Generate a code using c$++$ programe for Carlo Fair Coin Algorithm

Input Total number $n$ of random flips of a fair coin to be generated in the simulation.

Output Probability of getting a head when we flip a fair coin.

Step $1$ Initialize: COUNTER $=0.$

Step $2$ For $i=1,2,$dots,$n,$ do Steps $3$ and $4.$

Step $3$ Obtain a random number $x_i$ between $0$ and $1.$

Step $4$ If $0x_{i}0\mathrm{.}5,$ then COUNTER $=$ COUNTER $+1.$ Otherwise, leave COUNTER as is$.$

Step $5$ Calculate head
