用法: intsprintf(char *str, const char *string,...); sprintf代表“String print”。它将输出存储在sprintf中指定的char缓冲区中,而不是在控制台上进行打印 例: // Example program to demonstratesprintf()#include<stdio.h>intmain(){charbuffer[50];inta =10, b =20, c; c = a + b;sprintf(buf...
再加上'\0'结束符int hours,minutes;hours=seconds/3600;seconds=seconds%3600;minutes=seconds/60;seconds=seconds%60;snprintf(timeStr,sizeof(timeStr),"%02d:%02d:%02d",hours,minutes,seconds);returntimeStr;}intmain(){int seconds=3661;// Example valuechar*time...
sprintf是一个C语言中的函数,用于将格式化的数据写入字符串中。它可以根据指定的格式将数据转换为字符串,并将结果存储在指定的缓冲区中。 生成一个txt文件的步骤如下: 1. 引入相关的头文件:...
函数原型: int sprintf(char *str, const char *format, ...); str是指向一个字符数组的指针,该数组存储了 C 字符串。format是字符串,包含了要被写入到字符串 str 的文本。 功能:发送格式化输出到 str 所指向的字符串。 example2: #include <stdio.h>#include<math.h> //for M_PIintmain() {charstr...

The C standard and POSIX specify that the behavior of sprintf and its variants is undefined when an argument overlaps with the destination buffer. Example: sprintf(dst, "%s and %s", dst, t); // <- broken: undefined behaviorPOSIX specifies that errno is set on error. It also specifies ...
particular format option. Thetypecharacter, which appears after the last optional format field, determines whether the associated argument is interpreted as a character, a string, a number, or pointer. The simplest format specification contains only the percent sign and atypecharacter (for example, ...
Silly example for python 2.7 and up: >>>print"{} ...\r\n {}!".format("Hello","world") Hello ... world! For earlier python versions: (tested with 2.6.2) >>>print"{0} ...\r\n {1}!".format("Hello","world") Hello ... ...
