Go Programming: Master the Basics with Ease

Explore variables in go as containers that label and store data values, declared with the var keyword, initialized or defaulted, and printed with fmt println.

Master short variable declaration in Go to declare and initialize values with type inference, using strings, ints, floats, and bools, and print results with fmt.Println.

Explore Go block declarations with var keyword or short variable declaration operator, declare mixed types, and print results with println while noting block scope to the function or package.

Go constants are immutable values declared with the const keyword and evaluated at compile time. The lecture demonstrates declaring a constant named test and printing it with println.

Define the integer data type in Go, representing whole numbers. Explore signed and unsigned integers, memory usage, and how static typing with the uint keyword enforces non-negative values.

Explore how the Go float datatype represents decimal numbers and enables arithmetic. Read about float32 for memory efficiency and float64 for higher precision.

Learn how the Go string data type represents sequences of characters, including double-quoted string literals, and how to declare, concatenate, and compare strings.

Master boolean data in Go by declaring with the bool keyword, using true or false, and applying and, or, and not for control flow decisions.

Explore the go fmt package and the print function, which outputs values to standard output without automatically adding newlines, with spaces or line breaks controlled by arguments.

Master the Go println function to print values to standard output with automatic newline and formatting; learn to combine variables in one call for a single line with spaces.

Master the printf function to format and print values to standard output in Go, with newline handling and percent v and percent t verbs.

Learn how to cast between int, float32, and float64 types in Go, including converting float32 to int, and print values and types with printf using %v and %t.

Learn how Go treats strings as immutable text, and use the Len function to measure length, with examples using fmt.Println to print results.

Explore string handling in Go by concatenating strings with the plus operator, printing results with printf, and ensuring spaces between strings on the console.

Learn how arithmetic operators in Go perform mathematical operations on integers, including addition, with a practical example that prints the result to the console.

Explore assignment operators in Go, update variables with addition and multiplication assignments, print results to the console, and learn to clear the console to see updated values.

Explore Go's comparison operators, including equality, not equal, greater than, less than, and their booleans. See println print true or false when comparing test and test1.

Learn how to use logical operators and, or, and not to combine conditions, and observe true or false results from comparisons like greater than and less than.

Explore bitwise operators in Go, perform and, or, xor, and shifts on integers, compare bits, convert between binary and decimal, with examples showing 12 and 10 yielding 8 and 14.

Explore conditional statements in Go by mastering the if condition, testing comparisons such as greater than and equality, and observing code execution inside the if block.

Discover how go's if-else controls flow by evaluating a condition and executing the if or else block, with syntax requiring else on the same line as the closing brace.

Explore go basics with else if conditions: evaluate if and else if statements, chain multiple else if blocks, and use else as default, with println output examples.

Explore nested if statements in Go, where an outer condition can trigger an inner one and guide execution through else or else if branches.

Use the Go switch statement to decide which code block to run based on an expression's value, with cases one, two, three, and an optional default, illustrated by examples.

Go arrays use contiguous memory to store fixed-size collections of the same type, declared with var or short syntax, initialized with int or string values, and printed with println.

Explore go array initialization by declaring a four-element string array with three values, the uninitialized slot yields an empty string, then convert an array to four ints to see zeros.

Explore Go array indexing by zero-based positions, using square brackets to access elements; see how index one yields 2 and index three yields 4, with console output confirming each access.

Update a Go array by index in a four-element int array; use zero-based indexing, set index 1 from 2 to 6, and print the updated contents to the console.

Learn to use the Len function to measure a Go array’s length and print its elements with println, showing that removal does not change length and slots default to zero.

Explore Go slices as dynamic alternatives to arrays, declare and initialize a slice, print its contents, measure length with len, and extend the slice to four elements.

Create a slice from an array by selecting indices 1 through 3 (start at 1, end before 4) using short declaration, then show len and cap.

Learn to create a Go slice with the make function, setting length and capacity to five, observe zero-valued integers, and print the slice and its length with len.

Learn to access and update Go slice elements using zero-based indices, declare a five-element int slice, print it, and replace index two's value from three to six.

Learn to measure a slice length in Go using the len function and grow slices with append, as a test shows a change from five to seven elements.

Explore how to append slices in Go using the append function, unpacking with ellipsis, combining test slices, and inspecting results with len and println.

Explore how Go uses a for loop to repeat code and traverse arrays and slices, replacing while or do while. Learn initialization, condition, and post with a 0–4 example.

Use the continue statement in Go to skip the rest of the loop body for the current iteration and proceed to the next, demonstrated by a for loop skipping 2.

Use break to stop a for loop when i equals two, instead of continue, letting control flow continue after the loop. See zero and one printed before termination.

Learn range-based for loops to iterate over slices, arrays, maps, and strings, accessing index and value. See practical examples of printing with println and using underscores to ignore unused values.
