In this tutorial we will see how to make a simple calculator using switch case statements in Go programming language. The switch statement will assess an expression, comparing the expression's value against a series of case conditions given in a series and executes the statement after the first condition with a matching value, until a break is encountered. Golang Basic switch case with default A switch statement runs the first case equal to the choice entered. The cases are evaluated in an order and it stops when a case succeeds. If no case (choice entered) matches, it is a ... Read More

In this tutorial we will learn how to create a function without argument and without a return value in Go Programming Language. When a function has no arguments, it does not receive any data from the calling function. Similarly when it does not return any value, the calling function does not receive any data from the called function. So there is no data transfer between calling and called function. Add two Numbers Algorithm Step 1 − Import the package fmt package Step 2 − Start function main () Step 3 − Calling the function add () Step 4 − ... Read More

In this tutorial we will discuss how to write a Golang program to find the greatest common divisor GCD using recursion. The greatest common divisor (GCD) of two or more numbers is the greatest common factor number that divides them, exactly. It is also called the highest common factor (HCF). For example, the greatest common factor of 15 and 10 is 5, since both the numbers can be divided by 5. 15/5 = 3 10/5 = 2 Algorithm Step 1 − Import the package fmt Step 2 − Start function main() Step 3 − We will use an ...
