11. The following algorithm should calculate the summation of the even integers from a to b. The condition of the if statement is missing (shown by dots). Which of these is the missing condition? int a,b, sum =0; cin ab; while (a=b) \{ if (.. sum=sum+a; a=a+1; A) a /2=0 B) a %2=0 C) a%b=0 D) a>=b 12. The following algorithm displays the numbers 110, but there is important missing operation (shown by dots). Which of these is the missing operation? int x=1; while (x10 D) x10;c++cout)cendl; A) The loop is finite B) The loop doesn't make any round C) The loop prints only the number 1 D) None of the Choices
