在C或C++编程中,当我们看到警告“warning: comparison between signed and unsigned integer expressions [-Wsign-compare]”时,这通常意味着我们正在将一个有符号整数(signed integer)与一个无符号整数(unsigned integer)进行比较。下面我将根据你的要求,详细解释这个警告的相关内容。 1. 解释"signed"和"unsigned"整数...
A warning - comparison betweensignedandunsignedinteger expressions [-Wsign-compare]1vector<int> histogram =Histogram(img);inttotal =0;for(inti =0; i != histogram.size(); ++i) { total += histogram[i]; }123456 警告的意思是一个无符号数整型与有符号整型最好不要比较。i是有符号整型,histogram....
这是个一般性质的警告, 只是提示你代码中存在 有符号和无符号的整型数据进行逻辑运算.这种警告是完全可以无视的, 因为编译器会自动处理的.
Comparison Between Signed and Unsigned Integer Expressions in C++ C++ supports signed and unsigned integers, which are written asintandunsigned int. When using signed integers, you can use the relational operators to compare two values. The relational operators will not work because they always evaluat...

warning: comparison between signed and unsigned integer expressions [-Wsign-compare] I thought I could safely ignore these, since it seems plausible to compare a signed value with an unsigned value. A signed value of -42 should be less than an unsigned value of 42, right?
