Question

After following statements have executed, find the value of the variable a.

int a=2

while (a<=25)

            a=a*a;

Expert Solution
Step 1

Execution:
initially a=2
iteration:1
a<=25 : 2<=25 //condition satisfied
a=a*a = 2*2 = 4
now, a is 4
iteration:2
a<=25 : 4<=25 //condition satisfied
a=a*a = 4*4 = 16
now, a is 16
iteration:3
a<=25 : 16<=25 //condition satisfied
a=a*a = 16*16 = 256
now, a is 256
iteration:4
a<=25 : 256<=25 //condition is not satisfied, so loop stops

now a is 256
