In Go<\/strong>, the for<\/code> loop is the only looping construct provided by the language. It’s versatile and efficient for executing a block of code multiple times, often with a unique value in each iteration. Each cycle through the loop is referred to as an iteration.<\/p>\n\n\n\n

Syntax of a for Loop<\/h2>\n\n\n\n

The for<\/code> loop in Go can include up to three statements:<\/p>\n\n\n\n

for initialization; condition; increment {\n   \/\/ code to execute during each iteration\n}\n<\/pre><\/div>\n\n\n\n
    \n
  • Initialization<\/strong>: This sets up the loop control variable.<\/li>\n\n\n\n
  • Condition<\/strong>: This evaluates before each iteration. If TRUE<\/code>, the loop continues; if FALSE<\/code>, the loop ends.<\/li>\n\n\n\n
  • Increment<\/strong>: This modifies the loop control variable after each iteration.<\/li>\n<\/ul>\n\n\n\n
    Note: These statements don\u2019t need to be included within the loop header but must exist elsewhere in the code.<\/p>\n\n\n\n
    Example 1: Counting from 0 to 4<\/h2>\n\n\n\n
    package main\nimport ("fmt")\n\nfunc main() {\n  for bikes := 0; bikes < 5; bikes++ {\n    fmt.Println(bikes)\n  }\n}\n<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    Output<\/strong>:<\/p>\n\n\n\n
    0\n1\n2\n3\n4\n<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    Explanation<\/strong>:<\/p>\n\n\n\n
      \n
    1. Initialization<\/strong>: bikes := 0<\/code> sets the starting value to 0.<\/li>\n\n\n\n
    2. Condition<\/strong>: bikes < 5<\/code> ensures the loop runs as long as bikes<\/code> is less than 5.<\/li>\n\n\n\n
    3. Increment<\/strong>: bikes++<\/code> increases the value of bikes<\/code> by 1 in each iteration.<\/li>\n<\/ol>\n\n\n\n
      Example 2: Counting in Tens<\/h2>\n\n\n\n
      package main\nimport ("fmt")\n\nfunc main() {\n  for motorcycles := 0; motorcycles <= 100; motorcycles += 10 {\n    fmt.Println(motorcycles)\n  }\n}\n<\/pre><\/div>\n\n\n\n
      <\/p>\n\n\n\n
      Output<\/strong>:<\/p>\n\n\n\n
      0\n10\n20\n30\n40\n50\n60\n70\n80\n90\n100\n<\/pre><\/div>\n\n\n\n
      <\/p>\n\n\n\n
      Explanation<\/strong>:<\/p>\n\n\n\n
        \n
      1. Initialization<\/strong>: motorcycles := 0<\/code> starts at 0.<\/li>\n\n\n\n
      2. Condition<\/strong>: motorcycles <= 100<\/code> keeps the loop running while motorcycles<\/code> is less than or equal to 100.<\/li>\n\n\n\n
      3. Increment<\/strong>: motorcycles += 10<\/code> increases the value by 10 with each cycle.<\/li>\n<\/ol>\n\n\n\n
        Continue Statement<\/h2>\n\n\n\n
        The continue<\/code> statement skips the remainder of the current loop iteration and proceeds to the next iteration.<\/p>\n\n\n\n
        Example: Skipping a specific value (e.g., 3):<\/p>\n\n\n\n
        package main\nimport ("fmt")\n\nfunc main() {\n  for models := 0; models < 5; models++ {\n    if models == 3 {\n      continue\n    }\n    fmt.Println(models)\n  }\n}\n<\/pre><\/div>\n\n\n\n
        <\/p>\n\n\n\n
        Output<\/strong>:<\/p>\n\n\n\n
        0\n1\n2\n4\n<\/pre><\/div>\n\n\n\n
        <\/p>\n\n\n\n
        Break Statement<\/h2>\n\n\n\n
        The break<\/code> statement halts the loop\u2019s execution entirely.<\/p>\n\n\n\n
        Example: Terminating the loop when a condition is met:<\/p>\n\n\n\n
        package main\nimport ("fmt")\n\nfunc main() {\n  for brands := 0; brands < 5; brands++ {\n    if brands == 3 {\n      break\n    }\n    fmt.Println(brands)\n  }\n}\n<\/pre><\/div>\n\n\n\n
        <\/p>\n\n\n\n
        Output<\/strong>:<\/p>\n\n\n\n
        0\n1\n2\n<\/pre><\/div>\n\n\n\n
        <\/p>\n\n\n\n
        Nested Loops<\/h2>\n\n\n\n
        Loops can be nested, meaning one loop is placed inside another. The inner loop runs completely during each iteration of the outer loop.<\/p>\n\n\n\n
        Example: Combining two lists, such as adjectives and motorcycle brands:<\/p>\n\n\n\n
        package main\nimport ("fmt")\n\nfunc main() {\n  adjectives := [2]string{"sleek", "powerful"}\n  brands := [3]string{"Ducati", "Yamaha", "Honda"}\n  for i := 0; i < len(adjectives); i++ {\n    for j := 0; j < len(brands); j++ {\n      fmt.Println(adjectives[i], brands[j])\n    }\n  }\n}\n<\/pre><\/div>\n\n\n\n
        <\/p>\n\n\n\n
        Output<\/strong>:<\/p>\n\n\n\n
        sleek Ducati\nsleek Yamaha\nsleek Honda\npowerful Ducati\npowerful Yamaha\npowerful Honda\n<\/pre><\/div>\n\n\n\n
        <\/p>\n\n\n\n
        Using the range Keyword<\/h2>\n\n\n\n
        The range<\/code> keyword provides a convenient way to iterate over elements in arrays, slices, or maps. It returns both the index and the value.<\/p>\n\n\n\n
        Syntax<\/strong>:<\/p>\n\n\n\n
        for index, value := range collection {\n   \/\/ code to execute during each iteration\n}\n<\/pre><\/div>\n\n\n\n
        <\/p>\n\n\n\n
        Example: Iterating through motorcycle brands:<\/p>\n\n\n\n
        package main\nimport ("fmt")\n\nfunc main() {\n  brands := [3]string{"Suzuki", "Honda", "Ducati"}\n  for idx, val := range brands {\n    fmt.Printf("%v\\t%v\\n", idx, val)\n  }\n}\n<\/pre><\/div>\n\n\n\n
        <\/p>\n\n\n\n
        Output<\/strong>:<\/p>\n\n\n\n
        0      Suzuki\n1      Honda\n2      Ducati<\/pre><\/div>\n\n\n\n
        <\/p>\n\n\n\n
        Additional Tips for range<\/code><\/h4>\n\n\n\n
          \n
        • To ignore the index<\/strong>: for _, val := range brands { fmt.Println(val) }<\/code> Output<\/strong>: Suzuki Honda Ducati<\/code><\/li>\n\n\n\n
        • To ignore the value<\/strong>: for idx, _ := range brands { fmt.Println(idx) }<\/code> Output<\/strong>: 0 1 2<\/code><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
