Theset::find() functionis a predefined function, it is used to check whether an element belong to the set or not, if element finds in the set container it returns an iterator pointing to that element. The funct

// 创建一个 set 集合容器 vector<int> myVector; // 向容器中插入元素 myVector.push_back(9); myVector.push_back(5); myVector.push_back(2); myVector.push_back(2); myVector.push_back(7); 然后, 调用adjacent_find 函数 , 将 vector 单端数组 容器的 begin 和 end 作为迭代器范围传入到函数...

If you need to have binutils first in your PATH, run: echo 'export PATH="/usr/local/opt/binutils/bin:$PATH"' >> ~/.zshrc For compilers to find binutils you may need to set: export LDFLAGS="-L/usr/local/opt/binutils/lib" export CPPFLAGS="-I/usr/local/opt/binutils/include" ==>...
简单来说就是math.hpp里定义了加法函数和减法函数,main.cpp里调用了这两个函数进行测试。 我们主要看CMakeLists.txt的内容: cmake_minimum_required(VERSION 3.10) project(course_07) set(INCLUDE "include") #set(CMAKE_INSTALL_PREFIX ${CMAKE_CURRENT_LIST_DIR}/install) add_library(add) target_sou...

bitset中_Find_first()与_Find_next()函数 很有趣~~但是没怎么有用~~的两个函数。 就是找到从低位到高位第一个1的位置 cpp include int main() { std::bitset B; B.set(2); B.set(4); B.set(233); std
