Question
What will be the value of the variable “B” in the following pseudocode if the value of variable “A” is 5.2 and the value of variable “B” is 15? if A = 5.2 then if B > 20 then A = A + 5 else B = B – 3.5 endifelse if A = 6 then A = 0 B = 0 endifendifa.5.2b.15c.0d.11.5
Solution
Para determinar el valor de la variable "B" en el pseudocódigo dado, sigamos los pasos uno por uno:
- Inicialmente, A = 5.2 y B = 15.
- Evaluamos la primera condición:
if A = 5.2 then- Esta condición es verdadera porque A es efectivamente 5.2.
- Dentro de esta condición, evaluamos la siguiente condición:
if B > 20 then- Esta condición es falsa porque B es 15, que no es mayor que 20.
- Dado que la condición
B > 20es falsa, ejecutamos el bloqueelsecorrespondiente:B = B - 3.5- Sustituyendo el valor de B:
B = 15 - 3.5 - Calculamos:
B = 11.5
Por lo tanto, el valor de la variable "B" después de ejecutar el pseudocódigo es 11.5.
La respuesta correcta es: d. 11.5
