about char type and int ;

[forrest2001]

there is:
strchr (const char * , int)
in my code : char* name="shi lin";
char *p;
p=strchr(name,' ');
//or p=strchr(name, 'l');
ask: here ' ' and 'l ' is int type??

answer:char type will be proccessed as ASCⅡ in c/c++
example:
code:
char c1,c2;
c1=48;
c2='0';
printf("%c,%c\n",c1,c2);
printf("%d,%d",c1,c2);
result:
0,0
48,48

char 型可自动转换成 int 型

[jishiping]

在C/C++里，调用函数时不要求类型一定要完全一致，有些类型编译器
可以自动转换。如:
char -> int int -> long int -> float int -> double

就是char型字符的ASCII值

char变成int会"expand",而int变成char会"slice".
