Then we print that value and return from the main function, which ends our program. Syntax for variable definition in C# is − Here, data_type must be a valid C# data type including char, int, float, double, or any user-defined data type, and variable_list may consist of one or more identifier names separated by commas. You could do this by returning all the values in an array, or by accepting variable references as parameters and modifying those. The idea is to create a struct containing all required data types as its members and return that struct from our function. Notice that inside function func_2() there is a local variable with the same name as a global variable. Using reference parameters in C++. Also, they may or may not return any values. Since sumDigits returns a value(the value of the sum variable), a value will appear in the place where the function was called. So in simple words, Functions can’t return arrays in C. However, inorder to return the We can use pointers in C to return more than one value from the function by passing pointers as function parameters and use them to set multiple values, which will then have visibility in the caller function. Some valid variable definitions are shown here − You can initialize a variable at the time of definition as − But fortunately, with a little bit of clever programming, we can easily achieve this. hello.c:5:10: warning: address of stack memory associated with local variable 'name' returned [-Wreturn-stack-address] return name; ^~~~ 1 warning generated.

While this program is a good attempt at a solution, it doesn’t quite work. Notice that the addresses of a, b and c variables are same before and after the modification.. For example, if you use “return a,b,c” in your function, value for c only will be returned and values a, b won’t be returned to the program. For example, consider the following program where f() is called once from main() and then from g().Each call to f() produces a different scope for its parameter p. If we use the static array, it ceases to exist when we exit from the function and accessing it inside the caller function will result in undefined behavior. But programmers often need to return multiple values from a functions. 2) Static variables are allocated memory in data segment, not stack segment. However, if the variables are in different scope then the addresses may or may not be the same in different execution of that scope.
