Question

My task is to get an input, print out the character and the ASCII value, and to present them each 8 for 1 line. For every input I’m typing I’m getting also the value of the newline character and I don’t want to print it.

This is my code:

#include <stdio.h>

int main()    
{       
    char ch;
    int count = 0;

    printf("please type an input:\n");
    while ((ch = getchar()) != '#')          
    {
        ++count;           
        printf("%c=%d ", ch, ch);
        if (count%8 == 0) printf("\n");
    }        
}

You can use another getchar() right after reading the first one:

  while ((ch = getchar()) != '#')
  {
       getchar();  // To eat the newline character
       // Rest of code
  }

Or you can use scanf() and rewrite the loop equivalently:

   while (scanf(" %c", &ch)==1)
    {
        if(ch != '#')
        {
          ++count;
          printf("%c=%d ", ch, ch);
          if (count%8 == 0)
             printf("\n");
        }
    }
