c - 使 fscanf 忽略 int 前没有空格的字母

Question

我正在尝试(在 C 中)从包含以下行的文件中读取:

GFE_1GFE_8GFE_19 

I want to use fscanf to ignore the letters and _ and put the number at the end into a variable.

Obviously what I have isn't right:

fscanf(f, "%d", number);

如果它们被空格分隔，我知道如何跳过它们，但在这种情况下我被卡住了。

Answer 1

怎么样

fscanf(f, " %*[^A-Z]_%d", &number);

或者如果前导字符总是相同的，那么就很简单

fscanf(f, " GFE_%d", &number);
