpha。 #include< stdio.h> #include< stdlib。 h> #define ex exit（EXIT_FAILURE） int main（int argc，char * argv []） { if（argc！= 4）{ puts（print usage error）; ex; } if（isalpha（argv [1]）|| isalpha（argv [2]））{ puts（" name is 3rd arg"）; ex; } double x，y; FILE * fp; x = strtod（argv [1]，NULL）; y = strtod（argv [2]，NULL）; if（fp = fopen（argv [3] ，a）） == NULL）{ puts（fopen error）; ex; } fprintf（argv [3]，"％。2f"，x，y）; if（fclose（fp）） == NULL）{ puts（fclose error）; ex; } 返回0; } 我不知道感叹.. Bill

Would anyone be interested in giving this a quick look. The compiler gave me so many errors I don''t know where to start. This is my first use of isalpha. #include <stdio.h> #include <stdlib.h> #define ex exit(EXIT_FAILURE) int main(int argc, char *argv[]) { if (argc != 4) { puts("print usage error"); ex; } if (isalpha(argv[1]) || isalpha(argv[2])) { puts("name is 3rd arg"); ex; } double x, y; FILE *fp; x = strtod(argv[1], NULL); y = strtod(argv[2], NULL); if (fp = fopen(argv[3], "a")) == NULL) { puts("fopen error"); ex; } fprintf(argv[3], "%.2f", x, y); if (fclose(fp)) == NULL) { puts("fclose error"); ex; } return 0; } I dunno sigh..

也许您应该考虑发布您收到的错误...

Perhaps you should consider posting the errors you received...

看到大量错误并不罕见。从第一个 错误开始向下工作，这就是编译器遇到它们的方式。 专注，专注，专注！ 我已经标记了我在修复通常的互联网修改后找到的第一个。

It is not unusual to see a huge number of errors. Start with the first error and work downward, that''s the way the compiler encountered them. Focus, focus, focus! I have marked the first one I found after fixing the usual internet munging.

***额外''）''上面

*** extra '')'' above

puts（" name is 3rd arg"） ; ex; } double x，y; FILE * fp; x = strtod（argv [1]，NULL）; y = strtod（argv [2]，NULL）; if（fp = fopen（argv [3 ]，a）） == NULL）{ puts（fopen error）; ex; } fprintf（argv [3]，"％。2f"，x，y）; if（fclose（fp）） == NULL） { put（fclose error）; ex; } 返回0; } 我不知道感叹.. 比尔 puts("name is 3rd arg"); ex; } double x, y; FILE *fp; x = strtod(argv[1], NULL); y = strtod(argv[2], NULL); if (fp = fopen(argv[3], "a")) == NULL) { puts("fopen error"); ex; } fprintf(argv[3], "%.2f", x, y); if (fclose(fp)) == NULL) { puts("fclose error"); ex; } return 0; } I dunno sigh..
