Notepad++文本比较与合并工具 ### 2.1 Notepad++的文本比较功能 Notepad++的文本比较功能允许用户比较两个或多个文本文件,并突出显示差异。它提供了多种选项来定制比较过程,包括: - **比较模式:**允许用户选择比较文本文件的不同方式,例如逐行比较或逐字符比较。 - **忽略空白:**忽略比较中的空格和制表符,从而专注于文本内容的差异。 - **忽略大小写:**忽略比较中的大小写差异,从而专注于文本内容的语义差异。 - **自定义分隔符:**允许用户定义自己的分隔符,以将文本文件分解为可比较的块。 **代码块:** ```cpp // 比较两个文本文件 int CompareFiles(const char* file1, const char* file2) { // 打开两个文件 FILE* fp1 = fopen(file1, "r"); FILE* fp2 = fopen(file2, "r"); // 逐行读取文件 char line1[1024], line2[1024]; int lineNum = 0; while (fgets(line1, sizeof(line1), fp1) != NULL && fgets(line2, sizeof(line2), fp2) != NULL) { // 比较两行 if (strcmp(line1, line2) != 0) { printf("差异在第 %d 行:\n", lineNum); printf("文件 1: %s", line1); printf("文件 2: %s", line2); return 1; } lineNum++; } // 关闭文件 fclose(fp1); fclose(fp2); // 如果文件长度不同,则差异存在 if (feof(fp1) != feof(fp2)) { printf("差异在第 %d 行之后:\n", lineNum); return 1; } return 0; } ``` **逻辑分析:** 该代码块实现了逐行比较两个文本文件的功能。它使用 `strcmp` 函数比较两行文本,并打印差异行和差异文本。如果文件长度不同,它也会报告差异。 **参数说明:** - `file1`:要比较的第一个文本文件。 - `file2`:要比较的第二个文本文件。 ### 2.2 Notepad++的文本合并功能 Notepad++的文本合并功能允许用户合并两个或多个文本文件,并解决它们的差异。它提供了多种选项来控制合并过程,包括: - **合并模式:**允许用户选择合并文本文件的不同方式,例如逐行合并或逐字符合并。 - **优先级:**允许用户设置不同文本文件的优先级,以确定在合并时优先使用哪个文件的内容。 - **冲突解决:**允许用户定义在遇到冲突时如何解决冲突,例如使用第一个文件的内容或第二个文件的内容。 **代码块:** ```cpp // 合并两个文本文件 int MergeFiles(const char* file1, const char* file2, const char* outputFile) { // 打开三个文件 FILE* fp1 = fopen(file1, "r") ```
