<pre>
原型：extern int toascii(int c);
用法：#include <ctype.h>
功能：將字符c轉(zhuǎn)換為ascii碼
說明：toascii函數(shù)將字符c的高位清零，僅保留低七位。返回轉(zhuǎn)換后的數(shù)值。
舉例：
// toascii.c
#include <syslib.h>
#include <ctype.h>
main()
{
char s[]="文曲星-BJGGV";
int i=12; // length of string s
clrscr(); // clear screen
textmode(0xE0); // make sure LCD mode is 3 big line
printf("%s\n",s);
for(i=0;i<12;i++)
{
putchar(toascii(s[i]));
}
getchar();
return 0;
}
相關(guān)函數(shù)：無
