Define Function:A functiongreetis defined, which takes a string parameter and prints a greeting message. Assign to Variable:The functiongreetis assigned to the variablegreetPointer. Call Function:The function is called usinggreetPointer, behaving the same as callinggreetdirectly. Output Example 2: Pa...
Go – Function Return In this tutorial, we will explore how to use return statements in functions in theGoprogramming language (Golang). Functions in Go can return values to the caller using thereturnkeyword. Go supports single, multiple, and named return values, making functions versatile and ...
What are anonymous functions in golang? In Golang, Anonymous function are special function created without the function name.It is useful when someone want to create an inline function.It can accept input and return output just like the standard function does. It is also known asfunction litera...
In this post, we'll learn how a function takes a slice parameter and returns a slice. Sample code #1 - Prime numbers In the following code, we'll try to get prime numbers up to 100. The function (getPrimes) takes a slice as its argument and gathers primes. Then, returning it to t...
We use an asterisk (*) before the parameter name to denote this kind of argument. For example, # program to find sum of multiple numbersdeffind_sum(*numbers):result =0fornuminnumbers: result = result + numprint("Sum = ", result)# function call with 3 argumentsfind_sum(1,2,3)# fu...

We pass a value to the function parameter while calling the function. int main() { int n = 7; // calling the function // n is passed to the function as argument printNum(n); return 0; } Example 2: Function with Parameters // program to print a text #include <iostream> using nam...
If the parameter is ±Inf, it returns the same (±Inf). Ceil(NaN) = NaN If the parameter is NaN (Not-A-Number), it returns the same (NaN). Example 1 // Golang program to demonstrate the// example of math.Ceil() Functionpackagemainimport("fmt""math")funcmain() { ...
Example 1: Golang pass nil as an argument In the below example, if the parameter iszero value, set it with the default value: package main import "fmt" func main() { fmt.Println(GetStudentInfo("", "")) fmt.Println(GetStudentInfo("Anna", "")) fmt.Println(GetStudentInfo("", "+...
