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....
The error I am getting is:Warning: comparison between signed and unsigned integer expressions (line 9).I also tried writing a new code then to see whats causing the problem: #include<iostream>#include<cstring>voiddisplay1(){charmessage[] ="Hello, world!";for(inti =0; i <sizeof(message...
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.

When designing functions that accept integer parameters, the choice between signed and unsigned types influences the function’s behavior and flexibility. Example: Function Parameter voidprintValue(intvalue){// Function body} Usingintas the parameter type implies that negative values are valid inputs. ...
What is assumed to be the preferred way to fix "comparison between signed and unsigned integer" warnings safely? In my case I have to compare some uint_32 variables with #define constants. Really simplified: #define MAX(A,B) ({ __typeof__(A) __a = (A); __typeof...
