//input.c中要处理的情况如下
input.c
// /*1234567890*/
源文件annotationconvert.c
#include #include #include #pragma warning(disable:4996) typedef enum state { file_error, //文件错误 file_success, //文件成功 other_error, //其他错误 no_match, //文件不匹配 }sta; typedef enum tag { tag_begin, //注释中 tag_end, //不在注释中 }tag; sta annotationconvert(file* infile, file* outfile) { char firstch, secondch; int next; assert(infile); assert(outfile); tag a = tag_end; do{ firstch = fgetc(infile); switch (firstch) { case'/': secondch = fgetc(infile); if (secondch == '*' && a == tag_end) { fputc('/', outfile); fputc('/', outfile); a = tag_begin; } else if (secondch == '/') { fputc(firstch, outfile); fputc(secondch, outfile); next = fgetc(infile); while (next != eof && next != ' ') { fputc(next, outfile); next = fgetc(infile); } a = tag_end; } else { fputc(firstch, outfile); fputc(secondch, outfile); } break; case'*': secondch = fgetc(infile); if (secondch == '/') { fputc(' ', outfile); a = tag_end; } else if (secondch == '*') { fputc(firstch, outfile); fseek(infile, -1, seek_cur); } else { fputc(firstch, outfile); fputc(secondch, outfile); } break; case' ': if (a == tag_begin) { fputc(firstch, outfile); fputc('/', outfile); fputc('/', outfile); } else { fputc(firstch, outfile); } break; default: fputc(firstch, outfile); break; } } while (firstch != eof); if (a == tag_end) { return file_success; } else { return no_match; } return 0; } sta startconvert() { sta s; const char* infilename = input.c; const char* outfilename = output.c; file* infile = fopen(infilename, r); file* outfile = fopen(outfilename, w); if (infile == null) { return file_error; } if (outfile == null) { fclose(infile); return file_error; } s = annotationconvert(infile, outfile); fclose(infile); fclose(outfile); return s; } int main() { sta ret = startconvert(); if (ret == file_error) { printf(文件错误:%d , errno); } else if (ret == file_success) { printf(转换成功 ); } else if (other_error) { printf(其他错误:%d , errno); } else { printf(不匹配 ); } return 0; }output.c中结果应如下:
//int i = 0;
//int y = 0;
int j = 0;
//int x = 0;/*12345678
//
//int h = 0;
//int g = 0;
//int j = 0;
//
int q = 0;
//
//
// ******
// /*1234567890*/
