好的,我要做的是输入二进制数IN IN TERMINAL,可能使用argv []或其他东西,然后将其分成每个数字。 我有这个:
int bits[31];
for(int i=0; i<31 && 1 == fscanf(stdin, "%1d", &bits[i]); ++i);
这适用于scanf,但我想要一种简单的方法,但输入在终端
答案 0 :(得分:0)
此代码接受二进制数作为程序参数。大多数代码都致力于清除任何无效的参数。
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char *argv[])
{
int len;
long bin;
if (argc < 2) {
printf("Please try again with an argument supplied\n");
return 1;
}
len = strlen(argv[1]);
if (strspn(argv[1], "01") != len) {
printf("The argument is not a binary number\n");
return 1;
}
printf("First bit is %c\n", argv[1][0]);
printf("Last bit is %c\n", argv[1][len-1]);
bin = strtol(argv[1], NULL, 2);
printf("As a long integer variable, the input is %ld\n", bin);
return 0;
}
没有错误检查(崩溃除外),这会减少到
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char *argv[])
{
int len;
if (argc > 1) {
len = strlen(argv[1]);
printf("First bit is %c\n", argv[1][0]);
printf("Last bit is %c\n", argv[1][len-1]);
printf("As a long integer the input is %ld\n", strtol(argv[1], NULL, 2));
}
return 0;
}
