We then use a range-based for loop to iterate over each element in the numbers vector: In the loop header int number : numbers means that for each iteration, the current element from the numbers vector will be assigned to the variable number. During each iteration, the value of number is...
no_vector 默认情况下,自动向量化会尝试向量化其计算为可能从中受益的所有循环。 请指定此 pragma 以对其后面的循环禁用自动向量化。 ivdep 指示编译器忽略此循环的向量依赖项的提示。 备注 若要使用 looppragma,请将其放在紧靠循环定义之前,而不是放在循环定义中。 pragma 对它后面的循环的范围有效。 可按任意顺序将...
