You can traverse and print a map as well as an unordered map using iterators in a loop. You can define an iterator as given below. Iterator for map: map iterator 1 2 3 map<type, type>::iterator name; Iterator for unordered map: unordered map iterator 1 2 3 unordered_map<type...

The auto keyword instructs the compiler to automatically detect the data type of the array variables. Output: 2.4 4.5 1.5 3.5 4 6.7 print array in C++ Using Iterators Iterators are one of the four pillars of the C++ Standard Template Library, also known as the STL. An iterator points to...
C++ STL Vector: Here, we are implementing a program in which we are declaring a float vector, pushing the elements and printing the elements. Submitted by IncludeHelp, on June 18, 2019 Push and print elements in a float vectorIn this example, we are declaring a float vector and pushing ...
printf has the variable number of parameters, and it takes string variable as char * type, which means we have to call the c_str method from s1 variable to pass it as an argument. Note that each type has its format specifier (e.g., string - %s), which is listed in the following ...

strings. The concatenation operator evaluates each expression, and if an expression is not a string, it gives an error. So we need to explicitly cast an expression that is not of the string data type. We can type cast it by using thestr(var)method. Thevaris the variable that is not a...
