WebAug 30, 2016 · (C_expect - C_actual).norm () < 1e-6 In a vector space X - Y == 0 if and only if X == Y, and the norm is always non-negative (real). This way, you won't have to manually do the loop and compare element-wise (of course the norm will perform more calculations in the background than simple element-wise comparisons) WebThe C++ function std::vector::operator== tests whether two vectors are equal or not.

It compares the two ranges for element-wise equality, and if all elements in two ranges are equal, it returns true, otherwise false. We can check if two strings are equal by providing both the strings as character range. For example, Example 1: Copy to clipboard #include
WebMar 14, 2010 · C++ and C (remove std:: for C): bool equal = (std::strcmp (charTime, buf) == 0); But the true C++ way: std::string charTime = "TIME", buf = "SOMETHINGELSE"; bool equal = (charTime == buf); Using == does not work because it tries to compare the addresses of the first character of each array (obviously, they do not equal).
WebMay 10, 2009 · The equality test is specific to the type of iterator you are using, or may not exist at all.
