What value is stored in uninitialized variables? * Some languages assign a default value as 0 to uninitialized variables. Algorithm Workbench Review Questions: 3-10 3. Write assignment statements that perform the following operations with the variables a, b, and c. * Adds 2 to a and stores the result in b * Set b= 2 +a * Multiplies b times 4 and stores the result in a * set a= b*4 * Divides a by 3.14 and stores the result in b * set b= 3.14/b * Subtracts 8 from b and stored the result in a * set a= b-8 4. Assume the variables result, w, x, y, and z are all integers, and that w = 5, x = 4, y = 8, and z = 2.
