基于GTK+的单词数值计算器

Linux综合性实验报告一 实验题目：基于GTK+的单词数值计算器二 实验任务要求：1、按照规则计算单词的值，如果A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 26个字母（全部用大写）的值分别为 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 ，如WINJACK这个单词的值就为W+I+N+J+A+C+K=23+9+14+10+1+3+11=71%HARDWORK= H+A+R+D+W+O+R+K = 8+1+18+4+23+15+18+11 = 98%KNOWLEDGE=K+N+O+W+L+E+D+G+E = 11+14+15+23+12+5+4+7+5 = 96%LOVE=L+O+V+E=12+15+22+5=54%LUCK=L+U+C+K = 12+21+3+11 = 47%ATTITUDE=A+T+T+I+T+U+D+E = 1+20+20+9+20+21+4+5 = 100%2、程序的界面布局参考如下图，在第一个单行文本框输入一单词，点击“计算”按钮，按照以上算法计算出该单词的值。3、如果在最下面的单行文本框输入一个文件路径，此文件每行记录一个单词，那么经过程序计算出各个单词的值，并把结果输出到当前目录下result.txt文件中。如果文件不存在，应该提示错误。三 程序代码:#include #include #include #include GtkWidget *entry_value;
