Example: Use sprintf_s to format data C Kopírovať // crt_sprintf_s.c // This program uses sprintf_s to format various // data and place them in the string named buffer. // #include <stdio.h> int main( void ) { char buffer[200], s[] = "computer", c = 'l'; ...
// 声明数字变量 const num1, num2, num3 = 5, 10, 15 // 调用 Sprintf() 函数 s := fmt.Sprintf("%d + %d = %d", num1, num2, num3) // 使用 WriteString() 函数将结果输出到终端 to write the // "os.Stdout" 为字符串的内容 io.WriteString(os.Stdout, s) }输出结果为:5...

To return formatted text as a string, specify formatSpec as a string instead of a character vector when you call the sprintf function. Convert data and return the result as a string. Get formatSpec = "The current time is: %d:%d %s"; A1 = 11; A2 = 20; A3 = 'a.m.'; str = ...
if the buffer is too small for the text being printed then the buffer is set to an empty string and the invalid parameter handler is invoked. 如果写入的数据长度大于 sizeBuffer - 1 ,将会触发错误。 如在vs2010 Debug模式下: 1 2 3
