Question

Find the output of the following:

int a[]={5,7,9,3,1};

for(int i=0;i<=4;i++)

System.out.println(Math.pow(a[i],2)-1);​

Answer 1

Output:

24.0

48.0

80.0

8.0

0.0

Answer 2

Question:-

Find the output of the following code.

Solution:-

Given code,

int a[]={5,7,9,3,1}

for(int i=0;i<=4;i++)

System.out.println(Math.pow(a[i],2)-1);

When i=0

a[i]=5

5^2 - 1=24.0

When i=1

a[i]=7

7^2 - 1=48.0

When i=2

a[i]=9

9^2-1=80.0

When i=3

a[i]=3

3^2 - 1=8.0

When i=4

a[i]=1

1^1 - 1=0.0

Output:-

Hence, the required output is,

24.0

48.0

80.0

8.0

0.0
