int sprintf( char *buffer,
const char *format[,

);
buffer:storage location for output
存儲位置
format:format-control string :格式化控制的字元串
argument:optional arguments :可選的參數

//sprintf的作用是通過格式化的方式将内容寫到字元串中

sprintf案例2
求字元串的長度
3.通過goto的方式實作求字元串的長度
4.通過遞歸的方式實作求字元串的長度
5.字元串查找
char *strstr( const char *string,
const char *strcharset);
each of these functions returns a pointerto the first occurrence of
strcharset in string, or nullif strcharset does not appear in
string. if strcharsetpoints to a string of zero length, the function returns
string.
說明：意思是說，傳回的是字元串第一次出現的指針位置。

main(int
argc,

str1[100] =

= strstr(str1,str2);
if (p
== null)
printf("沒有找到");
else
printf("找到%p,%c",p,*p);

return 0;
