第4步– 使用strconv.FormatBool()函数。 第5步– 将结果存储在一个变量中并打印在屏幕上。 例子 // Go language program to illustrate How to convert Boolean to Stringpackagemain// import the required packagesimport("fmt""strconv")// fmt package allows us to print anything.// strconv package ...
strconv.FormatBool(bool) string fmt.Sprintf(string, bool) string 与"%t" 或"%v" 格式化程序。 请注意, strconv.FormatBool(...) 比fmt.Sprintf(...) _快得多_,如以下基准所示: func Benchmark_StrconvFormatBool(b *testing.B) { for i := 0; i < b.N; i++ { strconv.FormatBool(true...
