When calling a function, to save these values, you must use the following syntax: local a, b, c = triple (5) Which will result in a = b = c = 5 in this case. void Getinfo(int *age, float *height, char *name) {. Using output parameters: auto output_1(int &i1) { i1 = 11; return 12; } Using a local structure: auto struct_2() { struct _ { int i1, i2; }; return _{21, 22}; } Using an std::pair: auto pair_2() { return std::make_pair(31, 32); } Using an std::tuple: #include <stdlib.h>. printf("\nThe greater number is %d and the". C++, Returning multiple values from a C++ function Author: Erika Hoover Date: 2022-08-03 You either return a or as the return value, or you pass in reference values or pointers and the function sets the referred to/pointed to value. Consider the following code from the console application. Instead of assigning the return values to a single tuple, let's unpack our tuple and return three separate values. 2. Then we must pass the parameters x and y values with c and d by call by address. The return statement can be skipped only for void types. Maximum element is 20, Minimum - 1 Use Array to Return Multiple Values From a Function in C++ Alternatively, we can declare a C-style array to store and return multiple values from the function. Methods not returning a value: In C/C++ one cannot skip the return statement, when the methods are of return type. As the name suggests, they are passed as reference to the function and after the function executes, the updated value of the passed reference variable is returned back to the calling method. Returning multiple values using an array (Works only when returned items are of same types): When an array is passed as an argument then its base address is passed to the function so whatever changes made to the copy of the array, it is changed in the original array. There is no specific syntax for returning multiple values, but these methods act as a good substitute How many values can a CPP function return at a time? Answer (1 of 3): Re "Is there a way to return multiple values in C++ just by calling by reference and no arrays or struct?": Yes. I was happy to find out that since C++11 there is support for a fixed-size collection of heterogeneous values called tuple. Since one of your result types is a string (and you're using C, not C++), I recommend passing pointers as output parameters. This need of disambiguating several return values of the same type sounds very similar to the one of clarifying the meaning of a function's parameters, which we . v. t. e. ESG ( Environmental, social, and corporate governance) is an umbrella term that refers to specific data designed to be used by investors for evaluating the material risk that the organization is taking on based on the externalities it is generating.
