std::cout<<"\n being used within C++ code\n"; } int main(void) { f(); func(); return 0; } The C function f() is declared within the notation extern “C” to tell the cpp compiler that it has C type linkage. Now,
Here’s an example of a float to int conversion using a C-style cast: #include <iostream> #include <string> #include <vector> using std::cout; using std::endl; using std::vector; int main() { vector<float> f_vec{12.123, 32.23, 534.333333339}; vector<int> i_vec; i_vec.reserve(...
