There are two options to store strings in C++ The rst is the way done in C now called C-strings A C-string is stored as a sequence of chars terminated by the null character (which is denoted ’0’ and has value 0 as an int) The user must ensure that the null terminator remains present
printf(Value of mean: f ” mean); } Structs structs are a method of constructing new datatypes -store a collection of values together in memory ?elds-similar to a Java class but no methods-individual values are referred to using the “ ” operator-can use typedef to rename and turn struct tag into a “type” typedef struct Cat Cat; or

There are two ways to access fields within a struct Field within a struct can be accessed using the dot operator However if a pointer to the struct is given then we can access fields within the struct using -> operator For example node mynode; node* ptr = &mynode; ptr var1 = 100; ptr var2 = malloc(20);
Is it possible to print a struct in C?
You can create a function which knows how to print a struct ABC with the desired format, but it will not know how to print some other struct type. The format string should be "%d %c %ld" to match the actual arguments. Answer to the actual question is no, C has no "introspection" capability to figure out at runtime what a struct is made up of.
How to print C structs using Arduino?
You can't simply use Arduino's print to print C structs. You can only print simple C data types like float, String, int, etc. So you need to print each field of your struct separately. I don't know decode_results but you can print its fields with something like this:
How to print the value of a struct?
When printing a variable, you must always use the correct format specifier, so that it matches the type of the variable. However, there is no format specifier for user-defined types, such as struct date. Therefore, if you want to print the value of a struct, you must decide yourself how you want to print it.
What is struct in C++ with example?
The struct is a keyword of C++ language. A structure tag or name follows which is book in this case. Opening brace indicates the beginning of the structure. Thereafter, fields of the record or data elements are given one by one. The variables or fields declared are also called members of the structure.
