Question

Write a program in C that reads a string of bits( so either a one or zero) in from the user one char at a time using the function getChar, which returns a char. hint in order to convert a char to an int, subtract the character. Then store the bits into an array.

start with this:

#include "stdio.h"
#define MAX_BITS 32

int main() {

printf("Enter up to 32 bits (hit 'enter' to terminate early): ");

char bit = getchar(); // reads the first bit (as a char)

return 0;
}

Answer 1

#include<stdio.h>
#define MAX_BITS 32

int main() {

char array[MAX_BITS];//declaring char array to read string of bits

int i=0;
printf("Enter up to 32 bits (hit 'enter' to terminate early): ");

while(1)
{

char bit = getchar(); // reads the first bit (as a char)
if(bit=='\n')break;//if a line entered then breaking loop
array[i++]=bit;//assigning to array
}

array[i]='\0';

//displaying output
printf("String entered: %s",array);
return 0;
}

output:

Enter up to 32 bits (hit 'enter' to terminate early): 1011011
String entered: 1011011
