Question

I tried the below program .

INPUT-: i want help
Desired OUTPUT-:Words=3 Characters=9

But the actual output deviates from the desired.
Can someone tell what is my mistake .

include

void main()
{
  int countch=0;
  int countwd=1;

  printf("Enter your sentence in lowercase: ");
  char ch='a';
  while(ch!='\r')
  {
    ch=getche();
    if(ch==' ')
      countwd++;
    else
      countch++;
  }

  printf("\n Words = ",countwd);

  printf("Characters = ",countch-1);

  getch();

}

Answer 1

There are few observations which you might find of some use:
1. You are using getch & getche which are both non-standard functions. Make use of getchar instead. In this case as already pointed in unwind’s response you need to use int for the return type.
2. Please change the return type of main from void to int.
3. You are not specifying the formats in printf. Please add %d specifier to print integers.
I have not used codepad but ideone allows you to add inputs to your programs. Here is a reference based on your sample on ideone.
Hope this helps!
