Question

int main()
{
  int i,j;
  i='c';

  scanf("%d",&j);   // I will read 'c' here 

  printf("%d %d",i,j);

}

Output is not same.'j' takes garbage value and 'i' takes ascii value of 'c'. Can anybody tell what could be the reason ?

Answer 1

You scanf says:

scanf("%d", &j);

With this sentence scanf will try to parse (convert) the ‘c’ character you are using as input to the function into a number. That’s way you get garbage. C doesn’t know how to turn ‘c’ into a number, because scanf is expecting digits.

Try changing that to:

scanf("%c", &j);

If your printf call is like this:

printf("%d %d", i, j);

You should get the same value, both times: ASCII value of ‘c’ character.
