Question

Write a program in C that takes as input an 8-bit binary number and prints the next 10 binary

numbers. Define a binary number as

int binNum[8];

Use binNum[0] to store the most significant (i.e., leftmost) bit and binNum[7] to store the least

significant bit. Ask the user to input the first binary number with each bit separated by at

least one space.

#include<stdio.h>
int main()
{
    int binNum[8],no[9];
    int i,s=0,j;
    //input the binary number
    printf("Enter the binary number");
    for(i=0;i<8;i++)
    scanf("%d",&binNum[i]);
   
    //display the input number
    for(i=0;i<=7;i++)
   printf("%d ",binNum[i]);
   //condition when the 1ft 5 bit's are 1(from MSB)
   if(binNum[0]==1 && binNum[1]==1 && binNum[2]==1 && binNum[3]==1 && binNum[4]==1)
   {
      no[0]=0;
      for(j=1,i=0;i<8;i++,j++)
      no[j]=binNum[i];
        
      printf("\n Binary Numbers :\n");
    //loop to print the 10 next binary numbers
    for(j=1;j<=10;j++)
    {
       s=1; //assign s to 1 to generate next number
    for(i=8;i>=0;i--) //loop to scan each bit of binary number from LSB to MSB
    {
       if(no[i]==0) //if bit is 0 then add 1 to that position
       {
       no[i]= no[i]+s;
       s=0; //set s to 0
       break;   //terminate the loop
       }
      
       else
       if(no[i]==1 && s==1 ) //if bit is 1 and s=1 theh set the bit to 0 and set s to 1
       {
          no[i]=0;
          s=1; //carry forward bit
           }
   }
   printf("\n");
   //display the next number
   if(no[0]==0) //if the 9th bit is 0 (MSB)
   {
      for(i=1;i<=8;i++)
   printf("%d ",no[i]);
   }
   else
   for(i=0;i<=8;i++)
   printf("%d ",no[i]);

       }
       else

    {
       s=1; //assign s to 1 to generate next number
    for(i=7;i>=0;i--) //loop to scan each bit of binary number from LSB to MSB
    {
       if(binNum[i]==0) //if bit is 0 then add 1 to that position
       {
