To determine

What variable is stored in Count.

Answer to Problem 1ICA

The variable stored in Count is 8.

Explanation of Solution

Given data:

Count =0;

for N=10:-0.2:8.5;

Count=Count+1;

end

Answer to Problem 1ICA

The variables stored in in p and C are p=945 and C=4.

Explanation of Solution

Given data:

S=3;

I=2;

P=1;

C=0;

for K=S:I:S^I

P=P*K;

C=C+1;

end
