C++ construct vector from char array
WebIn the above program, two strings are asked to enter. These are stored in str and str1 respectively, where str is a char array and str1 is a string object. Then, we have two functions display () that outputs the string onto the string. The only difference between the two functions is the parameter. The first display () function takes char array ... WebConvert a vector into an array using STL Algorithm copy () Create an array of same size as the vector. Then pass the vector elements as range [start, end) to the copy () function as initial two argument and as the third argument pass the iterator pointing to the start of array. It will copy all the elements of vector into the array.
