The correct answer is: A. template<\/strong><\/p>\n A template function is a function that can be used with different types of data. The type of data that a template function can be used with is called a generic type. Each generic type in a template function definition is preceded by the keyword For example, the following is a template function that can be used with any type of data:<\/p>\n This function can be used to add two integers, two floats, or two strings. For example, the following code calls the The And the The The [amp_mcq option1=”template” option2=”function” option3=”type” option4=”class” correct=”option1″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[683],"tags":[],"class_list":["post-56561","post","type-post","status-publish","format-standard","hentry","category-object-oriented-programming-using-c-plus-plus","no-featured-image-padding"],"yoast_head":"\ntemplate<\/code>.<\/p>\nc++
