问题描述
好标题pretty多总结起来。我想用C ++中像ASC(0),并希望使该程序与平台无关的,所以不要想用48!任何帮助AP preciated。
Well the title pretty much sums it up. I want to use something like asc("0") in C++, and want to make the program platform independent so don't want to use 48! Any help appreciated.
推荐答案
您可以简单地使用单引号作字符常量:
You can simply use single-quotes to make a character constant:
char c = 'a';
字符类型的是的数字类型,因此对于递增
和 CHR $没有真正的需要C $ C>当量。
The character type is a numeric type, so there is no real need for asc
and chr
equivalents.
下面是打印出一个字符串的字符值的一个小例子:
Here's a small example that prints out the character values of a string:
#include <stdio.h>
int main(int argc, char **argv) {
char str[] ="Hello, World!";
printf("string = \"%s\"\n", str);
printf("chars = ");
for (int i=0; str[i] != 0; i++)
printf("%d ", str[i]);
printf("\n");
return 0;
}
输出是:
string = "Hello, World!"
chars = 72 101 108 108 111 44 32 87 111 114 108 100 33
