我已经弄清楚如何获取用户的输入(字符串)并从中获取每个字母并给出每个字母的二进制等效项。
问题是我希望每个字母在屏幕上显示时每行一个字母来给出一个二进制数。我需要帮助。
例如:
C 0 1 0 0 0 0 1 1
h 0 1 1 0 1 0 0 0
a 0 1 1 0 0 0 0 1
n 0 1 1 0 1 1 1 0
g 0 1 1 0 0 1 1 1
这是我使用的代码:
#include <stdio.h>
int main()
{
//get input
printf( "Enter a string: " );
char s[255];
scanf( "%[^\n]s" , s );
//print output
printf( "'%s' converted to binary is: " , s );
//for each character, print it's binary aoutput
int i,c,power;
for( i=0 ; s[i]!='\0' ; i++ )
{
//c holds the character being converted
c = s[i];
//for each binary value below 256 (because ascii values < 256)
for( power=7 ; power+1 ; power-- )
//if c is greater than or equal to it, it is a 1
if( c >= (1<<power) )
{
c -= (1<<power); //subtract that binary value
printf("1");
}
//otherwise, it is a zero
else
printf("0");
}
return 0;
}
