sprintf函数

函数原型：

int sprintf( char *buffer, const char *format [, argument] ... );

返回值：buffer中存储的字串长度

buffer：存储格式化的字符串

 

例子：

#include <stdio.h>

void main( void )
{
  char  buffer[200], s[] = "computer", c = 'l';
  int   i = 35, j;
  float fp = 1.7320534f;

  /* Format and print various data: */
  j  = sprintf( buffer,     "/tString:    %s/n", s );
  j += sprintf( buffer + j, "/tCharacter: %c/n", c );
  j += sprintf( buffer + j, "/tInteger:   %d/n", i );
  j += sprintf( buffer + j, "/tReal:      %f/n", fp );

  printf( "Output:/n%s/ncharacter count = %d/n", buffer, j );
}

输出

Output:

   String:    computer
  Character: l
  Integer:   35
  Real:      1.732053

character count = 71

 

或者：sprintf( buffer,     "/tString:    %s/nCharacter: %c/ntInteger:   %d/nReal:      %f/n", s , c, i, fp);
