sscanf("%hello,world! %123", "%%%s%%123", str_mid); 注意:sscanf 函数解析字符串时在格式字符串会使用%s,而%s会将输入字符串一直匹配,直到出现空白字符或已经达到字符串最大匹配长度。 ✨3.2 sscanf 函数解析数字 解析整数: int i; sscanf("123", "%d", &i); 解析浮点数: float f; sscanf("1....

注意sscanf_s,当读入的类型是整数或其它长度可以确定的类型时,不能在类型后面跟上长度,但是对于字符串类型(char*)长度无法得知则必须在类型后面明确指出字符串的最大长度(即可以容纳的空间)。举例如下:4567891011intmain(void)12{13chartokenstring[]="151214...";14chars[81];15charc;16inti;17floatfp;18#...

int sscanf(const char* s, const char* format, ...); 其中,s表示字符串,format用来指定字符串中提取的数据格式,...表示要提取数据的地址。 例如: char s[] = "1 2 3.14159"; int i; float f; sscanf(s, "%d %f", &i, &f); 上述代码中,s是字符串,%d表示提取整数,%f表示提取浮点数,&i和...
