template<class out_type,class in_value> out_type convert(const in_value & t) { stringstream stream; stream<<t;//向流中传值 out_type result;//这里存储转换结果 stream>>result;//向 result 中写入值 return result; } 这样使用 convert(): double d; string salary; string s=”12.56”; d=...
C++标准库中的<sstream>提供了比ANSI C的<stdio.h>更高级的一些功能,即单纯性、类型安全和可扩展性 定义一个通用的转换模板,用于任意类型之间的转换。函数模板convert()含有两个模板参数out_type和in_value,功能是将in_value值转换成out_type类型: template<class out_type,class in_value> out_type convert(co...
static stringstream ss (stringstream::in | stringstream::out); 的Token.h中的 error C2061: syntax error : identifier 'in' 和2010年的视觉工作室用红色 stringstream::in | 强调
I test that stringstream class has similary performance with sprintf in the single-thread mode. In multithread mode, sprintf has almost the same execution time, but the execution time of each thread using string stream increased linearly as the thread number increased. ...

I am writing a C/C++ program that runs in background (Linux). Therefore, normally no output would be written into standard output. However, sometimes I want to have debug message collected and sent tho network to a client so that errors and debug message
