golang string to uppercase
In Golang, it is very simple to convert a string into uppercase letters. You can use the ToUpper() function in the strings package.
The following is a sample code:
1 2 3 4 5 6 7 8 9 10 11 12 |
|
Output:
1 2 |
|
As can be seen, the ToUpper() function converts all letters in the string to uppercase and returns a new string. Original uppercase letters in the string are not affected.
It should be noted that the ToUpper() function can only recognize letters in the ASCII character set. If you want to convert characters in non-ASCII character sets to uppercase, you need to use the ToUpper() function in the unicode package.
If you need to convert specific parts of the string to uppercase, you can do this by slicing and splicing. For example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
|
Output:
1 |
|
Use the Split() function to split the string into two parts, then process the first letter and the remaining parts respectively, and finally splice them into a new string.
In general, the string conversion operation in Golang is very simple. You only need to use the built-in ToUpper() function or manual splicing. In actual development, you may encounter some string encoding problems, which need to be handled according to specific circumstances.
