Please write the code in c++
Write a function with one input parameter that is a vector ofstrings. The function should count and return the number of stringsin the vector that have either an 'x' or a 'z' character inthem.
For example, when the function is called, if the vector argumentcontains the 6 string values, \"enter\", \"exit\", \"zebra\", \"tiger\",\"pizza\", \"zootaxy\" the function should return a count of 4.(\"exit\", \"zebra\", \"pizza\", and \"zootaxy\" all have an x and/or a zcharacter.)
You may assume all letters in the vector of strings arelowercase and that the vector can have a large number ofelements.
