In Go, there are three primary functions for printing output: Print()<\/code>, Println()<\/code>, and Printf()<\/code>. These functions allow you to display data and messages in the console with varying levels of formatting.<\/p>\n\n\n\n

The Print()<\/code> Function<\/h2>\n\n\n\n

The Print()<\/code> function outputs its arguments using their default format without adding spaces or newlines.<\/p>\n\n\n\n

Example:<\/h4>\n\n\n\n

This program demonstrates printing two strings side by side:<\/p>\n\n\n\n

package main\n\nimport ("fmt")\n\nfunc main() {\n  var yamaha, honda string = "Speed", "Thrills"\n\n  fmt.Print(yamaha)\n  fmt.Print(honda)\n}<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Result:<\/strong><\/p>\n\n\n\n
SpeedThrills<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Example:<\/h4>\n\n\n\n
To print each argument on a new line, you can use \\n<\/code>:<\/p>\n\n\n\n
package main\n\nimport ("fmt")\n\nfunc main() {\n  var yamaha, honda string = "Speed", "Thrills"\n\n  fmt.Print(yamaha, "\\n")\n  fmt.Print(honda, "\\n")\n}<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Result:<\/strong><\/p>\n\n\n\n
Speed\nThrills<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Example:<\/h4>\n\n\n\n
Alternatively, one Print()<\/code> can be used to display multiple variables:<\/p>\n\n\n\n
package main\n\nimport ("fmt")\n\nfunc main() {\n  var yamaha, honda string = "Speed", "Thrills"\n\n  fmt.Print(yamaha, "\\n", honda)\n}<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Result:<\/strong><\/p>\n\n\n\n
Speed\nThrills<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Example:<\/h4>\n\n\n\n
To add a space between string arguments, include a space explicitly:<\/p>\n\n\n\n
package main\n\nimport ("fmt")\n\nfunc main() {\n  var yamaha, honda string = "Speed", "Thrills"\n\n  fmt.Print(yamaha, " ", honda)\n}<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Result:<\/strong><\/p>\n\n\n\n
Speed Thrills<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Example:<\/h4>\n\n\n\n
If the arguments are not strings, Print()<\/code> automatically inserts a space:<\/p>\n\n\n\n
package main\n\nimport ("fmt")\n\nfunc main() {\n  var yamaha, honda = 100, 200\n\n  fmt.Print(yamaha, honda)\n}<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Result:<\/strong><\/p>\n\n\n\n
100 200<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
The Println()<\/code> Function<\/h2>\n\n\n\n
The Println()<\/code> function is similar to Print()<\/code> but automatically adds a space between its arguments and appends a newline at the end.<\/p>\n\n\n\n
Example:<\/h4>\n\n\n\n
package main\n\nimport ("fmt")\n\nfunc main() {\n  var yamaha, honda string = "Speed", "Thrills"\n\n  fmt.Println(yamaha, honda)\n}<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Result:<\/strong><\/p>\n\n\n\n
Speed Thrills<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
The Printf()<\/code> Function<\/h2>\n\n\n\n
The Printf()<\/code> function allows for advanced formatting of its arguments. It formats the input according to specific “verbs.”<\/p>\n\n\n\n
Common Formatting Verbs:<\/h4>\n\n\n\n
    \n
  • %v<\/code>: Displays the value of the argument.<\/li>\n\n\n\n
  • %T<\/code>: Displays the type of the argument.<\/li>\n<\/ul>\n\n\n\n
    Example:<\/h4>\n\n\n\n
    package main\n\nimport ("fmt")\n\nfunc main() {\n  var yamaha string = "Speed"\n  var honda int = 120\n\n  fmt.Printf("yamaha has value: %v and type: %T\\n", yamaha, yamaha)\n  fmt.Printf("honda has value: %v and type: %T", honda, honda)\n}<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    Result:<\/strong><\/p>\n\n\n\n
    yamaha has value: Speed and type: string\nhonda has value: 120 and type: int<\/pre><\/div>\n\n\n\n
